General Dentistry

At Sag Harbor Dental we offer modern general dentistry procedures to correct all your dental problems. Our experienced staff works together as a team to provide you with tooth-colored fillings, crowns and bridges, root canals and tooth extractions in order for you have a great smile.

Cosmetic Dentistry

If you are concerned about the appearance of your smile, then worry no more! We offer the latest cosmetic dentistry procedures available to meet all your unique needs, including porcelain veneers, teeth whitening, cosmetic bonding and dental implants. A dazzling, picture-perfect smile is closer than you think!


In addition to dental treatment, we offer orthodontic care using Invisalign. Invisalign is the clear way to straighten teeth without braces, using aligners. The aligners are removable and virtually invisible, which means you can straighten your teeth without anyone knowing; and you can still eat and drink what you want.



State-of-the-art CAD/CAM technology provides us with extremely precise digital models that we use to create highly accurate dental restorations. Learn More
