Best reception from a new patient standpoint and impressive care with up to date skills methods and execution. Everyone makes you feel comfortable and their number one priority. Love my dental team. Randy H. Belmont, NH

My husband and I have been going to Northborough Dental for over 15 years. Both the doctors and staff are terrific. However, I've been bringing my 96-year-old mother to them for the past 7 seven years and I can't say enough how absolutely wonderful and caring and sensitive they are with her! They are truly terrific! Shannon K. Belmont, NH

Providing Dental Care

To Northborough

Enjoying a healthy, confident smile is a lifelong commitment, and our team partners with patients to work together towards this goal. We strongly recommend scheduling dental checkups and cleanings for all members of the family at least twice per year. This allows our doctors to pinpoint any concerns as soon as possible to ensure they do not require more involved treatment down the line.

Tooth Replacements

The loss of natural teeth can make it difficult to eat your favorite foods, smile in photos, and ultimately feel self-confident daily. Thankfully, dental implants can seamlessly turn back the clock and give you a smile that is beautifully complete. This modern service replaces the entire natural tooth, providing much-needed durability in addition to excellent aesthetics. At Northborough Dental Associates, we place and restore dental implants in one convenient location.
