Saratoga patients tend to do their research before they pick up the phone — and rightly so. The criteria below are the same ones the American Association of Endodontists uses to define modern specialist care, applied honestly to any office in or near Saratoga, including ours. 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 Saratoga 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 12 minutes north of Saratoga along Saratoga-Sunnyvale Road or Highway 85. Many of our Saratoga patients are referred by general dentists in downtown Saratoga, Los Gatos, and Monte Sereno for retreatment of older root canals, evaluation of cracked teeth that need CBCT imaging, or microsurgery on persistent apical lesions. Families in Saratoga Village, Quito, and the hills above Pierce Road make up most of our Saratoga patient base, alongside professionals working from home offices across west San Jose / Saratoga.
Distance: 7 miles — about 12 min. From Saratoga take Saratoga-Sunnyvale Road north for about 6 miles, then turn right onto Fremont Avenue and continue to Hollenbeck Avenue. From west Saratoga, Highway 85 north to the Fremont Avenue exit is typically the fastest route at 12–14 minutes outside rush hour.
Who we see from Saratoga: Saratoga-Los Gatos high school families, retired tech executives, professionals in private equity, biotech, and law working hybrid from home, and patients referred by general dentists in downtown Saratoga, Los Gatos, and Monte Sereno.
Neighborhoods we frequently see patients from: Saratoga Village & Big Basin Way · Quito & Glen Una · Pierce Road & the hills above Saratoga · Argonaut & Brookview · Congress Springs & Sunland Park · Monte Sereno (adjacent) · Saratoga Country Club / Mountain Winery area
Use the six criteria: a Specialist Endodontist with a two-year accredited graduate residency, active AAE membership, a surgical operating microscope used 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 7 miles — roughly 12–15 minutes from downtown Saratoga via Saratoga-Sunnyvale Road north, or 12 minutes from west Saratoga via Highway 85 north to the Fremont Avenue exit. We're at 1565 Hollenbeck Avenue, Suite 106, Sunnyvale, with free on-site parking. From the Saratoga Village / Big Basin Way area, the most reliable route is Saratoga-Sunnyvale Road straight north for 6 miles, then right on Fremont Avenue.
Yes — second opinions and retreatment evaluations are a large portion of our Saratoga referrals. Many Saratoga patients had a successful root canal 10–20 years ago and the symptoms recurring now are usually from a missed canal (often the upper-first-molar MB2), a hairline crack, or a leaking restoration above the root canal. CBCT 3D imaging plus a 25× microscope exam usually pinpoints the cause in a single visit, and modern retreatment succeeds in 78–87% of cases.
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 — useful for Saratoga professionals who can't take weekday time off.
Yes. Dr. Kung conducts full clinical visits — history, diagnosis, treatment explanation, and informed consent — directly in Mandarin (普通话). Many Saratoga families prefer detailed clinical conversations in Chinese rather than working through an interpreter. The website is fully translated into Simplified Chinese (简体中文) and Traditional Chinese (繁體中文). 我们说中文。
Yes. We hold emergency endodontic slots every day — including weekends — for Saratoga 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.
Yes — that's the standard handoff. We complete the root canal or microsurgery and send a referral note plus all imaging back to your general dentist the same day. Your Saratoga or Los Gatos dentist places the crown 4–6 weeks later (or same-day if they offer CEREC). We work with most general dentists across Saratoga, Los Gatos, Monte Sereno, and west San Jose.
Call us, ask the questions, decide. Our Sunnyvale office is 7 miles from Saratoga.
