Most patients want to know what a root canal will actually cost before they sit in the chair. Here are the real out-of-pocket ranges for Cupertino patients at our Sunnyvale office — by tooth type, by CDT code, with and without PPO insurance.
The ranges below reflect typical patient out-of-pocket at our office after PPO benefits, and our self-pay fee. See what each CDT code means →
| Procedure | With PPO | Without insurance |
|---|---|---|
Front tooth (anterior) — D3310 Single canal, simplest RCT | $200–$650 | $1,150–$1,500 |
Premolar — D3320 One or two canals | $250–$750 | $1,350–$1,700 |
Molar — D3330 Three to four canals; most common | $400–$1,200 | $1,700–$2,200 |
Retreatment (molar) — D3348 Redoing a previous root canal | $500–$1,400 | $1,950–$2,500 |
Apicoectomy (microsurgery) — D3425 Root-end surgery for failed RCT | $500–$1,500 | $2,100–$2,800 |
What's included in our fee
All root canal fees include: clinical examination, all diagnostic X-rays, CBCT scan if clinically indicated, the full root canal procedure under microscope, working-length apex locator, rubber dam isolation, temporary filling, and post-op call within 48 hours. Not included: the final crown or filling (your general dentist places that under separate codes — D2740/D2950/D2954).Most Cupertino-area tech employers offer Delta Dental, Cigna, MetLife, Aetna, or Guardian PPO dental plans. We're out-of-network with all PPOs but file claims on your behalf as a courtesy:
Easiest path
Email a photo of the front and back of your insurance card to siliconvalleyendo@gmail.com — we'll verify benefits and email you back a personalized estimate before your visit.Out-of-pocket cost depends on the tooth, your insurance plan, and whether retreatment or microsurgery is needed. With a major Bay Area PPO, patient share at our office typically runs $200–$1,400 for first-time root canal treatment. We file with all major PPOs as a courtesy and give you a written estimate before any treatment.
Most Cupertino tech employers (Apple, Seagate, Trend Micro, etc.) offer Delta Dental, Cigna, MetLife, or Aetna PPOs. We're out-of-network with all PPOs but file claims on your behalf and are typically reimbursed at the out-of-network rate, which is usually only modestly less than in-network. Email your insurance card to siliconvalleyendo@gmail.com and we'll verify benefits before your visit.
A specialist endodontist (us) and a general dentist may bill the same CDT code (D3310/D3320/D3330) at similar fees in Cupertino. The difference is what's included: every visit at our office uses surgical microscope + CBCT when needed + rubber dam isolation. For molars and retreatments — where missed canals are common — that workflow is what drives long-term success rates.
Yes — our office serves all of the South Bay from a single Sunnyvale location, and we charge the same fees regardless of which city you live in. Cupertino patients typically drive 10–15 minutes; we validate parking and offer Saturday hours.
We offer CareCredit financing (often 0% APR for 6–12 months), accept HSA/FSA, and can sometimes split treatment across two benefit years to maximize annual insurance maximums. Call (669) 234-2354 — we'd rather help you afford treatment than have you lose a tooth.
Molars typically have 3–4 canals (sometimes more, including the MB2 canal in upper molars), take roughly twice as long to treat, and require advanced anatomy mapping with microscope and CBCT. The CDT code (D3330) and insurance fee schedules reflect that complexity.
Pricing ranges reflect typical patient out-of-pocket at our Sunnyvale office. Your specific cost depends on your plan, deductible, annual maximum, and clinical factors. Final fees are always confirmed in writing before treatment.
