Specializing in Smile Transformations


Dr. Kothari is a certified specialist in orthodontics, which means he completed two more years of specialty training in an orthodontic residency program after finishing dental school. As a Tarrytown orthodontist, he’s an expert in diagnosing, preventing and treating malocclusion, or issues with the size, shape or position of the teeth and jaw. He does this using special appliances, including braces and clear aligners. At 914 Smiles, he helps children, teens and adults get the healthy smiles and aligned bites they deserve.
