An orthodontist is a dental specialist who has undergone additional training in orthodontics and dentofacial orthopedics. They’re experts in diagnosing, preventing and treating malocclusions, which are problems with the spacing, positioning or alignment of the teeth and jaws. Orthodontists use appliances, including braces and Invisalign®, to straighten the teeth, align the jaws and give you a smile that looks, feels and functions at its absolute best!
