Orthodontics For Children and Teens

Early orthodontic treatment benefits children by addressing issues early and preventing more complex problems later. We create customized plans for children and teens to achieve a healthy, confident smile.

Airway Orthodontics

Our Airway Orthodontics treatments focus on improving breathing, sleep quality, and facial development by addressing underlying jaw and airway issues. Using advanced airway-focused orthodontic techniques, we help support proper jaw growth, enhance airflow, and promote long-term oral and overall health.

Adult Orthodontics

No one is too old for orthodontic treatment! Adults often seek orthodontic care for the same reasons as children. Some couldn't address issues in childhood, while others need follow-up treatment due to relapse or previous limitations.

What Sets Us Apart

Leslie Lynch
We have had such a great experience at Total Orthodontics. My kids have seen Dr. Barefoot and Dr. Donahue and they have loved both of them. Everyone in the office is so friendly. My daughter is 9 and has already been in for a consultation and is excited to get braces on in the future!
Danielle Thompson
We’ve had two kids go through the TO practice and both times we’ve had a great experience and great service. We appreciate the convenience of having two different locations so we can choose which one works best for our schedule. Their teeth also look great! Our oldest daughter gets so many compliments on her smile. Our youngest daughter is just getting her braces off today, so I’m sure she will get the same compliments.
Kjrsten Hefty
My 10 year old son had such a great experience here, and the smile to prove it! The doctors and staff are wonderful.
Allison Barrett
My teeth have been super problematic from an early age and you wouldn’t even be able to tell now after getting treatment. The doctors are super thorough and walk you through each step of the process. I am so happy with my results and wouldn’t have my smile any other way.

I just retired, after working at TO for 16 years as a Treatment Coordinator. I was always amazed at how many people transferred into our office from another local orthodontist, because they were unhappy with their care. Trust me, this did not happen the other way around. Working at TO is something employees in the tight-knit dental community covet and I was proud to work there!

Teresa

My twin boys and my wife were all treated at TO. We couldn't be happier with the results. Dr. Theroux and Dr. Barefoot made the whole experience fun and pleasant. Comedians and excellent orthodontists! I tell my wife and twins it looks like they just stepped out of a toothpaste commercial. They should be teeth models.

I trust and value the exceptional care that TO provides to both my patients and my family. Dr. Theroux and Dr. Barefoot, as board-certified orthodontists, deliver outstanding results. The staff at TO radiates happiness at every visit and are committed to helping children and adults achieve beautiful smiles. On top of that, they provide opportunities for their patients to give back to the community through meaningful service projects, putting those beautiful smiles to good use—an invaluable gift to each of their patients.

Pediatrician, Academy Park Pediatrics

8 members of our family have been treated by the team at Total Orthodontics! Through the years , we have been thrilled with our results and love this office. As a Pediatrician , I refer all of the kids in my practice for care at TO. 

Dr. Michael Milobsky

Pediatrics at the Meadows

Total Orthodontics has served both my family and pediatric patients with honest and conservative treatment for decades.  The feedback I received from my patients for over twenty years has been excellent.  The entire TO Smiles team made the orthodontic process pleasant. Also, Drs. Theroux and Barefoot have their TO Smiles program that provides free orthodontic treatment and free pediatric dental care to children who would otherwise be unable to afford it, a necessary and much needed outreach to the community.  They are the best!

I can't say enough wonderful things about this practice.  We work hard in our office to provide excellent treatment, and we care about our patients as people first and look for specialists who will give our patients the same top notch care.  We have oodles of orthodontists to choose from, but we’re looking for the whole package - exceptional treatment from doctors who care and a fabulous staff to boot.  The team at Total Orthodontics never disappoints.
