‘Root canal’ sounds scary, but it’s a routine procedure that saves an infected tooth and relieves pain. Here’s what it costs in 2026 and what actually happens.

Root canal cost by tooth

What to expect

The dentist or endodontist numbs the tooth, removes the infected pulp, cleans and seals the inside, and usually places a temporary filling. A permanent crown often follows to protect the tooth. Most people compare the discomfort to getting a filling — the procedure relieves the severe pain an infection causes rather than creating it.

Is it worth it vs extraction?

Pulling the tooth is cheaper upfront, but replacing it later with an implant or bridge usually costs more overall, and keeping your natural tooth is generally best for function and bone. Insurance often covers part of a root canal as a ‘basic’ or ‘major’ procedure. Treating an infection promptly also prevents it from spreading.

Don’t delay an infected tooth

When a tooth needs a root canal, waiting rarely saves money and can cost you the tooth. An untreated infection doesn’t resolve on its own — it tends to worsen, can cause an abscess, and in rare cases spreads to become a serious health problem. As the infection progresses, the tooth may become unsavable, leaving extraction (and the cost of replacing it later) as the only option. If cost is the barrier, talk to the dentist about phasing the treatment, financing, or a dental school, rather than ignoring the problem. In the meantime, over-the-counter pain relief and avoiding very hot, cold, or hard foods on that side can help, but these are stopgaps, not solutions. Seek prompt care if you develop facial swelling, fever, or severe, spreading pain, which can signal a worsening infection. The encouraging part is that a timely root canal followed by a crown usually preserves your natural tooth for many years — a far better outcome than losing it. Treating it early keeps both your tooth and your costs under control.

Frequently asked questions

Does a root canal hurt?

Modern root canals are done under anesthesia and typically feel like getting a filling. They relieve the pain of the infection, not cause it.

Why do I need a crown after a root canal?

A treated tooth becomes more brittle, so a crown protects it from cracking, especially on molars that do heavy chewing.

Root canal or extraction — which is better?

Saving the tooth with a root canal is usually best long-term; extraction is cheaper upfront but replacing the tooth later often costs more.
