With two office locations in North Bethesda, MD, and Washington DC, Potomac Dental Center combines state-of-the-art technology with sensitivity to patient needs to provide you with the best possible dental care. Under the supervision of Dr. Elenir Bernardes, doctors and staff work hard to achieve their goal: giving every patient a bright, healthy smile. At Potomac Dental Center we want you to be comfortable. For nervous or sensitive patients we provide nitrous oxide (laughing gas). With as little as one trip, you can start your journey toward a happier, healthier smile.
