About John B Harrison DDS MSc

Dr. Harrison is described as declining unnecessary treatment, from skipping a $4,000 Invisalign upsell to telling one patient braces weren't needed at all.

Reviews describe Dr. Harrison handling complex cases, including jaw issues and gaps that persisted after prior braces elsewhere, and correcting bites alongside straightening teeth. A recurring theme is restraint with treatment recommendations and pricing: several reviews note transparent costs and no push toward add-ons like Invisalign when not needed. Families with multiple children in treatment and adults returning for braces later in life also describe positive experiences, along with a kid-friendly office at two locations.

He is well knowledge, simple and transparent. The dentists with big heart and full of common sense are rare lately. My little son previous appointment with other dentist " need to remove 11 teeth in hospital for 6K otherwise he has chance to lost his vision", put myself in panic mood like I got only 1 choice. I was questioning myself, he is 6 and his teeth aren't that bad so I made appt with Dr Harrison to double check. He is so helpful and told me only need 1 teeth to be removed today with other dentist, my son will lose his teeth anyway, and see him in 6 months. I will trust Dr Harrison opinion from now on.

Dr. Harrison is truly the best orthopedic specialist I’ve ever had the pleasure of meeting. His expertise is unmatched. From the very first consultation, he made me feel heard, valued, and completely at ease. His calm confidence, clear explanations, and genuine compassion are incredibly rare. Every step of the way, Dr. Harrison showed remarkable patience, answering all my questions with kindness and never rushing through appointments. His dedication to his patients is obvious — you can tell he truly cares, not just about your recovery, but about you as a person. Thanks to him, i can smile wide with confidence. Made my insecurities with my teeth go away forever. I have so many good things to say about him — he’s not only a brilliant orthopedic, but also one of the most thoughtful, humble, and down-to-earth people I’ve ever met. If you’re looking for someone who combines skill, heart, and integrity, Dr. Harrison is the one.

Being introduced to Dr. Harrison by my mom, who is a current patient was, he is hands down the best orthodontist that I've ever seen. I had gone to several orthodontists, including Aspen Dentistry for a quote on Invisalign and was told that my teeth have "shifted up" and that I need to invest $4,000+ in Invisalign. The biggest deal breaker with Aspen was them telling me that if I don't invest now, my teeth would crack and Invisalign would be cheaper than the implants that I would surely need to buy at some point. Dr. Harrison reviewed my chart and not only disagreed with their pricing and pressure tactics, but it turns out that I don't even need treatment! I would have spent $4,000+ on something that I don't even need to meet the quote of a large corporations. If you want straightforward, professional, and empathetic treatment, you will be hard-pressed to find someone better than Dr. Harrison and his staff.
