Our team takes pride in treating each patient as if they were a guest in our home. Our practice has a family atmosphere and we will always treat you and your child as well as we would treat our own. We understand that you are the reason we are here!

Our Qualifications

You can expect a unique combination of art, science, and experience. Dr. Catherine and Dr. Mark are board certified by the American Board of Orthodontics. This is the highest recognition given to orthodontists in the United States.

You can expect more than just straight teeth from our office! Our emphasis is on creating a bite where the teeth are working in harmony with the jaw joints and muscles for the best possible long term esthetics and stability.




Our Approach

We stay current with the latest technology, the best materials, and the leading-edge advancements in the specialty. So not only are you receiving top notch treatment, but we make it affordable. At our office, we focus on the details of ideal tooth position and the specifics of the bite relationship. We place attachments on all of the teeth (including the second molars), not just the ones you can see upon smiling. We invest in state-of-the-art equipment to continue to be a pacesetter in the profession.

Our goal is to combine dental and facial esthetics with a properly functioning bite that works in harmony with the jaw joints and muscles. Our objective is to provide a “Signature Smile” with long term dental health and stability.







Our Qualifications

Drs. Catherine and Mark are two of the very few orthodontic specialists who are certified by the American Board of Orthodontics. This is the highest degree of recognition given to orthodontists in the United States.

Drs. Catherine and Mark have completed the Roth-Williams course on Functional Occlusion, which emphasizes more than just straight teeth. The emphasis is on creating a bite where the teeth are working in harmony with the jaw joints and muscles. We focus on the details of tooth positions as well as the details of the bite relationship. We place attachments on all of the teeth (including the second molars), not just the ones that you can see upon smiling. We mount the study models of each patient’s teeth on an instrument called an articulator. This is a joint measurement that shows the exact bite relationship and allows for extremely accurate treatment planning.

Dr. Mark is currently a faculty member in the Department of Orthodontics at LSU School of Dentistry. Dr. Catherine was formerly on faculty as well and has recently retired after thirteen years of teaching. They are actively involved in the training and education of dentists specializing in orthodontics. They have also lectured on the national and international level and have published articles in scientific journals. Dr. Mark is on the Craniofacial team at Children’s Hospital in New Orleans, and he has treated hundreds of children with craniofacial deformities. They are actively involved in the development of new technologies in Orthodontics. Our office works with a number of companies around the world testing new products and techniques which allows us to stay on the cutting edge in the science of Orthodontics.

Drs. Catherine and Mark are committed to continuing education by continuous study of scientific literature, continuing education classes, and study-group involvement. We also host continuing education classes for the other dentists in the area.

Our schedule allows Drs. Catherine and Mark to spend quality time with each patient. We educate our patients using understandable language, and we are committed to keeping patients and parents informed about their orthodontic treatment and progress. We measure our success by long term results and long term relationships. In addition to cutting-edge orthodontics, we are forming lasting friendships.

Your time and convenience are important to us. We are proud to be an office where our patients are seen on time.

Is it safe to have an orthodontic consultation during this period of Covid?  

Yes, you are safe coming to our office.  We take all the necessary steps to ensure the safety of all patients and parents. As a small office we allow you to avoid the crowds normally found in large orthodontic clinics.

When should a child see an orthodontist?  

We recommend an orthodontic screening at 5 years of age to evaluate dental development and the facial growth pattern.

Should my child see Dr. Coreil if they still have “baby teeth”?  

Yes.  This is a critical time for tooth and jaw development and patients benefit from early intervention. 

Do I need a referral from a dentist to make an appointment with Dr. Coreil?  

Although we welcome referrals you do not need one to be a patient in our office.

You can call our office at 337-412-2134 or go directly to our website at coreilortho.com.

Can I get an opinion without an appointment?  

Absolutely!  Just go to coreilortho.com and click Virtual Appointment.  By providing photos to Dr. Coreil, we can answer many of the basic questions patients have about their condition.

What can I expect from the initial consultation?  

Every patient will receive a CT scan of teeth, jaws and airway allowing Dr. Coreil vividly demonstrate problems and treatment options.  Our patients also appreciate our use of videos to demonstrate why treatment is needed as well as how the treatment will be accomplished.

Will my teeth or jaws improve with age?  

No.  This is the reason that early intervention is the best way to address patient concerns.

Do problems with adult teeth slow down with age? 

No.  Crowding, tooth wear and periodontal health improve only with the help of a professional so do not delay your initial consultation appointment. 

How long will my orthodontic treatment last?  

Treatment time can range from 3 months to 25 months depending on needs and patient desires.  

 Can I participate in my treatment planning?  

We have a term Signature Smiles which means that our patients and parents are totally involved in planning the final smile.  We do not use one approach to treatment but instead make your treatment individualized for you.

How much does treatment cost?  

Cost will be determined by time in treatment.  Working with you we can make treatment affordable with in house financing and tailoring your treatment to your specific needs.

How frequent are appointments?  

In office appointments range from 6-8 weeks however we can also use Virtual Appointments so that your in office appointments can be as infrequent as every 4 months.

I live far away but want to come to Coreil Orthodontics, is this possible?  

We have patients living, working or going to school as far as Monroe and New Orleans.  Using our Virtual Appointment tool we can make you feel like you are next door.

 What is a Virtual Appointment? 

Whether you are a new patient or a current patient we can evaluate your status by simply taking a few photos of your teeth and face with a smartphone and Dr. Coreil normally responds to you within minutes from his iPhone.  Our patients love the fast response.

Does my child have to miss school for appointments?  

No.  We can utilize breaks for longer appointments normally completed in the morning.  We will work with you to satisfy both patient and parent.

Do I have to stay with my child during the appointment?  

No.  We are in the middle of the best shopping in Lafayette allowing parents to take advantage of this valuable time to get things done.

Do I need a dentist while in braces? 

Yes.  It is imperative that all of our patients maintain excellent dental health during treatment.

You will need to avoid hard foods but we allow patients to chew gum and provide a list of fun foods that they can eat while in treatment.

What happens if my braces break?  

No worries.  We are available 7 days a week to care for your needs.  Many patients send photos to Dr. Coreil and he guides them on how to fix the problem over the phone.

Can I call Dr. Coreil anytime?  

Absolutely.  Every patient has Dr. Coreil’s cell phone number and can reach him with questions or concerns.

Does my child need braces a second time if they had early treatment?  

Most patients choose to undergo a second phase of orthodontic treatment once all permanent teeth are in place for the best results.

When are expanders used?  

Palatal expanders are used to change the position of upper jaw bones thus providing improved function and additional space for permanent teeth.  

What is the best time to have an expander?  

We like completing expansion before age 9 for the best results and overall patient comfort.

Can I have an expander as an adult? 

Yes.  We expand many adults often with the support of an in office surgical procedure.  

Am I too old to wear braces?  

You are never too old.  Dr. Coreil has treated a number of patients in their 70’s and 80’s so don’t worry about being late.
