About Nicholas M. Mastroianni D.D.S.

Routine cleanings and unexpected toothaches don’t wait for a convenient moment. Nicholas M. Mastroianni D.D.S. handles both on Maple Avenue, where the sidewalks stay swept and the shade from old oaks stretches long in the afternoon. The practice sits at 23 Maple Ave, Greenwich, CT 06830, a short walk from the post office and the town’s quiet side streets.

Dental care here covers everything from fillings and crowns to emergency extractions and simple cosmetic tweaks. Patients also find root canals, periodontal treatments, and pediatric check-ups on the schedule. When the calendar opens up, a call to (203) 900-2220 secures a slot; the same number works for last-minute cancellations or urgent pain that can’t be ignored.

Greenwich’s tree-lined blocks make parking simple, and the map keeps the address easy to spot. For directions, pull up the link: here. If the tooth starts throbbing on a Tuesday, this is where the town sends you.
