Being an orthodontist allows me to watch my patients’ amazing transformations when their smiles are improved with orthodontic treatment. The excitement and anticipation that go along with the first visit, all the way to the amazing smiles at the end of treatment, are what make what I do worthwhile.

A native of Peoria, I moved back to my hometown after completing my orthodontic residency at St. Louis University in 1997. I’m a Bergan High School alumnus and a graduate of the University of Louisville Dental School. My wife, Michelle, is also a Central Illinois native and is a graduate of Woodruff High School and Bradley University. We have been married for 18 years and have three daughters. I love spending time with my family and enjoy boating, photography, flying radio-controlled aircraft, model trains, and recreational hockey. I’m a little “old school” when it comes to music, so you may hear some songs from the 80s when you visit our office.

As an orthodontist, I pride myself on providing my patients with state-of-the-art treatment techniques and equipment. I am a member of the American Association of Orthodontists, Illinois Society of Orthodontists, Illinois State Dental Society, Peoria District Dental Society, American Dental Association, and Orthodontic Education and Research Foundation. I also belong to several local dental study clubs and organizations.

I look forward to meeting you and helping you to a better smile!

- Erin Olsen

- Molly Legaspi

After three years and jaw surgery, I got my braces off!! I’d just like to say if anyone knows someone who wants braces I highly recommend Dr. Cusack and his wonderful staff!! They are really awesome and really care about each individual person who comes to them! So for anyone that needs braces, go to Dr. Cusack because my teeth (and jaw) used to be horrible and now I love them!

- Amelia DeCeanne

Always enjoyed my times going here and my teeth look beautiful to this day. Thanks Pat and team!

- Andrew Kistner

Had a wonderful experience with Dr. Cusack and his team for my Invisalign. The entire staff is very friendly and accommodating, worked well around my schedule, and there were very short wait times when I arrived for each appointment. In and out quickly which was awesome. They worked with my financial situation as far as payments, and the whole process was definitely worth it. Very satisfied with the end result. The funny thing is I’d been to a different orthodontist in the Peoria area before who told me Invisalign was not an option for my teeth, which was really disheartening since at my age I really didn’t want to do braces. They said I’d have to get braces or eventually have a tooth removed!! Clearly they were wrong, so I’m very glad my dentist recommended this place. Thank you so much Dr. Cusack and team!!

- Mary Spengler

Best, best, best place by far…love my smile!! Plus, everyone there is very sweet and nice!

Very impressed! Friendly staff, clean efficient office, and very good with after braces are off with teeth looking great & staying that way!! Good job to all employees!!!

- Sue Haussmann

When I noticed my teeth were moving about two years ago, I drug my feet to find an orthodontist. After the problem began to make me self-conscious I asked friends and family for a recommendation. Dr. Pat Cusack was the overwhelming response, so I made an appointment to see him. It was one of my best decisions. From the moment I stepped foot in his office I felt comfortable. For starters, the office is clean and modern and the staff is wonderful. Then there is Dr. Cusack himself. He has one of the nicest smiles I’ve ever seen, which is very reassuring when you’re going to him to fix your smile. It is obvious by his smile, and those who work for him, that he knows what he is doing.

My problem was subtle to others but significant to me. I had braces when I was 13 and since then my bite had shifted and it affected the way my smile looked. I was a news anchor, on television each night, and I worried the thousands of viewers would notice. Dr. Cusack suggested I try Invisalign. He promised people wouldn’t notice as the clear, invisible retainers corrected my smile. He was right. Unless I told someone, they really were not noticeable. One night I even anchored the news in them (by accident) and not one person detected a difference.

My experience with Dr. Cusack and his staff was impeccable. I would recommend him to anyone. He is an honest doctor and he made my experience not only easy, but almost fun. I have honestly never been happier with my smile than I am now because of Dr. Cusack

- Ashlee McNamee

We have a long standing relationship with Cusack Orthodontics with 3 sons out of braces and 1 currently going through treatment. The results are outstanding and the boys' teeth never looked better!!! Dr. Cusack and his staff are always very friendly and accommodating. The office is very parent and patient friendly with fun things for the patients to do while in the waiting room and even monthly trivia questions with the winners receiving gift cards. I would highly recommend Cusack Orthodontics to anyone who would love to see their smile be the best that it can be!!!!

