Since 1993, Mary Beth Dunn, D.D.S., has been treating children in the Williamsville, New York, area. In fact, she has more than three years of Advanced Pediatric Dental Education/Clinical Training at the Women and Children's Hospital of Buffalo, beyond her dental school education. This expertise results in superior pediatric dental care within a gentle, caring, and fun atmosphere. Our staff knows your time is valuable. For this reason, we see patients by appointment only and recommend early appointments for younger children. When you are unable to make your appointment, we ask that you provide us with a 48-hour notice. We'll be happy to reschedule.
