Patients Love Us!


I needed retainers after completing treatment somewhere else, and they welcomed me without any hesitation. The fitting process was smooth, and they explained how to care for them properly. The retainers fit perfectly from day one.

Orthodontic Specialists of Oklahoma goes above and beyond to not only ensure you are getting the proper treatment , but they want to make sure you have all financial resources available to you too.The staff is genuinely caring and supportive and provides the same high level of care and attentiveness at each and every appointment. 😁🦷🪥

My daughter has been coming here for braces for almost a year now and the confidence difference has honestly been incredible to watch. Before treatment, she avoided smiling in photos because she hated the gaps between her teeth. The staff here has been consistently patient and kind during every appointment, especially during the first few visits when she was nervous about pain. One afternoon the office got extremely crowded and appointments started running behind, but the front desk communicated clearly instead of pretending nothing was happening. That level of respect really matters to parents. Her teeth already look so much straighter and she recently smiled openly in a family picture for the first time in years. Seeing that change alone made the entire process feel worthwhile for us.

Had my Invisalign done yesterday and I seriously cannot say enough good things about Amy. From start to finish she was so friendly, patient and made the entire process feel easy and not overwhelming at all. She explained everything so clearly, gave me so many helpful tips and genuinely took her time with me, you can tell she truly cares about her patients. Her energy was so comforting and positive, which made a huge difference. Absolute top tier experience. Amy is AMAZING and I’m so thankful for all her hard work 🤍✨
