Specialist Endodontist
Near Pleasanton
Pleasanton patients seeking the highest standard of endodontic care travel 35 minutes on I-680 S to Dr. Jason Kung's Sunnyvale office — equipped with an operating microscope, CBCT 3D imaging, and same-day emergency scheduling.

Why Pleasanton Patients Choose Dr. Kung
From Pleasanton's downtown or Hacienda Business Park, I-680 S is a direct route to our Hollenbeck Avenue office. Dr. Kung's two-year specialist residency and MS in Endodontics bring a depth of training that general dentists lack — particularly valuable for retreatments, failed root canals, 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.
