Our Reviews

From real patients like you

Cynthia Fine, BSDH

Dr Johnston provides excellent orthodontic care for my four children. All my children have complex cases that require advanced knowledge for proper orthodontic treatment. Dr Johnston has been courteous at all times and provides treatment options that are explained easily. Dr Johnston and staff are friendly and always patient when answering questions.



I switched to Dr Johnston after several orthodontist misdiagnosed my children’s orthodontic problems. I have a bachelors in Dental Hygiene and professionally I refer patients to Dr Johnston for their orthodontic needs. Having a correct “bite” or occlusion is the foundation of oral health and I don’t trust anyone else other than Dr Johnston for orthodontic care. He creates beautiful smiles! :)

Great warm, welcoming, and professional environment. Treatment plan set to accomplish exactly what we wanted for reasonable rates. Very impressed with the overall experience.

David Hebert

Dr. Johnston’s office has been a pleasure to work with since day 1. We just had our second son get his braces off and the results are beautiful. We highly recommend Dr. Johnston!

I started orthodontics with Dr. Johnson when I was in middle school and I am now out of college. My retainer recently broke after years of use so I paid Dr. Johnson another visit. It had been probably 7 years since I had been there and coming back felt like I’d never left. Dr. Johnson will of course make your teeth straight, but he will also care about you which makes all the difference in a doctor! His staff is also super sweet! If I could give him 6 starts I would. Seeing an orthodontist is expensive, but a confident lifelong smile is priceless!

Dr. Johnston has provided care for each of my three daughters. We have been nothing but thrilled with his professionalism and expertise. He is great with both kids (he has 4) and parents and takes time out to explain his treatment plan on an ongoing basis. We find his staff personable and spunky -- they are quick to put a smile on your face. They do an especially great job empowering their patients who are most often children. I've never seen a kid dreading to go back to their appointment. We feel most fortunate to have someone so close who is genuinely interested in the long-term care of my kid’s teeth. Thanks Dr. Johnston and Staff!!

Staff is fabulous and genuinely attentive to your needs and concerns. Dr. Johnston is always cheerful, and I see that he listens and actually hears the concerns of his patients, no matter how young. Oh.... And did I say my teeth and smile look great?

Michele Rhyne

Our family’s experience with Johnston Orthodontics deserves a 5-star rating! From Dr. Johnston’s treatment plan for braces for our twin daughters to my personal Invisalign outcome. His staff is always friendly and professional. My daughters have been in braces one time —- one and done —- due to Dr. Johnston’s thorough treatment plan and having a vision so they are not in and out of braces several times. I couldn’t imagine going anywhere else!

Holly Russell

So incredibly pleased with my Invisalign results!! My teeth have never looked better, and I would highly recommend this service to anyone who is even slightly considering it! Dr. Johnston and his staff are all attentive and truly skilled in this field!

Kristen Coleman

I would highly recommend Dr. Johnston and his staff. Two of my children got braces with him and even I decided to do Invisalign. All of our teeth look fabulous!!! His staff is very professional and courteous at all times.

Nicole Gordon

They are AWESOME. They have a waiting room for children with arcade games and a TV so that the children waiting will never get bored. They also have an adult waiting room where you can catch up on what you whatever you want to do or just watch the TV they have in there. They also have some kind of refreshments or food near the adult waiting room every morning. If you forgot your coffee or you want some tea, go right to the adult waiting room. It was AWESOME!!!!!!!!!!!

Elizabeth Sparling Wilson

Dr. Johnston and his staff are amazing. At this time, my 2nd sister is a current patient of Johnston Orthodontics. We are very happy with how her treatment is going. He also treated myself and my next sister. I am now 22. There was extensive work that needed to be done to get my teeth and jaw corrected. When my treatment was completed, my teeth were beautiful. I was voted 'best smile' in my high school senior class and represented the county of Davidson, TN in the Miss. Tennessee pageant. My second sister has Rheumatoid Arthritis in her jaw and her case was delicate. Dr. Johnston and his team were amazing with her condition and consulted with her Rheumatology doctor on her care. She as well was elected 'best smile' for her senior class. We have one more sister to go and I am confident Dr. Johnston and his associates will be as wonderful in her treatment as he was and is with the rest of us.
