Specialist Endodontist
Near San Mateo
San Mateo patients who want specialist-level endodontic care choose Dr. Jason Kung — 22 minutes down US-101 in Sunnyvale, with extended evening and weekend hours designed around busy Peninsula schedules.
Why San Mateo Patients Choose Dr. Kung
Our Sunnyvale office is an easy commute from San Mateo via US-101 S. Unlike general dentists who perform root canals as a sideline, Dr. Kung limits his practice exclusively to endodontics — every appointment benefits from his full specialist focus, the Zeiss OPMI operating microscope, and the J. Morita Veraview X800 CBCT in Endo Mode (per the AAE/AAOMR Joint Position Statement on CBCT in Endodontics) when needed.
Microscope-Guided Precision
Every procedure performed under the Zeiss OPMI operating microscope — the standard of care for specialist endodontics.
Same-Day Emergency Care
Tooth pain can't wait. We hold appointments for urgent cases every day, including weekends.
Your Dentist Stays Informed
A detailed clinical report goes to your referring dentist after every visit — you're in good hands, and so is your care team.
Serving the San Mateo community
San Mateo is about a 30-minute drive south on 101 or 280. We see San Mateo patients regularly — downtown and Hillsdale residents, biotech and finance professionals near Bay Meadows, and patients referred by general dentists who don't have a microscope or a J. Morita Veraview X800 CBCT in-office. Many San Mateo patients tell us they tried local generalists first and were referred south specifically for the specialty equipment.
