How much should a root canal cost

The honest answer to how much a root canal should cost is that no agency publishes a price, and any national average you see is a survey. What can be established is the structure of the fee: which tooth, whether a specialist is involved, and whether a crown follows. Those three variables explain most of the variation between quotes.

What the fee is made of

A root canal fee covers the cleaning and sealing of the root canals, the number of which depends on the tooth. A front tooth has one canal, a premolar usually one or two, and a molar two to four. More canals mean more time and a higher fee, which is why a molar costs more than an incisor at the same practice.

The fee is also shaped by who performs the work. A general dentist may perform straightforward cases, while an endodontist handles complex anatomy, retreatments and surgical cases. A referral to a specialist raises the fee and is often the right clinical call.

Finally, most root-treated teeth need a crown to protect them, and the crown is billed separately. A quote for the root canal alone is not the cost of keeping the tooth, and the crown is frequently the larger of the two numbers.

Why no official price exists

Neither the Bureau of Labor Statistics nor Statistics Canada publishes a price series for endodontic treatment. That is worth knowing, because a page that presents a precise national average for a root canal is presenting a survey, and surveys use different samples and definitions from year to year.

The official data that does exist covers consumer prices and health-care indexes. The table below is the Bureau of Labor Statistics average price data, which shows what a genuinely published average looks like and how it is labelled. It is not a dental price.

Treat any published dental average as a starting point for a conversation, not a benchmark to hold a dentist to. The fee for your tooth depends on anatomy that no survey can see.

What changes the quote

The tooth is the biggest single factor. A molar with curved canals and a previous restoration takes longer and carries more risk than a straightforward front tooth. Ask which tooth and how many canals the quote assumes.

A retreatment of a tooth that has already had a root canal is usually more complex and more expensive than a first treatment, because the old filling material must be removed and the canals re-cleaned. A surgical root-end procedure is a different procedure again.

The crown material also moves the price. A metal crown is cheaper than a porcelain or zirconia crown, and the choice depends on the tooth's position and the bite forces it must withstand. Ask for the crown material and its price separately from the root canal.

Insurance and the annual maximum

Dental plans commonly cover a percentage of endodontic treatment after a deductible, subject to an annual maximum. The maximum is the binding constraint: once it is reached, the rest is yours, regardless of medical necessity. Ask your plan for the specific procedure codes and the remaining maximum before treatment.

Some plans require preauthorisation for endodontic treatment or for a crown, and a treatment performed without it may be denied. The practice usually handles the paperwork, but the patient is the one who bears the denial, so confirm that it was submitted.

If the annual maximum is nearly exhausted, ask whether staging the crown into the next calendar year is clinically acceptable. It sometimes is, and it can legitimately reset the benefit without changing the treatment.

Reading and comparing quotes

A comparable quote states the tooth, the number of canals, whether a specialist performs the work, the crown material and the follow-up policy. Without those items, two quotes cannot be compared, and the cheaper one may simply be a smaller scope.

Ask what happens if the tooth cannot be saved during treatment. Occasionally a tooth that looked restorable turns out to be cracked, and the patient has paid for a root canal that cannot be completed. Ask the practice's policy on that scenario before starting.

Ask whether a dental school clinic near you offers the procedure at supervised student rates. It takes longer, but the saving can be substantial, and the quality of supervised endodontic work is generally good.

• Ask for the procedure codes and the fee per code in writing.
• Ask whether the quote includes the build-up and the crown.
• Ask whether the plan requires preauthorisation.
• Ask whether the tooth is restorable before treatment starts.
• Ask about the warranty on the crown.

Financing the treatment

The example below uses the Federal Reserve H.15 bank prime loan rate and a standard amortising schedule. It is arithmetic from a published rate, not a quote, and it gives you a benchmark for any in-house or third-party plan.

Worked example, with the assumption stated: $2,500 borrowed at the Federal Reserve H.15 bank prime loan rate of 6.75% (published 2026-09-16) repaid over 24 months on a standard amortising schedule. That gives a monthly payment of $111.65, total interest of $179.56 and a total repayment of $2,679.56. This is arithmetic from a published rate, not a quote: a real APR includes fees and is set by the lender from your credit, so your figures will differ. If the practice offers an interest-free plan and you clear it in time, that is cheaper. If it does not, compare the two totals over the same term.

Compare the financed total with the cash price, because practices frequently discount payment in full. The discount is the return on paying cash, and it is often larger than the interest on a short loan.
