At Pediatric Dental Associates Dental Group, we create an environment where your child feels safe and comfortable—and can even have fun! We work to ensure that our young patients have a positive experience, from their very first visit. Our pediatric dentists have specialized training in the treatment of infants, children and adolescents. Together with our staff members we make children feel at ease in the dental office.
We have been working with children and their families in Winchester and Reading for 40 years. Originally a strictly pediatric dentistry group, we have been able to expand our practice to orthodontics and general dentistry thanks in large part to the loyalty of our patients. We are proud to serve Boston-area families from infancy to adulthood.
