Since 1986, Dr. Dennis Stiles has upheld the mission of delivering extraordinary care and service and offering individualized attention with detailed accuracy to his patients. Dr. Dennis J. Stiles DDS and his wife, Dr. Marie Tigani Stiles DDS, have been working together for over 32 years, serving patients in upper Montgomery County. Both doctors received their Doctor of Dental Surgery (DDS) degrees from Georgetown University School of Dentistry in Washington, DC.

Dr. Stiles serves on the LD Pankey Institute’s Board of Directors in Florida. He is proud to have been selected, trained and certified to offer Hybridge Dental Implants. Since 2008 Dr. Stiles has been a Dean’s Faculty member at University of Maryland School of Dentistry, where he enjoys teaching and interacting with dental students on a weekly basis.

The goal at Stiles Dentistry is to provide each patient with the highest quality of dental care in a gentle, caring and pleasant environment. The practice mission is to help patients keep all of their teeth, all of their life, and to enable patients to have a mouth that is comfortable, functional, healthy, esthetically pleasing, and is easily maintained through regular preventative visits and good home care.

Recognizing that some patients may feel anxious or apprehensive about receiving dental care, the doctors and team at Stiles Dentistry work hard to make sure that each person has a comfortable, positive experience. That’s why Stiles Dentistry is pleased to offer sedation dentistry for those patients needing a little extra comfort before receiving treatment. Feeling anxious about receiving dental care should never prevent anyone from having the beautiful, healthy smile they deserve.
