Specialist Endodontist
Near Sunnyvale
Silicon Valley Endodontics & Microsurgery is located right here in Sunnyvale on Hollenbeck Avenue, Suite 106. Dr. Jason Kung is the South Bay's specialist endodontist for precision root canal treatment, endodontic microsurgery, and same-day emergency care — all performed under the Zeiss OPMI operating microscope.
Why Sunnyvale Patients Choose Dr. Kung
Sunnyvale patients don't have to travel for specialist endodontic care — we're right in your community. Dr. Kung trained at UCLA (DDS) and OHSU (MS in Endodontics) and limits his practice entirely to endodontics. Whether you need a first-time root canal, a retreatment, or an apicoectomy, you're getting a dedicated specialist, not a general dentist performing the occasional root canal.
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 Sunnyvale community
Our office is on Hollenbeck Avenue in Sunnyvale's Cherryhill neighborhood, a few minutes from Murphy Avenue and Sunnyvale Caltrain. We see Sunnyvale neighbors every day — patients walking over from Lakewood Village, parents picking kids up after school in Cherry Chase, and tech workers stopping by between meetings at the LinkedIn, Apple, and Google campuses on either side of Mathilda. Because the practice limits itself to endodontics, your general dentist and Dr. Kung can coordinate care quickly without you crossing town.