- Lori Donlan

I bought my daughter to Cusack orthodontics for her initial appointment. Dr. Cusack suggested partial braces. The process from start to finish was a great experience. The staff was knowledgeable and friendly!! My daughter loves her new smile! Big thanks to Dr. Cusack and staff for boosting her self-esteem!!

- Tiffany Kamrath

I love this office. Friendly atmosphere. Everyone is very professional and efficient.

- Janelle Boyer

Absolutely love Cusack Orthodontics! I remember dreading these appointments when I was a kid but my daughter actually looks forward to her office visits! The doctor and staff are outstanding and the office environment is professional and pleasant.

Straight teeth look great, function better, are easier to clean, and are more likely to last your lifetime. Orthodontic treatment is a wonderful investment with life-long returns.

A Straight Smile is a Healthy Smile!

Straight teeth and jaws that align properly mean that the rest of the mouth and face can grow proportionally, ensuring good oral health. Correcting an abnormal bite can also help ward off oral health problems such as tooth decay, gum disease, and abnormal wear of tooth enamel.

Beautiful Smiles Build Confidence!

Crooked, crowded, unevenly-spaced teeth present obstacles for the confidence level of both children and adults. Straight, healthy, clean teeth build pride and comfort when interacting with others – from making new friends, to participating in class, to sharing photos, to going on job interviews. Many patients complain of being teased for how their teeth look. A beautiful smile paves the way for easier socialization at school, in groups, during extracurricular activities, and at work.


child sore from orthodontic emergency


Headaches, toothaches, sinus problems, dry mouth, snoring, drooling, bad breath, and insomnia are all symptoms of a smile that isn’t straight, jaws that aren’t aligned, or teeth that are too close together – or not quite close enough. Oftentimes, however, the mouth is the last place we check for signs of discomfort, lossof sleep, or even a simple headache.

If your child’s pediatrician can’t figure out why he or she isn’t sleeping well or experiencing headaches or other problems for which there seems to be no cause, a simple 30-minute exam in our office could answer many of those questions and begin a road to resolution.

Proper Development

orthodontic examination by dr cusack for braces or invisalign teen in peoria il

Proper Development

The mouth is like a giant puzzle and all of the pieces slowly come together during growth and development. But what happens when the pieces of the puzzle don’t fit together properly?

The result can be a series of orthodontic problems that cause pain and discomfort. For example, a narrow upper jaw will often produce a shift in the lower jaw to one side when your child bites down because it is “more comfortable” that way. This shift creates a cross bite that can wear down back teeth prematurely and also grow the lower jaw asymmetrically, shifting the dental midlines. If not corrected, this condition can eventually lead to problems in the joints of the jaws. Early treatment appliances such as an orthodontic expander at the proper time of development can correct these conditions.

Choosing to straighten your teeth is a big decision that affects not only your appearance, but your lifestyle as well.

As an adult, you may be looking to improve your smile for business and social reasons, or even for a special occasion like your wedding day. Or perhaps you're a teen or the parent of a teen looking for an effective yet modern-day solution. Either way, Invisalign® and Invisalign Teen® can provide a simple way to accomplish this without having to put your life on hold. Take a moment to learn more about the Invisalign treatment process and how it can help you.

Invisalign Teen

invisalign teen logo

Let’s face it. With school, sports, dating, and hanging out with friends, getting metal braces might not be at the top of your list of favorite things to do. Guess what? With Invisalign Teen®, you can straighten your teeth without metal wires and brackets getting in the way. You’re free to enjoy the things that make these the best times of your life.


Invisalign Teen aligners are made of a smooth, clear plastic that is virtually invisible!

