Dr. Mark Slovin, DDS

On Nassau Avenue, Dr. Mark Slovin, DDS keeps a steady presence among the strip’s mix of shops and cafés. The block runs from small businesses into residential side streets, offering a quiet corner for routine care. A single-floor office occupies the second unit inside a two-story building, marked by a modest storefront sign.

Inside, general check-ups share space with specialized services. Crowns, bridges, and tooth-colored fillings blend with preventative cleanings and night guards for grinding. Children often arrive for sealants or fluoride treatments, while adults schedule root canals or periodontal maintenance. The practice handles emergencies too, though no specific time slot is guaranteed.

For an appointment or after-hours advice, dial (631) 581-0417 and leave a message if the line is busy. They return calls the same day whenever possible. Walk-ins are taken when slots open, but calling ahead ensures a smoother visit.

After turning off Commack Road, turn right onto Nassau; the entrance sits two doors past the florist. Pull into the small lot behind if spaces are open, or use the angled curb spots along the avenue. When the storefront blends with the late-afternoon light, you’ll find the office number posted above the buzzer. Check the map for real-time traffic before you leave.
