What sets us apart?
At Great Bay Orthodontics, we use cutting edge technology to ensure an exceptional, efficient treatment experience that suits your unique needs. By investing in best-in-class technology such as an Intraoral Scanner (no more goopy impressions!), digital X-rays, and 3D printed appliances, we are able to ensure a completely digital and minimally invasive experience from start to finish.

Giving Back
It’s safe to say our team loves the animals that make us smile, day in and day out. That’s why we’re proud to support The New Hampshire Society for the Prevention of Cruelty to Animals, a local non-profit organization on a mission to save the lives of companion animals through rescue, rehabilitation, and adoption. With every new patient that joins the practice, we donate back to the NH SPCA directly to help provide food, shelter, medical care, and other essential supplies to rescued animals seeking their forever home! Dr. Walsh and his family rescued their dog, Stella, and want every pet on the Seacoast to find the safe, loving family they deserve. We hope each appointment makes you smile knowing that Great Bay Orthodontics truly cares about every four- legged friend in our community!
