Donald Tsung-I Liu

Root canals don’t have to feel like a last resort. In Newark, endodontists specialize in saving teeth that might otherwise be lost—quietly, precisely, and with tools most general dentists don’t keep on hand. Donald Tsung-I Liu is one of those specialists, offering procedures that go beyond fillings and crowns to preserve what’s already there.

Omega Drive sits just off the main arteries that feed into Newark’s industrial edge, where warehouses give way to medical plazas. At 31 Omega Dr, the practice occupies a low-slung building that blends into the landscape; no flashy signage, just a nameplate and a door that opens to a different kind of dental care. The focus here is on the interior of the tooth—root canals, apicoectomies, and emergency treatments for abscesses or trauma.

Patients arrive with referrals or after a sudden crack reveals nerve exposure; they leave with a tooth that still functions, often without a crown. The work is methodical, relying on microscopes and digital imaging to guide tiny instruments through canals most people don’t know exist. When a filling isn’t enough or a crack runs deeper than expected, this is where the next step happens.

Directions are straightforward: map it once, then follow the curve of Omega until the numbers align. For questions or to schedule, call (302) 733-7600—no referral needed, though most patients arrive with one already in hand. It’s the kind of place you hope you won’t need, until the moment you do.