Your friends probably won’t even know you’re wearing them. Enjoy the confidence of showing your smile every day while moving your teeth at the same time! That can make for a better social life overall.


With Invisalign Teen, the aligners are completely removable, allowing you to eat all of your favorite foods whenever you want. This also means you can easily keep brushing and flossing as you normally would for proper oral hygiene.


Whether you play sports or a musical instrument, a mouth full of metal can hold you back from enjoying the things you want to. It’s hard to perform at your best knowing you could get hit in the mouth with a ball, or cut your lip trying to hit that note on the trumpet. Invisalign Teen helps you focus on doing what you do best—being a teen.

Getting Started

lori from dr cusacks orthodontic office in peoria il providing braces and invisalign

The road to a beautiful and healthy smile starts right here with some information about our office and policies.

The Initial Visit

The Initial Visit

We are always excited about meeting new patients during their first visit to our office. The initial appointment consists of a thorough examination and consultation. It is important to analyze each patient's specific needs, since in-depth planning leads to superior results and higher patient satisfaction. We know your time is valuable, so to expedite treatment, we may do diagnostic records on this visit. The records include X-rays, photos, and impressions for study models that are necessary for developing the appropriate treatment plan.

During this consultation visit we discuss treatment options, time frames, and financial arrangements. We make sure that our patients and their parents leave the office with a clear understanding of their specific needs, what the treatment will consist of, and how long it will take. Dr. Cusack and his staff take the time to educate, explain, and answer all of your questions.

These are some of the most common questions at the initial visit:

  • Is this a condition that orthodontics can address?
  • Is treatment needed now or should treatment be delayed until appropriate growth, tooth eruption, or other factors have occurred?
  • What treatment procedures will be used to correct the problem?
  • Is there room for all of the permanent teeth?
  • How long will treatment take?
  • How much will it cost?
  • What are my payment options?

Financial Information

Financial Information

We know that outstanding customer service can only be provided with appropriate fees and flexible payment options. There is no charge for your initial examination or diagnostic orthodontic records. A detailed diagnosis and the formulation of the treatment plan by Dr. Cusack are also complimentary. Fees are determined based on the finalized treatment plan(s) and estimated treatment length after Dr. Cusack has carefully studied your orthodontic records.

  • Many of our in-house payment plans include a down payment and monthly payments with 0% interest, while strong credit may preclude the down payment.
  • In addition, there is a discounted fee for payment-in-full at the start of treatment.
  • We also offer flexible third-party financing with a low interest rate (with qualifying credit).
  • We have a "Family Care Program" where we extend a discounted fee for other family members who also need orthodontic care.
  • If a child undergoes early or interceptive orthodontic treatment, we also offer a reduced fee for the following full-braces phase of treatment.

Our flexible payment arrangements are designed to make orthodontic treatment affordable for everyone. We offer automatic debits from a checking or savings account, or automatic credit card payments. We accept assignment of benefits from most insurance companies, and this could lower both your down payment and monthly payments.

We will work with you to create a payment plan that fits your budget, and you will know what to expect before beginning treatment. As always, we will do everything possible to provide you with a positive experience!

The Bonding Appointment

The Bonding Appointment

Dr. Cusack will put the braces on at the bonding appointment. This one-time appointment takes about an hour. Brackets are placed on the teeth with special orthodontic glue. A carefully selected metal archwire is then placed over the brackets. Tiny elastic loops attach the wire to each bracket. The pressure from the wire gradually works to straighten the teeth. There are different options for bracket materials and a rainbow of fun color choices for elastic bands (which are changed at every adjustment appointment) for a unique and colorful smile. You will be sent home with a “Cusack Orthodontics Survival Kit” with everything you need to get started taking care of your new braces.

Adjustment Appointments

Adjustment Appointments

After the bonding appointment, the patient comes back for regular adjustments at four- to six-week intervals. These adjustment appointments typically last about thirty minutes. At each adjustment appointment, the previous elastic bands will be removed, new archwires may be placed, and different colored elastics can be chosen.

