Kevin J O'Neill Inc

Endodontics is one of those specialties people hope to never need. Kevin J O'Neill Inc focuses solely on root canals, retreatment cases, and diagnosing tooth pain—no general dentistry, no distractions. The practice operates out of a professional plaza in Roseville, tucked just off Sierra College Boulevard at 10 Sierra Gate Plaza #190. It’s a quiet corner of the city, far from the bustle of the Galleria but still central enough for easy access.

Google’s lone review gives it a perfect score: 5.0 from 1 rating. That single data point doesn’t tell a full story, but it does signal someone left satisfied. Endodontists often fly under the radar until an emergency strikes—sudden pain, a failed filling, or an abscess that won’t wait. This isn’t the kind of office you’d book for a cleaning or whitening. It’s where you’d end up if a general dentist refers you for something deeper, like cracked teeth or complex canal anatomy.

Most patients arrive with one goal: relief. The phone line, (916) 786-3303, connects directly to the practice, skipping the layers of a larger clinic. No online booking portals, no chatbots—just a straightforward number for appointments. That simplicity might appeal to someone dealing with urgent discomfort, though it’s wise to confirm hours before calling. Roseville’s sprawl means traffic can vary, so timing matters if you’re coming from Rocklin or Citrus Heights.

The map listing pins the location near the intersection of Sierra College and Eureka Road, across from the auto dealerships. If you’re navigating there for the first time, the plaza’s numbering can be subtle—look for the #190 sign near the upper level. One visit is usually enough to hope you’ll never need another.
