A Korean Speaker's Guide to Seeing a U.S. Endodontist

If you grew up in Korea and are now living in Silicon Valley, navigating a U.S. dental office for a specialized procedure like a root canal can feel daunting. Even patients who speak English well often find themselves confused by dental terminology. This guide is written to help Korean-speaking patients understand every step of the process—from scheduling through recovery.

What Is an Endodontist?

A general dentist (치과의사, chi-kwa-eui-sa) handles most routine dental care. An endodontist (치과신경과 전문의, chi-kwa-shin-gyeong-gwa jeon-mun-eui) is a dental specialist who, after completing dental school, goes on to an additional 2–3 year residency focused entirely on the inner structures of the tooth—the pulp, nerves, and root canals. According to the American Association of Endodontists, endodontists perform an average of 25 root canal procedures per week, compared to two per week for a general dentist.

In the U.S., your general dentist will often write a referral (의뢰서, eui-roe-seo) to an endodontist when your tooth needs more specialized care. Dr. Jason Kung, DDS, MS, completed his endodontic specialty training at UCLA and OHSU and sees patients throughout the South Bay and Silicon Valley at Silicon Valley Endodontics & Microsurgery in Sunnyvale, CA.

Key Dental Terms You'll Hear (English / Korean)

One of the biggest challenges for Korean-speaking patients is the vocabulary. U.S. dental staff use technical English terms quickly and may not realize you're unfamiliar with them. Before your appointment, review our Korean-English Root Canal Glossary, which lists more than 40 of the most common terms side by side.

A few of the most important ones:

• Root canal (신경치료 / 근관치료) — the procedure that removes infected pulp from inside the tooth
• Pulp (치수) — the soft tissue inside the tooth containing nerves and blood vessels
• Crown (크라운 / 치관 보철) — a cap placed over the tooth after root canal treatment
• X-ray / CBCT (방사선 촬영 / 3D CT 촬영) — imaging used to diagnose and plan treatment
• Local anesthetic (국소마취) — numbing injection given before the procedure

Bring a printed or phone copy of the glossary to your appointment. It is perfectly acceptable—and appreciated by most dental offices—for patients to reference a vocabulary list.

What to Expect During a Root Canal

A root canal procedure in the U.S. typically takes one to two visits. Here is what happens at each stage:

1. Consultation and imaging — The endodontist reviews your X-rays or CBCT scan, examines the tooth, and confirms a diagnosis. This is the time to ask all your questions.
2. Anesthesia — A local anesthetic is injected around the tooth. You will feel pressure but should not feel pain. If you do feel pain, tell the dentist immediately—more anesthetic can always be given.
3. Cleaning the canals — The endodontist opens the tooth, removes the infected pulp, and cleans the root canals with small instruments and an antimicrobial rinse.
4. Sealing — The cleaned canals are filled with a rubber-like material called gutta-percha and sealed. A temporary or permanent filling closes the access opening.
5. Crown — In most cases, your referring dentist will place a crown (cap) over the treated tooth within a few weeks to protect it long-term.

Cost and Insurance in the U.S.

U.S. dental insurance works very differently from health insurance—and very differently from Korea's National Health Insurance. Here is a brief overview:

• Dental PPO plans are the most common. They cover a percentage of specialist fees (often 50–80%) even when the specialist is out-of-network.
• Annual maximum — Most PPO plans have a yearly cap (usually $1,000–$2,000) on what they will pay. Once you hit the maximum, you pay 100% out of pocket for the remainder of the year.
• Deductible (공제액) — An amount you pay before insurance kicks in, typically $50–$100 per year.
• EOB (Explanation of Benefits) — A document your insurance sends after a claim, showing what was covered and what you owe. It is not a bill.

Silicon Valley Endodontics is an out-of-network provider for all PPO dental plans. That means we are not contracted with any specific insurance company—but your PPO plan likely still covers a meaningful portion of your fees. We provide a detailed pre-treatment cost estimate and can submit your claim on your behalf. For patients who want to spread payments over time, we accept CareCredit financing. Learn more on our insurance & billing page.

If you do not have dental insurance, root canal fees at a specialist in the South Bay typically range from $1,400 to $2,200 for a single tooth depending on complexity, before the cost of a crown. Our front desk is happy to provide an itemized fee estimate over the phone before you book.

Communicating at Your Appointment

Here are some practical tips for navigating an English-language appointment:

• Bring someone with you — A bilingual friend or family member can help translate during the consultation. Tell the front desk when booking so they can schedule a longer appointment.
• Write down your symptoms beforehand — Note where the pain is, how long it has been there, what makes it better or worse, and any medications you take. Hand the note to your dentist at the start of the visit.
• Ask for everything in writing — Diagnosis, treatment plan, and cost estimate. Most offices are happy to email or print a summary.
• It's okay to ask the dentist to slow down — Say "Could you please explain that again more slowly?" — most dental professionals are accustomed to patients needing clarification.
