They are the best! Worked with and made a fun experience with my son who is on the spectrum. We left with smiles and will definitely return!

My experience with the family at Bite Size Dentistry was phenomenal.
Dr. Moynihan and his staff was very welcoming. They addressed all my questions and concerns and more. Bite Size Dentistry don't treat you like just another patient, they treat you like family. I AM proud to say my children and I are part of the Bite Size Dentist Family.

We recently visited this office in nantucket with our 4yr old daughter. We had a great experience. Dr. Stewart was very attentive, and patient with her. The staff was also great with us, they do not only offer pediatric they also have adult and orthodontic. I highly recommend this place. We will be coming back.
Thank you so much for your services in the island.
