Becca
It’s never too late to have orthodontic treatment. I thought it was passed that stage, I never had braces as a kid or teen. As I turned 30, I was excited I could straighten out my teeth.
Bella
My favorite thing about OX is how they treat you and how nice they are here. I love the staff members.
Lauren
I’d say that it’s the perfect place, you feel like you are apart of the OX family.
Camille & Deandra
It’s very easy, we change them out a couple of times a week.
