How to Choose the Right Endodontist in the South Bay
Choosing an endodontist in Silicon Valley? Learn what credentials, technology, and questions matter most before your root canal or microsurgery.
Getting a referral to an endodontist can feel overwhelming, especially when you're already dealing with tooth pain or a nerve problem. You may have a few names in hand, or you may be searching online at 11 p.m. with a throbbing jaw. Either way, knowing what to look for can help you make a confident, informed choice — one you won't regret once you're in the chair.
Start With Actual Specialty Training
Endodontics is one of the nine dental specialties recognized by the American Dental Association. To call yourself a specialist endodontist, a dentist must complete a two- to three-year postgraduate residency program at an accredited dental school — on top of dental school itself. This training goes far beyond what a general dentist receives, covering complex root canal anatomy, microsurgery, dental trauma, and root-end procedures.
When evaluating a provider, confirm that they completed a formal endodontic residency. It's worth asking where they trained. Dr. Jason Kung, for example, completed his specialty training at both UCLA and OHSU — two of the most rigorous programs in the country. That background matters when your case isn't straightforward.
You can also verify a dentist's specialty status through the American Dental Association or the California Dental Association's license lookup tool.
Look for Advanced Diagnostic Technology
The best endodontic outcomes start with accurate diagnosis. A specialist who relies on two-dimensional X-rays alone is working with limited information — especially for complex cases involving multiple canals, hidden fractures, or previous failed treatment.
Modern endodontic practices use cone-beam computed tomography (CBCT) — a low-dose 3D imaging system that gives a far more complete picture of root anatomy, bone loss, and surrounding structures. This technology helps catch problems that flat X-rays simply miss and allows for a more precise treatment plan before anything begins.
Ask prospective offices whether they have CBCT imaging on-site. When it's in-house, your consultation is faster and your diagnosis is more complete from day one.
Ask About the Surgical Microscope
This one detail separates a true endodontic specialist from a general dentist offering root canals on the side. A dental operating microscope — like the Zeiss OPMI used at Silicon Valley Endodontics — provides magnification up to 25 times and coaxial lighting that illuminates the inside of a root canal with extraordinary clarity.
With a microscope, a specialist can locate calcified canals, identify microcracks, and perform apicoectomy (microsurgery) with the kind of precision that simply isn't possible with the naked eye. If an office doesn't use a surgical microscope routinely, that's a meaningful limitation — especially for difficult or previously treated teeth.
Consider the Scope of Services
Endodontic needs vary. Some patients need a first-time root canal on a straightforward tooth. Others need a retreatment because a previous root canal didn't heal as expected. Some cases involve cracked teeth, traumatic injuries, or even regenerative procedures for young patients with incompletely formed roots.
A specialist who handles the full spectrum of endodontic care is better positioned to accurately diagnose your problem and recommend the right treatment — not just the treatment they happen to offer. When evaluating an office, look at the full list of services they provide.
Read Reviews — But Read Them Critically
Online reviews are a useful signal, but they're not the whole picture. Look for patterns rather than outliers. A practice with dozens of reviews consistently praising the doctor's calm demeanor, thoroughness, and clear explanations is telling you something real. A handful of five-star reviews with generic language may not be.
Pay attention to reviews that specifically mention:
- Whether the doctor explained the diagnosis clearly
- How the staff handled insurance or billing questions
- How pain was managed during and after the procedure
- Whether anxious patients felt reassured
These details reflect the day-to-day experience at a practice — not just the clinical outcome.
Understand the Financial Picture Before You Commit
Specialty dental care involves real costs, and surprises are stressful. Before scheduling, ask the office to explain exactly how insurance works with their practice. Some endodontists are in-network with your PPO; others are not.
Silicon Valley Endodontics & Microsurgery is out-of-network with all PPO plans. That means the office will provide a detailed fee estimate upfront, and most PPO plans still reimburse a portion of the cost — it just requires you to submit a claim or have the office do it on your behalf. The office does not accept medical insurance and does not offer in-house payment plans, but CareCredit financing is available for patients who want to spread the cost over time.
Transparency here is a good sign in any practice. If an office is vague about costs or insurance until after treatment, that's worth noting.
Single-Doctor Practices vs. Group Practices
In the South Bay, you'll find both large multi-doctor specialty groups and smaller single-doctor practices. There's no universal right answer, but it's worth knowing what you're choosing. In a single-doctor practice, you see the same specialist every time — your consultation, your procedure, and any follow-up are all with the same person who knows your case.
At Silicon Valley Endodontics & Microsurgery, Dr. Kung personally handles every case from start to finish. There's no hand-off to an associate or a rotating schedule. For complex or anxious cases especially, that continuity can make a meaningful difference in your comfort and outcomes.
Trust Your First Impression at the Consultation
A consultation isn't just a diagnostic appointment — it's also a chance to evaluate how a specialist communicates. Did they take time to look at your imaging and explain what they found? Did they answer your questions directly, without rushing? Did the office feel organized and calm?
Endodontic treatment works best when you feel informed and supported. A specialist who listens well and explains your options clearly is one worth trusting with your tooth.
