We have a wonderful pediatric dentist, whom other practitioners have told me may be the best in the state. He is located in Waltham, however. His name is Dr. John Caravolas ( he works with his cousin, who also has the same last name. So if you call, be sure to tell them you want "Dr. John".). Phone number: ###-###-####. My kids, now 9.5, have been going to him and his associate, Dr. Cara, for about 6 years. They have no fears, put up no fuss, and come out smiling every time.
Be sure to check out whomever you choose. Good luck!
