Dr. Sean O'sullivan

Routine cleanings and unexpected toothaches don’t wait for convenient moments. When they happen, having a dentist nearby who handles everything from fillings to crowns can save a trip across town. Dr. Sean O’Sullivan covers those basics and more right off Old Westminster Pike, where the rolling hills of Carroll County start to flatten into the suburbs.

Beyond the usual check-ups, the practice offers root canals, extractions, and even cosmetic work like whitening or veneers—so whether it’s a chipped tooth or a full smile makeover, the options are all under one roof. The office sits at 531 Old Westminster Pike Suite 100-101 Westminster, MD 21157, tucked between a hardware store and a small insurance agency, making it easy to combine with other errands.

Dental visits aren’t always fun, but they’re simpler when the drive is short and the parking isn’t a scavenger hunt. Westminster’s mix of farmland and subdivisions means traffic rarely backs up here, and the area has enough cafes and pharmacies to turn a dental appointment into a low-key outing. Directions are straightforward if you’re coming from downtown or the outskirts—just follow the map here.

Most people call ahead to book, and the number hasn’t changed in years: (410) 857-5700. If you’re new to the area or just switching dentists, it’s the kind of place where you can walk in with a cracked molar and walk out with a plan—no extra drama, no extra miles.
