About River Valley Dental Dr Mark R. Bydalek, DMD, Dr Andrew H.Tang, DMD

Even in Hunterdon County’s patchwork of farms and forests, dental needs don’t take a season off. River Valley Dental keeps a steady chair open for the usual suspects—exams, cleanings, fillings—along with a few surprises. Crowns, root canals, and tooth-colored fillings sit next to simple night guards, aligning with what the road schedule demands.

Find the practice tucked above the valley floor at 528 Rosemont Ringoes Road in Sergeantsville, one long two-lane from Lambertville. The building sits back from the blacktop, tucked among maples that pop orange come October. Unless you’re headed to the state park or the regional trailhead, you might drive right past without realizing the office is there.

Old-school phone etiquette still applies: call (609 397-8833) and let them slot you between the morning bridge traffic and the afternoon school runs. No frills, no waiting for paperwork—just the kind of exchange that used to feel normal before every portal asked for an email and a password.

A ten-minute jog east lands you in Stockton’s artisan row if you want to stretch your legs after an appointment. Or stay local: Sergeantsville’s one traffic light still knows how to hold a conversation across the street. Grab a coffee at the general store and watch the valley settle into quiet—proof that slow isn’t the same as idle.
