How Much Does a Root Canal Cost in Ontario?

Root canal cost in Ontario depends mainly on which tooth is treated, because molars have more canals than front teeth, and on whether the tooth needs a crown afterward. Each dentist sets their own fees, and most private dental plans cover part of the treatment. The Canadian Dental Care Plan also covers standard root canals for eligible patients.

If you have been told you need a root canal, the price is usually only part of the picture. The full cost of saving a tooth often includes an exam, X-rays, the root canal itself and a permanent filling or crown. This guide from Tomken Dental explains how root canal fees in Ontario are set, what changes the price, what insurance and the CDCP cover, how root canal costs compare with extraction and replacement, and what to expect at our office in Mississauga.

How Are Root Canal Fees in Ontario Set?

Root canal fees in Ontario are set by each dental office. Many dentists and insurers use the Ontario Dental Association’s annual Suggested Fee Guide as a reference, but dentists are not required to follow it, so fees can sit above or below the guide. Specialists, such as endodontists, have additional factors that influence their fees.

The Ontario Dental Association explains that office location, overhead and the time a procedure takes all influence fees. Many insurance plans also base their reimbursement on the fee guide’s codes and amounts, which is why your plan may pay a set amount even if your dentist’s fee is a little different.

Because fees vary, the most reliable number is a written estimate for your specific tooth. Ask for the procedure codes, which make it easier to check coverage with your insurer. If you are comparing offices, make sure each estimate covers the same steps, such as X-rays, the number of visits and the final restoration. A lower root canal fee with a separate charge for the build-up and crown may cost the same, or more, in total.

What Affects Root Canal Cost in Ontario?

The biggest factors in root canal cost in Ontario are the tooth type, the number and shape of its canals, how infected or complex the case is, whether it is a first treatment or a retreatment, and who performs it. Additional visits, imaging and the final restoration add to the total.

Front teeth, premolars and molars

Front teeth (incisors and canines) usually have one canal and are the most straightforward. Premolars often have one or two. Molars, the large back teeth, usually have three or four canals, sometimes with complex anatomy, so they take longer and cost more.

Retreatment and specialist care

If a tooth that had a root canal becomes infected again, retreatment removes the old filling material, cleans the canals again and reseals them. Complex retreatments or root-end surgery may be referred to an endodontist, whose fees reflect that complexity.

What Is the Full Cost of Saving a Tooth?

The full cost of saving a tooth with a root canal usually includes the exam and X-rays, the root canal treatment, a temporary filling and the final restoration. For back teeth, the final restoration is often a crown, which can cost as much as or more than the root canal itself.

Back teeth that have had a root canal are more likely to fracture without a crown, because a large part of the tooth has been removed. Our article on whether you need a crown after a root canal explains when a crown is recommended, and our guide to dental crown cost in Ontario covers that part of the budget.

Does Insurance Cover Root Canal Treatment?

Most private dental plans in Ontario cover part of root canal treatment. Plans may classify it as basic or major services, which affects the percentage they pay. Annual maximums, deductibles and waiting periods can reduce coverage, and the crown afterward is usually a separate claim under major services.

Questions to ask your insurer:

• Is endodontic treatment covered as basic or major services, and at what percentage?
• How much of my annual maximum is left?
• Is there a waiting period for major services, such as crowns?
• Do I need a predetermination before treatment?

Your dental office can send a predetermination, which lists the procedure codes and fees so your insurer can tell you what it expects to pay. If the tooth is painful or infected, treatment may need to start before a predetermination comes back; ask your dentist about timing.

Does the CDCP Cover Root Canals?

Yes. The Canadian Dental Care Plan covers standard root canal treatment on front teeth, premolars and first and second molars without preauthorization, for eligible patients. Retreatment, root-end surgery and root canals on wisdom teeth need preauthorization. You may pay a co-payment depending on your adjusted family net income.

Key rules from the CDCP Dental Benefits Guide:

The CDCP also requires the tooth to have adequate gum and bone support and enough healthy structure to restore. The plan is for Canadian residents who have no access to private dental insurance and an adjusted family net income under $90,000. Our post on CDCP eligibility explains who qualifies.

Root Canal vs Extraction: How Do the Costs Compare?

An extraction usually costs less on the day than a root canal, but replacing the missing tooth with an implant or bridge usually costs more than saving it. Leaving a gap can also let neighbouring teeth drift and affect your bite. For many patients, saving a restorable tooth is the more economical long-term choice.

Not every tooth can or should be saved. A tooth with severe fractures, very little remaining structure or poor bone support may be better extracted. Your dentist can explain which option suits your tooth. See our guides to tooth extraction cost in Ontario and dental implant cost in Ontario to compare.

What Happens During a Root Canal Appointment?

A root canal usually takes one or two appointments. The tooth is numbed with local anesthetic, the dentist removes the inflamed or infected pulp, cleans and shapes the canals, then seals them and places a filling. Most people feel pressure rather than pain, and tenderness usually settles within a few days.

1. Numbing. Local anesthetic numbs the tooth and surrounding area.
2. Isolation. A thin rubber sheet, called a dental dam, keeps the tooth clean and dry.
3. Cleaning and shaping. Small instruments remove the pulp and shape each canal.
4. Sealing. The canals are filled and sealed to help prevent reinfection.
5. Restoration. A temporary or permanent filling goes in, and a crown is planned if needed.

Signs you may need a root canal

Common signs include pain that lingers after hot or cold, pain when biting, swelling near a tooth, a pimple-like bump on the gum and a tooth that has darkened. Some infected teeth cause no symptoms and are found only on X-rays, which is one reason regular check-ups help catch problems while they are simpler and less costly to treat.

Frequently Asked Questions

Why does a molar root canal cost more than a front tooth?

Molars usually have three or four canals, often curved or narrow, while front teeth often have one. More canals mean more time to locate, clean, shape and seal, and sometimes extra imaging. Molars also usually need a crown afterward, which adds to the total cost of saving the tooth.

Is it cheaper to pull a tooth than get a root canal?

On the day, an extraction usually costs less. But replacing the tooth later with an implant or bridge usually costs more than a root canal and crown. Leaving a gap can also affect your bite. Your dentist can help you compare the full costs for your situation.

Do I need a crown after a root canal?

Often, especially on back teeth. A root canal removes the inside of the tooth, and back teeth take heavy chewing forces, so a crown helps prevent fractures. Front teeth with enough remaining structure may only need a filling. Your dentist will recommend what suits the tooth.

Can I delay a root canal to save money?

Delaying is risky. An infected tooth usually gets worse, which can mean more pain, a larger infection, a more complex procedure or losing the tooth. If cost is the concern, ask about phasing treatment, insurance predeterminations or financing rather than waiting.

Why might my dentist refer me to an endodontist?

Complex cases such as retreatments, curved or calcified canals, or root-end surgery may be referred to an endodontist, a dentist with extra training in root canal treatment. Specialist fees are often higher, but referral helps match the case to the right care.