The American Association of Orthodontists recommends that children have their first orthodontic screening by the age of seven or sooner if there are concerns or questions about their bite. This is not necessarily to start treatment but to evaluate the need for intervention by looking at jaw growth or the lack of room for permanent teeth. An orthodontist can carefully monitor growth and development and begin treatment when it is ideal. Please don’t wait until all the baby teeth are lost. There are great advantages to starting treatment early.

Early or Inceptive Treatment

child smiling needing braces from orthodontist pat cusack in peoria il

Early or Inceptive Treatment

This phase of treatment is for the orthopedic correction of the jaws and alignment of the front teeth to facilitate in the eruption of the remaining permanent teeth. Appliances are sometimes placed on the upper and/or lower permanent teeth.

Treatment usually begins after the four upper front teeth have erupted (around the ages of seven to nine.) The patient may wear space maintainers or expanders, which bring the teeth into a more ideal biting position. Interceptive treatment can be used to enhance the growth pattern in children to help create more room for the eruption of permanent teeth. Treatment can be accomplished within 12 months with a “holding” pattern (i.e. retainers.)

Advantages of Interceptive Treatment

  • Improves the relationship of the upper and lower jaws.
  • Utilizes the maximum advantage of the child’s growth.
  • The bone is more pliable and teeth move more easily.
  • Moves protruding teeth back so that they will be less susceptible to injury.
  • Improves facial appearance and self-esteem.
  • Patient is cooperative and enthusiastic at this age.
  • Helps reduce chance of removing permanent teeth later.
  • Reduce length of time wearing full braces.
  • Could possibly eliminate the need for full braces later.

Comprehensive Treatment

teen smiling after braces or invisalign removed from orthodontist pat cusack

Comprehensive Treatment

Comprehensive treatment is commonly known as full braces or complete braces. This phase of treatment concerns all of the permanent teeth and establishes the proper final occlusion. Orthodontic retention is the only phase remaining after this phase.

Orthognathic Surgery

xray tracing image from orthodontist pat cusack in peoria il for braces or invisalign

Orthognathic Surgery

Orthognathic surgery (also known as corrective jaw surgery) treats and corrects abnormalities of the facial bones (size, shape, and location). These abnormalities can often cause difficulty with chewing, talking, sleeping and other routine activities. Orthognathic surgery can correct these problems and improve the overall appearance of the facial profile. Orthognathic surgery may be unnecessary if orthognathic treatment can correct the problem during early growth of the jaws.

If your bite requires orthognathic surgery, Dr. Cusack is able to demonstrate the overall aesthetic and functional benefits of orthognathic surgery using the latest in digital imaging technology.

Adult Treatment

adult with braces smiling for orthodontist peoria il

Adult Treatment

Braces aren’t just for kids. All ages can benefit from a healthy bite. Tooth alignment can be changed at any age if your gums and bone structures are healthy, which we evaluate with every adult patient. Crooked teeth and a bad bite can contribute to gum and bone loss, tooth decay, abnormal wear of the tooth enamel and surfaces, headaches and jaw joint (TMJ/TMD) pain. We offer a variety of treatments that are designed for different age groups – including adults.

The new techniques and appliances we use greatly reduce discomfort levels, decrease the frequency of visits, shorten treatment time and may allow you to choose from several different types of braces. Your choices may include metal braces, translucent braces, or transparent aligners that can be worn to improve mild cases of misaligned teeth.

Over 25% percentage of our patients are adults, and they agree that it’s never too late to improve their greatest asset — their smile. Contact us about adult orthodontics today.

