The basics
What a root canal is, and why a crown usually follows
A root canal, known clinically as endodontic treatment, removes infected or inflamed pulp (the nerve and blood supply) from inside a tooth, cleans and disinfects the canals, then fills and seals them. It saves a tooth that would otherwise need to be pulled.
After the pulp is removed, the tooth becomes more brittle and is often left hollow. That is why a dentist almost always recommends a crown afterward, especially on back teeth that take heavy chewing force. The crown caps and protects the tooth so it does not crack. For insurance purposes this matters a great deal: the root canal and the crown are billed and covered on separate lines, often under different benefit categories, each with its own deductible and limits (Delta Dental).
What it costs
What a root canal costs in 2026
Cost rises with the number of canals in the tooth. Front teeth (incisors and canines) usually have a single canal and are simplest. Molars have three or four canals, often curved, and cost the most.
| Tooth type | Canals | Root canal therapy | Plus crown (per tooth) |
|---|---|---|---|
| Front (incisor/canine) | 1 | $700 to $1,100 | $1,500 to $2,500 total |
| Premolar (bicuspid) | 1 to 2 | $800 to $1,300 | $1,600 to $2,800 total |
| Molar | 3 to 4 | $1,000 to $1,600 | $1,700 to $3,200 total |
Sources: Authority Dental, GoodRx, Gentle Dental. A standalone crown typically runs $800 to $2,500, with porcelain or zirconia crowns in mid-tier markets often landing between $1,200 and $1,800 (VIP Dental Care). A molar root canal plus crown can exceed $3,000 out of pocket without coverage (Delta Dental treatment cost). The full job may also include extras billed separately, such as a core build-up ($200 to $450) and sometimes a post ($300 to $600) (Real Dental Costs).
The rules
How PPO dental insurance treats root canals
Major versus basic classification. This is the single most important detail. PPO plans sort procedures into three tiers:
- Preventive (cleanings, exams, x-rays): typically 80 to 100 percent.
- Basic restorative (fillings, simple extractions): typically 70 to 80 percent.
- Major restorative (crowns, bridges, dentures): typically 50 percent.
Root canals can land in either basic or major depending on the policy and sometimes the state. They most often fall under major, but some plans and some states treat endodontics as basic, which means a higher coverage percentage and frequently a shorter waiting period (Animated Teeth, Aflac).
Waiting periods. Major services commonly carry a waiting period of 6 or 12 months, during which the procedure is not covered or is covered at a reduced rate (Amba). If your plan classifies the root canal as basic, the wait is usually shorter. Some carriers waive the waiting period if you had prior dental coverage with no gap.
Annual maximum impact. Most plans cap what they pay per year at $1,000 to $2,000 (MoneyGeek). A molar root canal and crown together can consume most or all of a $1,000 to $1,500 maximum in a single benefit year. A common strategy is to split the root canal and the crown across two plan years so you draw on two annual maximums (Real Dental Costs).
Plan comparison
How CoverCapy PPO plans cover root canals
Most plans classify root canals as a major service. Coverage and timing vary widely, so compare before you enroll.
| Plan | Root canal coverage | Waiting period | Notes |
|---|---|---|---|
| Ameritas PrimeStar Complete | 20% day one, rising to 50% in year two | None | No waiting period |
| Mutual of Omaha Dental Preferred | 20% day one, rising to 50% in year two | None | $5,000 annual maximum |
| Humana Extend 5000 | 50%, rising to 60% in year two | 6 months | Shorter wait than most |
| Guardian Premier 2.0 | 50% | 12 months | Standard major-service terms |
| Delta Dental PPO Premium | 50% | 12 months | Large in-network base |
| Aetna Dental Direct | 50% | 12 months | Wait can be waived with prior coverage |
| UHC Primary Dental | Not covered | Not applicable | Preventive and basic only |
Note: classification can land on basic in some states, which shortens the waiting period.
Maximize benefits
Tips to maximize your coverage
- Confirm the classification in writing. Ask your insurer whether root canals are filed as basic or major on your specific plan and in your state. This determines both your percentage and your wait.
- Request a predetermination. Have the dentist submit the planned codes to your insurer before treatment so you get a written estimate of what the plan will pay.
- Stay in network. PPO plans pay more, and you pay less, when you use an in-network dentist who accepts the plan's negotiated fees.
- Mind the annual maximum. If money is tight, ask whether the root canal and crown can be scheduled across two benefit years.
- Treat early. A small infection caught early may need only a filling rather than a full root canal.
