About Endodontic Associates: Jessy Tseng, DDS

Root canals and endodontic treatments often carry an unfair reputation—yet they’re a routine part of maintaining dental health. In San Mateo, specialists like Endodontic Associates: Jessy Tseng, DDS focus solely on these procedures, from diagnosing tooth pain to performing microsurgeries. The office sits on the fourth floor of 235 N San Mateo Dr, a building shared with other medical practices near downtown. With only three reviews so far, the current 3.7-star rating suggests a practice still establishing its presence in the community.

Endodontics isn’t just about root canals; it covers cracked teeth, traumatic injuries, and even internal bleaching for discolored teeth. While general dentists handle a broad range of issues, endodontists train specifically in diagnosing and treating pain originating from inside the tooth. This specialization can mean more precise care for complex cases—though, as with any medical field, individual experiences vary. The suite number, 400, places the office above street-level businesses, a detail worth noting for first-time visitors.

Finding a specialist often starts with a referral, but direct contact is just as straightforward. Questions about treatment options or insurance can be directed to (650) 340-0225, where staff can confirm whether the practice accepts new patients. Since endodontic work is usually referral-driven, some may not realize they can self-refer for a second opinion. Still, it’s wise to check ahead—especially for procedures like retreatment or apicoectomies, which require a deeper level of expertise.

For those mapping out their visit, the directions show a location convenient to both Caltrain and Highway 92. San Mateo’s mix of medical offices and retail means parking might take a loop or two—but that’s typical for the area. At the very least, the details are all there for the planning.