Common Orthodontic Problems

Common Orthodontic Problems

protrusion image needing braces or invisalign from orthodontist pat cusack in peoria il Upper Front Teeth Protrusion

The appearance and function of your teeth are impacted by this type of bite. It is characterized by the upper teeth extending too far forward or the lower teeth not extending far enough forward.

overbite image needing braces or invisalign from orthodontist pat cusack in peoria il Overbite

The upper front teeth extend out over the lower front teeth, sometimes causing the lower front teeth to bite into the roof of the mouth.

crossbite image needing braces or invisalign from orthodontist pat cusack in peoria il Crossbite

The upper teeth sit inside the lower teeth, which may cause tooth stratification and misaligned jaw growth.

openbite image needing braces or invisalign from orthodontist pat cusack in peoria il Openbite

Proper chewing is impacted by this type of bite, in which the upper and lower front teeth do not overlap. Openbite may cause a number of unwanted habits, such as tongue thrusting.

crowding image needing braces or invisalign from orthodontist pat cusack in peoria il Crowding

Crowding occurs when teeth have insufficient room to erupt from the gum. Crowding can often be corrected by expansion, and many times, tooth removal can be avoided.

spacing image needing braces or invisalign from orthodontist pat cusack in peoria il Spacing Braces Peoria IL invisalign.

Spacing problems may be caused by missing teeth, or they may only be a cosmetic or aesthetic issue.

 dental midlines image needing braces or invisalign from orthodontist pat cusack in peoria il Dental Midlines not Matched

This type of problem is caused when the back bite does not fit and match appropriately, which may negatively impact jaw and proper dental function.

thumb sucking image needing braces or invisalign from orthodontist pat cusack in peoria il Thumb Sucking Habit

This common habit will flare the top teeth forward, tip the lower teeth back, and create a narrow upper jaw shape that can put the back teeth into a crossbite.

tongue thrust image needing braces or invisalign from orthodontist pat cusack in peoria il Tongue Thrust Habit

Normally the tongue pushes against the roof of the mouth when a person swallows. Sometimes, however, a person can develop a habit in which the tongue pushes forward against the back of the front teeth when they swallow. This undesired habit will create an open bite in the front.

Types of Braces

Types of Braces

metal braces image from orthodontist pat cusack in peoria il Traditional Metal Braces

Traditional metal braces are the most common type of braces and are more comfortable today than ever before. Made of high-grade stainless steel, metal braces straighten your teeth using metal brackets and archwires. With metal braces, you have the option of adding colored elastics (rubber bands) for a more unique and colorful smile.

ceramic braces image from orthodontist pat cusack in peoria il Ceramic

Ceramic braces are made of clear materials and are therefore less visible on your teeth than metal braces. For this reason, ceramic braces are used mainly on older teenagers and adult patients who have cosmetic concerns. While they are visually less prominent, they do require more attention to oral hygiene as ceramic braces are larger and more brittle than their metal counterparts. For these reasons, ceramic braces tend to be used more on upper front teeth than on lower teeth.

invisalign teen image from orthodontist pat cusack in peoria il Invisalign®

Invisalign® uses a series of invisible, removable, and comfortable aligners to straighten your teeth. Not only are the aligners invisible, they are removable, so you can eat and drink what you want while in treatment. Plus, brushing and flossing are less of a hassle. The aligners are comfortable and have no metal to cause mouth abrasions during treatment.

self ligating braces image from orthodontist pat cusack in peoria il Self-Ligating Braces

Self-ligation is a system of braces that can potentially shorten treatment time, be more hygienic, and allow for decreased tenderness during treatment. It is made from stainless steel or ceramic for stability and is smaller in size for aesthetics (great for our adult patients.) The rounded structure improves patient comfort while maintaining overall performance. Self-ligation uses lighter wires and lower friction brackets to move teeth, resulting in slightly faster treatment times due to its sliding mechanism designed to maximize tooth movement speed and efficiency.


retention after braces image from orthodontist pat cusack in peoria il


Once the active orthodontic appliances are removed, the patient will receive retainers to stabilize the dental correction. Because the bone and soft tissues surrounding the teeth are stabilizing for several months after braces are removed, it is imperative that the retainers are worn as instructed. Failure to wear the retainers may result in undesirable movement of the teeth, which could necessitate re-treatment. Braces Peoria IL invisalign.

Our goal is to help your smile stay beautiful and healthy for a lifetime. Your cooperation is essential in order to achieve this goal.

