Cupertino has more endodontists within a short drive than almost any city in the country. Choosing well matters — a root canal performed without a microscope or CBCT may need to be redone in five to ten years. 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 Cupertino 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 sits one freeway exit east of Cupertino. Many of our Cupertino patients are referred by general dentists in the Stevens Creek dental corridor when a case needs a CBCT scan, surgical operating microscope, and a dedicated endodontic specialist. We also see a steady stream of Apple, Seagate, and De Anza-area professionals who need an appointment that fits between meetings — early morning, lunchtime, after work, or on a weekend.
Distance: 3.5 miles — about 8 min. From Cupertino take Wolfe Road north to 280 east, exit Lawrence Expressway south, then a quick right on Hollenbeck. Or stay on Stevens Creek east to Lawrence Expressway. Both routes are 8–12 minutes door-to-door outside rush hour.
Who we see from Cupertino: Apple Park employees, Seagate, De Anza College students and faculty, Homestead High families, and patients across the Stevens Creek dental corridor and Wolfe Road area.
Neighborhoods we frequently see patients from: Rancho Rinconada & Garden Gate · Monta Vista & Stevens Creek corridor · Inspiration Heights & Linda Vista · Seven Springs & South Cupertino · Fairgrove & Oak Valley · Apple Park / Wolfe Road area
Cupertino has several specialist endodontic offices within a few miles, so the choice usually comes down to fit: a Specialist Endodontist with a CODA-accredited postgraduate residency, active AAE membership, surgical operating microscope used from the diagnostic exam onward (not just during treatment), on-site CBCT 3D imaging following the AAE/AAOMR 2025 Joint Position Statement, real evening and weekend availability, and 100+ verified local reviews. Dr. Jason Kung meets all of those — UCLA DDS, OHSU MS in Endodontics (CODA-accredited residency), AAE member, 100% microscope-guided from exam through obturation, J. Morita Veraview X800 CBCT, Mon–Fri until 7 PM and Sat/Sun 9–3, and 193+ reviews at 4.9★.
Dr. Kung is a Specialist Endodontist — California-licensed to practice and advertise as such after completing a two-year CODA-accredited postgraduate residency in Endodontics at OHSU. He is not currently a Diplomate of the American Board of Endodontics (ABE board certification is a voluntary exam taken after residency). We mention this proactively because some Cupertino-area specialists are board-certified Diplomates, and we believe patients deserve a straight answer rather than vague "specialist" language. CODA-accredited residency is the credential the California Dental Board requires to practice as a specialist; ABE Diplomate status is an additional voluntary credential held by a minority of practicing endodontists. If ABE Diplomate status is the single most important factor for you, ask any office you call — including ours — directly.
Yes — we hold late-afternoon and early-evening slots Monday through Friday until 7 PM, which is one to two hours past when most Cupertino-area endodontic offices close. Leave Apple Park at 5:30, take Wolfe Road north to 280 east, exit Lawrence Expressway, and you're in our chair by 6 — most root canals finish in 60–90 minutes, so you're home before dinner. See the after-work root canal page for the full evening workflow.
About 3.5 miles — roughly 8 minutes from central Cupertino via Stevens Creek Boulevard or Homestead Road. We're at 1565 Hollenbeck Avenue, Suite 106, Sunnyvale, with free on-site parking and easy access from De Anza Boulevard, Wolfe Road, and the 280 freeway.
Yes. We hold emergency endodontic slots every day — including Saturdays and Sundays — for Cupertino patients in severe pain, with swelling, or recovering from a dental trauma. Call (669) 234-2354 in the morning and we'll do our best to fit you in that day. Most root canals are completed in a single visit under our Zeiss surgical microscope.
Yes. We're open Monday–Friday until 7 PM and Saturday and Sunday from 9 AM to 3 PM — designed for Apple, Seagate, and other Cupertino tech professionals who can't take time off mid-week. Weekend root canals and weekend microsurgery (apicoectomy) are both available at standard weekday fees.
Yes. Dr. Kung conducts patient consultations, treatment explanations, and informed-consent conversations directly in Mandarin (普通话), and Mandarin-speaking staff are available for scheduling and treatment coordination. Our website is fully translated into Simplified Chinese (简体中文) and Traditional Chinese (繁體中文). 我们说中文，欢迎库比蒂诺华人社区的朋友们。
We accept and bill PPO plans from all major carriers — Delta Dental PPO, MetLife, Cigna, Aetna, Guardian, United Concordia, and Anthem Blue Cross. We are out-of-network for most PPOs, which means we submit claims on your behalf and you receive your full PPO benefits at our standard fees. Most plans pay 50–80% of specialist endodontic fees. You'll get a clear written estimate before any treatment is scheduled — no surprises.
Absolutely. We send a detailed clinical report — including the CBCT scan, intraoral photos, and the final radiograph — to your referring Cupertino dentist within 24 hours of every visit, so your care team stays coordinated and your crown can be placed on schedule.
Call us, ask the questions, decide. Our Sunnyvale office is 3.5 miles from Cupertino.
