Welcome to PDA Dental Group

For 50 years, the PDA Dental Group has provided dental care to generations of families in Winchester, Reading, and surrounding towns in Massachusetts. Creating caring relationships with our patients and connecting with our community in the greater Boston area, we have built a strong reputation for high quality oral healthcare. Our success in treating children and our reputation has allowed us to expand beyond pediatric dentistry to include orthodontics and adult dentistry — treating families from infancy to adulthood.
