A root canal can save a damaged or infected tooth, but it is a more involved procedure than a routine filling, and the cost reflects that. If you need one, the key question is how much your dental plan will pay. Here is how dental insurance typically handles root canals in 2026 and how to lower what comes out of your pocket.
How plans cover root canals
Most dental plans cover root canals, often classifying them as a basic or major service depending on the plan. That determines the percentage the plan pays after your deductible. Coverage is usually higher in-network, so using a participating dentist or endodontist reduces your share.
What affects the cost
The cost of a root canal depends on the tooth involved, since molars have more canals and are more complex than front teeth. More complex cases take longer and cost more, which can affect both the total bill and how the plan applies coverage.
Don’t forget the crown
A tooth that has had a root canal often needs a crown to protect it afterward. The crown is usually billed as a separate major service, so factor it into your planning. Together, the root canal and crown can approach or exceed some plans’ annual maximum.
Annual maximum and waiting periods
Because root canals and crowns are significant expenses, your annual maximum and any waiting period for major work matter. If treatment is not urgent and your plan has a waiting period, timing can affect how much the plan pays.
Reducing your cost
Use an in-network provider, ask for a pre-treatment estimate, and check how the root canal and crown will be billed across the calendar year. If the combined cost exceeds your annual maximum, spreading treatment across two plan years may help.
How to plan for a root canal
Confirm how your plan classifies the procedure, use an in-network dentist or endodontist, get a pre-treatment estimate, and budget for a crown if one is needed.

Final thoughts
Dental insurance generally covers root canals, but your share depends on the plan’s rules, the tooth involved, and whether a crown follows. Get a pre-treatment estimate, stay in-network, and plan around your annual maximum to keep the cost of saving your tooth manageable in 2026.
