Specialist Endodontist
Near San Francisco
San Francisco patients who need specialist endodontic care make the 48-minute drive down US-101 to Dr. Jason Kung's Sunnyvale office — a purpose-built endodontic suite with operating-microscope precision, the J. Morita Veraview X800 CBCT in Endo Mode (the small-volume, high-resolution protocol the AAE/AAOMR position statement recommends for endodontic diagnosis), and same-day emergency appointments.

Why San Francisco Patients Choose Dr. Kung
From San Francisco's Mission District, SoMa, or the Financial District, US-101 S or I-280 S lead directly to our Hollenbeck Avenue office in Sunnyvale. Dr. Kung's graduate residency, MS in Endodontics, and Zeiss OPMI microscopy deliver a standard of specialist care that makes the drive south worthwhile — especially for complex retreatments and apicoectomies.
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 Francisco community
San Francisco is about a 50-minute drive south on 280 or 101. SF patients drive down for a few specific reasons: they want a Zeiss surgical microscope and J. Morita Veraview X800 CBCT not available at every SF general office, they have weekend availability we offer (we're open Saturday and Sunday — full details on the dedicated emergency-root-canal-san-francisco page), or their SF general dentist has referred them to us specifically for a case requiring microsurgery or retreatment.
