Santa Clara has both the largest tech employer base in Silicon Valley and one of the most diverse patient communities in California. The right specialist endodontist is the one who delivers modern technology, honest assessment, and care in the language you're most comfortable in. The six criteria below are the same standards the American Association of Endodontists uses to define modern specialist care — apply them to any office you're considering, including ours.
These apply to any office in Santa Clara or anywhere in the Bay Area. Ask the questions before you book.
Two full years of accredited graduate training in endodontics beyond dental school, plus active membership in the American Association of Endodontists. Dr. Kung: UCLA DDS, OHSU MS in Endodontics, active AAE member.
AAE clinical guidelines treat magnification as standard of care for modern endodontics. Many endodontists own a microscope but use it only on select cases. We use a Carl Zeiss surgical microscope on 100% of treatments — required for locating the upper-first-molar MB2 canal (present in ~90% of patients and the single most common cause of late root canal failure).
Cone-beam CT changes the diagnosis or treatment plan in roughly 30% of endodontic cases compared with 2D X-rays alone. Our office has a J. Morita CBCT — no separate imaging appointment, no driving to a radiology center.
About one in eight patients arriving for retreatment leave with a different recommendation — extraction + implant, microsurgery instead of retreatment, or simply monitoring. A specialist willing to tell you when treatment is not the right answer is worth more than one who will treat anything.
Open weekdays until 7 PM and Saturday and Sunday from 9 AM to 3 PM — for major procedures, not only emergencies. One of the only Bay Area endodontic offices that performs scheduled microsurgery on weekends.
Look for review counts above 100, recent reviews in the last six months, and quotes that mention your city or procedure (not just "nice staff"). Dr. Kung: 193+ reviews averaging 4.9★ across Google, Yelp, and Healthgrades, with quotes from patients across Santa Clara County.
Our Sunnyvale office is a straight shot up Lawrence Expressway from most of Santa Clara. We're one of the closest specialist endodontic practices to the Nvidia / Intel / ServiceNow / Applied Materials / Roku tech corridor, and we see many patients referred from general dentists along El Camino Real and Stevens Creek. Santa Clara University students and faculty, families in Rivermark and the Old Quad, and engineers around Levi's Stadium / Tasman make up most of our Santa Clara patient base.
Distance: 4 miles — about 9 min. From most of Santa Clara take Lawrence Expressway south to Hollenbeck and turn right. From the Mission / Tasman corridor, 237 east to Lawrence south. From the Old Quad / SCU area, El Camino Real west to Sunnyvale-Saratoga, then south on Hollenbeck. Typically 7–11 minutes door-to-door outside rush hour.
Who we see from Santa Clara: Nvidia, Intel, ServiceNow, Applied Materials, Roku, AMD, Marvell, Santa Clara University students and faculty, 49ers / Levi's Stadium staff, and families across the Mission, Rivermark, and Old Quad neighborhoods.
Neighborhoods we frequently see patients from: Rivermark & North Santa Clara · Old Quad & Santa Clara University area · Killarney Farms & Mission · Pruneridge & Westwood · Lawrence Station / Birch Park · 49ers Levi's Stadium / Tasman corridor
Use the six criteria: a Specialist Endodontist with a two-year accredited graduate residency, active AAE membership, surgical operating microscope on every case, CBCT 3D imaging on-site, willingness to tell you when treatment isn't the right answer, real evening and weekend hours, and 100+ verified local reviews. Dr. Jason Kung meets all six — UCLA DDS, OHSU MS in Endodontics, AAE member, 100% microscope-guided treatment, J. Morita CBCT, Saturday/Sunday hours, and 193+ reviews at 4.9★.
About 4 miles — roughly 9 minutes from most of Santa Clara via Lawrence Expressway south or El Camino Real west. We're at 1565 Hollenbeck Avenue, Suite 106, Sunnyvale, with free on-site parking. From the Mission / Tasman corridor, 237 east to Lawrence south is the quickest route.
Yes — Santa Clara's tech employer base is one of our largest patient cohorts. We accept and bill all major PPO plans offered through Bay Area tech companies (Delta Dental PPO, MetLife, Cigna, Aetna, Guardian, United Concordia, Anthem Blue Cross). Out-of-network billing is straightforward and you receive your full PPO benefits at our standard fees. Most plans cover 50–80% of specialist endodontic care.
Yes. We're open Monday–Friday until 7 PM and Saturday and Sunday from 9 AM to 3 PM — including for major procedures, not only emergencies. Weekend root canals and weekend apicoectomy (microsurgery) are both available at standard weekday fees. To our knowledge we are one of the only Bay Area endodontic offices that performs scheduled microsurgery on weekends.
Yes. Dr. Kung conducts full clinical visits — history, diagnosis, treatment explanation, and informed consent — directly in Mandarin (普通话). Spanish-speaking staff are available for scheduling and treatment coordination. The website is fully translated into Simplified Chinese (简体中文), Traditional Chinese (繁體中文), Spanish (español), Vietnamese (Tiếng Việt), and four more languages. 我们说中文，hablamos español.
Yes. Every Santa Clara patient receives a clear written estimate before any treatment is scheduled — with the specific ADA procedure codes (D3310 anterior, D3320 premolar, D3330 molar; D3346/D3347/D3348 for retreatment; D3410/D3421/D3425 for apicoectomy) and what your insurance is expected to pay. No surprise billing.
Yes. We hold emergency endodontic slots every day — including weekends — for Santa Clara patients in severe pain, with swelling, or recovering from a dental trauma. Call (669) 234-2354 and we'll do our best to see you the same day. Most root canals are completed in a single visit under our Zeiss surgical microscope.
Call us, ask the questions, decide. Our Sunnyvale office is 4 miles from Santa Clara.