Your New Braces

Congratulations! You’ve taken the first step in an amazing and life changing experience, so now what? Here are some helpful tips.

braces peoria il child brushing teeth from orthodontist


Brushing With Braces

You will notice it is harder to keep your teeth clean with orthodontic appliances. Food can easily become caught in the brackets and between your teeth. Proper brushing and flossing is vital to keeping your teeth and gums healthy, and is essential in preventing the development of stains, cavities, or gum disease. Dr. Cusack recommends brushing when you wake up in the morning, before bed, and after every meal. In addition, use a fluoride and/or anti-bacterial mouth rinse after brushing to keep teeth strong and healthy. Additional hygiene tools, such as electric toothbrushes and Waterpiks, may help out if you need more than a conventional tooth brush and floss.

To brush your teeth, start by brushing the outer surfaces of the teeth and braces with a gentle, circular motion. Tilt your toothbrush 45 degrees to clean the top and bottom of the braces. Concentrate on the areas of your teeth between the gums and the braces, as this area is most commonly missed when brushing. Then, brush the chewing surfaces of your teeth as well as the inside surfaces of your teeth. Don’t forget to brush your tongue as odor-causing bacteria can get trapped here. Do not brush with a hard-bristled toothbrush or use harsh, saw-like motions. This may cause damage to your teeth and gums by wearing away the surface structure of the teeth.

To clean between the brackets, use an interproximal or proxy brush, which is a small, pine-tree shaped brush that can be adjusted to different angles. Dr. Cusack will provide a proxy brush in the “orthodontics survival kit” you will receive, but they can also be found at most drug stores. Insert it under the arch wire, and gently work it in an up and down motion. By doing this, you will be cleaning the surfaces of your teeth to the left and right of the braces. Do this between all of your brackets and bands.

There are 10 rules of hygiene during orthodontic treatment to ALWAYS remember:

  • Brush after EVERY meal, and AT LEAST 4 times a day.
  • Floss EVERY DAY.
  • Brush every surface of your tooth.
  • Brush every surface of your braces, including in between. Brush your gums, and concentrate on the ones between the teeth and braces.
  • Brush in a circular motion.
  • Brush your tongue.
  • Rinse with fluoride-fortified mouthwashes.
  • A Waterpik is a great cleaning tool.
  • It only takes one day of improper cleaning to cause BIG problems!


flossing with braces in peoria il from orthodontist pat cusack


To clean between your teeth, you will need to floss. Several different flossing tools have been developed to assist orthodontic patients with this, as it can be difficult to stretch the floss underneath the orthodontic wire.

Please watch this short video to learn about the "parts" of your new braces.



Unlike regular dental emergencies such as a tooth ache or a chipped/broken tooth, orthodontics has very few emergencies that can’t be handled with help from a parent, spouse or friend. As long as you are not in great pain or bleeding you should be able to attend to your own “emergency” in the comfort of your own home.

A loose bracket that is still affixed to the wire can be secured with wax until it can either be replaced or removed from the wire at your next appointment. A long wire that is ‘pokey’ can be bent away from your gum tissues with an eraser from a pencil or by using a spoon. Gently use the eraser to push the wire towards the teeth and place some wax over the sharp point. This is the only time you are allowed to put a pencil near your braces!

A wire that cannot be moved can be clipped with a sharp pair of nail clippers; just make sure you clean the clippers with rubbing alcohol and rinse them under water before use. Clip the wire behind the next bracket that is still securely fastened to your teeth. A lost elastic or tie wire can wait until the office reopens or your next appointment where the broken wire will be replaced.

In the case of any change to your orthodontic appliances we ask that you call the office when we re-open and allow us to make the decision regarding a return emergency visit. If you have bleeding, swelling or are experiencing extreme discomfort please call our office as soon as possible. Dr. Cusack’s cell phone number is on our answering machine if the office is closed.


