Our Commitment to You

As an orthodontist in Gaithersburg MD, we believe orthodontic treatment should be as simple, effective, and convenient as possible. That's why we utilize advanced digital orthodontics to help ensure treatment is safe, accurate and efficient. Our treatment methods are state of the art, and we've gotten rid of old, outdated practices like using dental putty to create impressions by replacing them with high-tech solutions like optical scanning technology.
