Specialist Endodontist
Near Dublin
Dublin patients choose Dr. Jason Kung for specialist endodontic care — just 32 minutes south on I-680 to our Sunnyvale office, where every procedure is performed under an operating microscope with same-day emergency availability.
Why Dublin Patients Choose Dr. Kung
From Dublin's BART station or Hacienda Business Park, I-680 S connects directly to our Hollenbeck Avenue office. Dr. Kung's graduate residency and MS in Endodontics, combined with Zeiss OPMI microscopy and CBCT imaging, deliver a standard of care that sets him apart from general dentists performing root canals.
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.
