Specialist Endodontist
Near San José
San Jose patients choose Dr. Jason Kung for specialist endodontic care they can trust — just 15 minutes up the Lawrence Expressway or I-280. Our clinic offers multilingual support (English, Spanish, Mandarin, Cantonese, Vietnamese, and Farsi) to serve San Jose's diverse communities.
Why San José Patients Choose Dr. Kung
San Jose is the largest city in the Bay Area, and many residents travel to Sunnyvale for specialty dental care. Dr. Kung's practice is conveniently accessible from North San Jose, Willow Glen, Berryessa, and the East Side via multiple expressways. We speak your language — our team communicates in English, Spanish, Traditional and Simplified Chinese, Vietnamese, and Farsi — making specialist care more accessible to San Jose's multilingual community.
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 José community
San José is large, so the drive depends on neighborhood — about 15 minutes from west San José and Santana Row, 20–25 from Almaden, Berryessa, or Evergreen. We see San José patients across every district, and we work routinely with San José general dentists who refer cases that need a microscope, J. Morita Veraview X800 CBCT imaging (Endo Mode), or microsurgery. Because we limit our practice entirely to endodontics, your general dentist sends the case to us, we treat the tooth, and you go back to them for the crown — no fragmented care.

- Willow Glen & Lincoln Avenue
