Dr. Daniel H. Choi, DMD

Endodontics isn’t the kind of specialty most people think about until they’re suddenly in need of one. Root canals, cracked teeth, or persistent dental pain often lead to a referral—and in Pleasant Hill, that might bring you to a second-floor office on Gregory Lane. The suite number, 200, is easy to miss if you’re scanning the building for the first time, but it’s there above the tree-lined streets of this quiet Contra Costa County pocket. No flashy signage, just a straightforward practice handling the kind of precise work that keeps teeth functional when simpler fixes won’t cut it.

Patient feedback on this practice is sparse but steady, with a 4.0-star rating from 4 reviews on Google. That’s not the volume you’d see for a general dentist, but endodontists tend to operate differently—most visits come via referral, and the focus is on resolving urgent issues rather than routine cleanings. Whether it’s a retreatment of a prior root canal, diagnosing tooth trauma, or addressing infections that linger beneath the gumline, the work here centers on what’s often the last line of defense before extraction. Pleasant Hill’s mix of suburban homes and low-key office parks means you’re more likely to find this place by searching than by stumbling upon it.

The area itself is a study in East Bay pragmatism: no tourist draws, just the kind of neighborhood where people live and work without fanfare. Gregory Lane sits near the border of Walnut Creek’s bustle but stays firmly in Pleasant Hill’s more understated rhythm. If you’re mapping out the visit, note that the office is a short drive from Highway 680, though you won’t find the kind of foot traffic that would make it a walk-in destination. Appointments here, like most specialty dental practices, are scheduled in advance—no drop-ins for something as precise as endodontic microsurgery or internal bleaching.

For questions about treatment options or to set up a consultation, the practice can be reached at (925) 363-3553. If you’re plotting the route, the map pinpoints the location just north of the Pleasant Hill BART station, tucked into a professional building that blends into the daily commute. No grand entrance, no frills—just the kind of place you hope to visit once and never need again.
