Six structural reasons — the things that change outcomes, not the things every clinic claims. No "best in the Bay Area," no superlatives, no stock images. Just what Dr. Jason Kung's specialist practice in Sunnyvale actually offers, and why it matters for the tooth you are trying to save.
Dr. Jason Kung's office does only root canal treatment, retreatment, apicoectomy, and the related diagnostic work — no implants, no crowns, no general dentistry. Specialization is the single largest predictor of treatment outcome in published endodontic literature. We do this one thing, all day, every day.
Magnification + coaxial illumination is the difference between finding a calcified MB2 canal and missing it. The microscope is not reserved for difficult cases — it is on the operatory ceiling for every root canal, retreatment, and apicoectomy. (See our microscope-guided endodontics page for the evidence base.)
Small-volume 80 µm voxel, 40 × 40 mm field of view — the high-resolution protocol the AAE/AAOMR Joint Position Statement on the Use of CBCT in Endodontics recommends. Used to detect missed canals, vertical root fractures, resorption, sinus-floor involvement, and second-opinion cases where a 2D radiograph cannot answer the question.
We are one of the only endodontic offices in the Bay Area open Saturday and Sunday (8 AM – 3 PM). Same-day emergency slots every day. Urgent referrals from general dentists are seen within 24–48 hours.
Dr. Kung is fluent in both Mandarin and English. Patient education, consent, and post-treatment instructions are delivered in the language the patient speaks at home — which materially affects post-op compliance and outcomes.
Every treatment plan uses the AAE Treatment Options for the Compromised Tooth (2014) framework: favorable / questionable / unfavorable. If a tooth should not be saved, we say so. If a less invasive option exists, we offer it. The booking incentive does not bend the diagnosis.
