A root canal costs $700 to $1,800 for the procedure itself, depending mostly on which tooth needs it — and most teeth then need a crown at $800–$2,500 on top. The all-in cost of saving a back tooth therefore usually lands between $1,800 and $4,300.
That two-part structure — the root canal plus the crown — is the single most important thing to understand before you get a quote, because a “$1,000 root canal” is rarely the whole story. Here’s the full 2026 breakdown by tooth, what insurance actually pays, and how to bring the number down.
Root canal cost by tooth
Back teeth cost more because they have more canals to find, clean, and seal:
| Tooth | Canals | Root canal alone | + crown (typical) |
|---|---|---|---|
| Front tooth (incisor/canine) | 1 | $700 – $1,100 | often filling only, or +$800–$2,000 |
| Premolar (bicuspid) | 1 – 2 | $800 – $1,400 | +$800 – $2,500 |
| Molar (back tooth) | 3 – 4 | $1,000 – $1,800 | +$900 – $2,500 |
| Molar retreatment | 3 – 4 | $1,000 – $2,000 | +$900 – $2,500 |
Who does it also matters: a general dentist typically charges less than an endodontist (root-canal specialist), but specialists are worth it for molars, retreatments, and complex anatomy — they do these all day and have better tools for it.
The crown is not optional (on most teeth)
A root canal removes the infected nerve and pulp, which leaves the tooth hollow and more brittle — molars especially, because they absorb the most chewing force. A crown caps and protects it. The math people get wrong:
Skipping the crown to save money is the leading cause of a root-canaled tooth cracking months later — and a cracked root-canaled tooth usually can’t be saved, sending you to a $3,000+ implant. The $1,200 crown protects the $1,200 root canal.
Front teeth, which take less force, sometimes need only a filling to seal the access hole. But for any premolar or molar, budget for the crown from the start.
The full quote: line items to expect
| Item | Typical cost | When |
|---|---|---|
| Exam + X-rays | $50 – $250 | Always (often credited) |
| Root canal | $700 – $1,800 | The procedure |
| Post & core buildup | $250 – $650 | When little tooth structure remains |
| Crown | $800 – $2,500 | Almost always on back teeth |
| Sedation (optional) | $250 – $800 | Your choice |
| Retreatment (if a prior RCT failed) | +$200 – $500 over first-time | Redo cases |
Root canal cost with insurance
Most dental plans cover root canals at 50–80% after the deductible, within the annual maximum ($1,000–$2,000). The catch is that a molar root canal + crown can total $2,500–$4,300, so a single tooth often uses up your entire yearly benefit — and the crown may spill into a second calendar year.
Two moves that help:
- Ask for a pre-treatment estimate so your exact out-of-pocket is confirmed in writing before treatment.
- Time the crown across plan years if clinically safe — root canal in December, crown in January — to use two annual maximums. Confirm with your dentist that waiting won’t risk the tooth.
6 debt-free ways to pay less
None of these involve loans or financing — just lower actual prices:
- Dental school endodontics clinics perform root canals at 40–60% off under faculty supervision — a molar root canal for $400–$800 instead of $1,400. Search “[your state] dental school endodontics clinic.”
- Community health centers (FQHCs) charge income-based sliding-scale fees and handle root canals — HRSA locator in sources.
- General dentist vs. endodontist. For a straightforward front tooth or premolar, a general dentist often costs less. Save the specialist for molars and retreatments where the higher success rate earns its price.
- Ask for the cash-pay discount — 5–10% off for payment in full is common.
- Use HSA/FSA money — a root canal is a qualified medical expense, so pre-tax dollars cut the real cost by your tax rate.
- Don’t wait. An infected tooth only gets more expensive: what’s a $1,200 root canal today becomes an extraction-plus-implant tomorrow if the tooth becomes unsalvageable. If pain or swelling is present, a community health center or dental school will see urgent cases quickly.
Root canal vs. extraction: the real comparison
| Root canal (+ crown) | Extraction + replacement | |
|---|---|---|
| Upfront | $1,800 – $4,300 | $150 – $700 (pull) then $2,000 – $4,500 (implant/bridge) |
| Keeps your natural tooth | Yes | No |
| Total within ~3 years | $1,800 – $4,300 | $2,150 – $5,200 |
| Neighboring teeth | Untouched | May shift if space left empty |
Pulling the tooth is cheaper today and more expensive soon, because an empty socket needs an implant or bridge to keep the other teeth from drifting. Unless the tooth is truly unsalvageable, saving it with a root canal is the cheaper long-term path — which is exactly why dentists recommend it.
What actually happens (it’s not the horror story)
A modern root canal is done under local anesthetic and feels much like a filling — the severe pain people associate with it is almost always the infection beforehand, which the procedure relieves. In one or two visits, the dentist numbs the tooth, removes the infected pulp, cleans and shapes the canals, fills them, and seals the tooth (with a temporary filling if a crown is coming). Mild tenderness for a few days is normal. Then the crown appointment protects your investment — see our crown cost guide for that half of the bill and how to save on it.
