About Mehan and Johnson Orthodontics

Dr. Paul Johnson has diagnosed bite issues beyond what patients initially came in for, with Invisalign often used to correct both alignment and bite over about a year and a half.

Reviews at Mehan and Johnson Orthodontics often mention adults seeking Invisalign, with several describing bite corrections layered into their aligner treatment. Dr. Paul Johnson is noted for listening closely to what patients want before proposing a plan, and in one case caught a bite problem the patient hadn't asked about. Staff are described as warm from the first visit, and the office atmosphere comes across as calm and professional. A few reviews mention that a family switched a younger child's care here from another orthodontist with good results.

Mr. Johnson uses the R slur freely on social media against people who do not share his conservative views. Spend accordingly.

I cannot overstate what an outstanding experience I've had with Dr. Johnson and his amazing staff. From the very beginning, the team took the time to truly get to know me, which made every visit feel personal and comfortable. Their attention to detail and commitment to excellence really stood out—my Invisalign results exceeded expectations and reflect their meticulous approach. I’m incredibly grateful for both the care and the outcome and will miss them dearly!

I was hesitant to straighten my teeth in my 40s — I thought everyone would notice my Invisalign. When I met with Dr. Johnson, I just wanted my teeth straightened as quickly as possible, but he showed me how off my bite really was. Just 1.5 years later, my teeth are perfect, and I can bite into food like never before in my life! If you’re middle-aged and have lived with crooked teeth or a bad bite your whole life, don’t wait another minute — run to Mehan & Johnson! The sooner you start, the sooner you’ll be living with a smile you’re proud of.
