Specialist Endodontist
Near Hayward
Hayward patients choose Dr. Jason Kung for specialist-level endodontic care — a straightforward 25-minute drive south on I-880 to our Sunnyvale office, with same-day emergency availability and extended hours 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 Hayward community
Hayward is about a 35-minute drive via 880 and 92, depending on time of day. We see Hayward patients regularly — many referred by general dentists in the Mission–Foothill corridor when a case needs a microscope and CBCT. Hayward patients often choose to drive south specifically because they want a single-specialty endodontic office rather than a general office that does a few root canals between fillings.
