Specialist Endodontist
Near Boulder Creek
Boulder Creek patients drive about 55 minutes over Highway 17 and CA-9 to our Sunnyvale specialist endodontic office — worth the trip for microscope-guided root canal treatment, retreatments, and complex cases that general dentists prefer to refer to a specialist.
Why Boulder Creek Patients Choose Dr. Kung
From the redwood-canopied streets of Boulder Creek, our office is a scenic drive over the Santa Cruz Mountains via CA-9 to Highway 17 N, then 85 N. Dr. Kung's practice is dedicated entirely to endodontics, with Zeiss OPMI microscope-guided treatment and 3D CBCT imaging on every complex case.
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 Boulder Creek community
Boulder Creek and the broader San Lorenzo Valley have limited specialist endodontic options — most general dentists refer over the hill. We see Boulder Creek patients primarily for retreatment of failing root canals, apicoectomy, and complex diagnostic cases where the CBCT changes the treatment plan. We make every effort to consolidate the work into a single appointment so you don't have to make the drive twice.
