Dr. Ioana D. Piersall, DMD

Frederick’s dental scene has a quiet corner on Thomas Johnson Drive where routine cleanings and urgent repairs share the same schedule. Dr. Ioana D. Piersall, DMD keeps the office at 198 Thomas Johnson Dr #20, a low-slung suite tucked between a dry cleaner and a tax prep storefront. The strip is the kind of place locals drive past daily, yet most can’t name every tenant—until a chipped molar or a throbbing abscess demands attention.

General dentistry here covers fillings, crowns, and root canals, while preventive visits include digital X-rays and periodontal screenings. When a tooth can’t be saved, extractions are handled in the same chair, and clear aligners are fitted for adults who want straighter teeth without metal brackets. The practice also offers teeth-whitening treatments for patients who prefer to brighten their smile between check-ups. Questions or appointment requests can be made at (301) 695-6001 during weekday hours.

After the last rinse, patients step back onto the sidewalk where the scent of fresh bread from the bakery next door competes with the antiseptic tang of the clinic. A short walk leads to Baker Park, a reliable spot to sit and let the Novocain wear off before driving. For directions, the map is here.