Foods to Avoid

Hard and sticky foods can break off brackets, bend wires, and loosen bands, which will extend your total treatment time. Foods high in sugar can cause cavities, calculus build-up, and ugly, permanent stains on your teeth. So what can you do? Limit your diet to softer, healthy foods.

Here are some examples of foods that must be avoided during orthodontic treatment:

Hard Foods

Ice, nuts, popcorn, peanut brittle, rock candy, apples and carrots (unless cut into pieces,) corn on the cob, hard pretzels, hard rolls, bagels, hard tacos and corn chips.

Sticky Foods

Hard, sticky candy such as Jolly Ranchers, caramels, bubble gum, taffy, suckers, chewy candies such as Starburst, Dots or other jelly candies.

Chewy Foods

Pizza crust, crusty breads, beef jerky, gummy bears or gummy anything.

Sugary Foods and Drinks

Cake, ice cream, cookies, pie, candy, soda pop, and drinks with sugar. Also, do not chew on pens, pencils, fingernails or other hard objects. Please use your common sense when deciding which foods you should eat and those to be avoided. Remember, eating the right foods will provide you with the shortest treatment time possible!

What foods can I eat?

When braces are first placed or after an orthodontic adjustment, your teeth will be sore when you chew. Stick to soft foods such as soup, pasta, pancakes, eggs, macaroni and cheese, yogurt, Jell-O, milkshakes, etc. Or you can always eat Dr. Cusack’s personal favorite – mashed potatoes. After a few days, you'll be eating a pretty normal diet again.

For some contact sports, we recommend using a mouth guard that allows tooth movement to continue while protecting the skin tissue from getting impinged in the braces from hits to the head.  Never use the boil and bite mouth guards with braces as your braces may get stuck when you bite into the mouth guard. Dr. Cusack has mouth guards at his office or you can buy them at sports stores.

Musical Instruments

Musical Instruments

Dr. Cusack informs his instrument-playing patients that woodwind players may have slightly more difficulty than brass instrument players. Every musician seems to adapt very well to playing with braces after a week or two of practice. Some of them find that placing wax on the brackets is helpful during the initial adjustment period. If a patient is a “First Chair” player, some extra practice will ensure that they are conditioned to playing with braces and maintain that high level.



Retainers are made of a thermoplastic material that is sensitive to excessive heat, so they should be kept away from heaters, dishwashers, car dashboards or any place where the temperatures exceed 115 degrees(F). The retainers should be cleaned before and after placement in the mouth. Because the material used for fabrication is slightly porous, plaque tends to cling to the surfaces of the retainer. Gentle scrubbing with a toothbrush and a mild liquid soap will remove the plaque. A denture cleaning solution, such as Efferdent, will aid in the removal of plaque and tartar. Be sure to rinse the retainer thoroughly after cleaning to remove any cleanser residue.

Here Are A Few Things to Remember During the Years of Retainer Wear:

  • Don't fold it in your napkin or leave it on the table at a restaurant. Garbage cans don't make happy hunting grounds.
  • Don't put your retainer in your pocket. You might sit on it and break it.
  • Take your retainer out when swimming in a lake or ocean. If it falls out you may not be able to find it. The same goes for a swimming pool depending on the size of the pool.
  • Animals and younger children love to play with it. Please make sure your retainer is in your mouth at all times. Your retainer should only be out of your mouth when brushing or eating.
  • Your lower retainer may be a fixed retainer bonded onto your teeth. It is not considered permanent and can be broken or detached from your teeth, if you are not careful with it.
  • Bring your retainers to your check-up appointment. If anything happens to your retainers (i.e. it doesn't fit, it's broken, or it's lost) please call us ASAP. If your lower bonded retainer wire comes out, keep it and bring it in at your next appointment for rebonding.
  • The first set of retainers is included in your treatment fee. Any repair, replacement of your retainer, or rebonding of your lower retainer will be additional and charged to your account.
  • Keep things clean! Be sure to brush your teeth without your retainers in. Do not boil your retainer or put it in hot water. Brush your retainer with a toothbrush using toothpaste or water.
