Saveyour tooth first

You’ve probably already tried waiting it out or taking painkillers. A tooth with an infected nerve doesn’t heal on its own, so the pain keeps coming back.

Our dentists examine the tooth first and start with the smallest treatment that fixes the problem. When your tooth can be saved, a root canal keeps it, and extraction stays the last option. Browse our full list of dental services if you have other concerns.

What is root canal therapy?

Root canal therapy removes the damaged nerve tissue (the pulp) inside your tooth, cleans the space, and seals it so bacteria can’t get back in. It’s part of the care we offer in General Dentistry.

Deep decay, a crack, or repeated work on the same tooth can infect the pulp. The treatment feels like a long filling visit, and it ends the infection that’s causing your pain.

Signs you may needa root canal

You may need a root canal if one tooth hurts when you bite down, or if hot and cold sensitivity lingers after the food is gone. Our dentists confirm it with an exam and x-rays.

ZSharp or throbbing pain in one tooth, especially when chewing
ZHot or cold sensitivity that lingers
ZSwelling or tenderness in the gum near one tooth
ZA pimple-like bump on the gum that comes and goes
ZA tooth that looks darker than its neighbours
ZAn old filling or crown that has started to ache again

Some infected teeth don’t hurt at all. That’s why an exam matters even when the tooth feels fine.

Root canal or extraction?

A root canal keeps your natural tooth, and that tooth keeps supporting your bite and holding its neighbours in place. Pulling the tooth often means a replacement later, such as a dental implant.

Extraction makes sense when a tooth cracks below the gumline or can’t be restored. In that case, our dentists walk you through your options, including a dental bridge, before you decide.

Mississauga root canal therapy FAQ

Does a root canal hurt?

No, the root canal itself shouldn’t hurt, because your dentist numbs the tooth first. The pain most people remember comes from the infection, and the treatment stops it. If you feel anxious, ask about nitrous oxide sedation.

How long does a root canal take?

Your dentist gives you the number of visits after the exam and x-rays, because it depends on the tooth and how far the infection has spread. We offer same-day emergency visits, so a dentist can examine a painful tooth quickly.

How much does a root canal cost in Mississauga?

The cost depends on which tooth needs treatment and whether it needs a crown afterward. We accept cash and major credit cards and work with most dental insurance plans. Fill out the insurance form on our new patients page, or call (905) 814-1600 and we’ll check your benefits for you.

Will I need a crown after a root canal?

Often, yes. A tooth can become more brittle after the nerve is removed, so your dentist usually places a filling or crown to protect it.

How do I know if I need a root canal or just a filling?

A filling treats decay that hasn’t reached the nerve, and a root canal treats a nerve that’s infected or inflamed. Your dentist uses an exam and x-rays to tell which one your tooth needs.

What happens if I don't get a root canal?

An infected tooth doesn’t heal on its own. The infection usually spreads, which brings more pain and swelling and a higher chance you lose the tooth.

Can a root canal fail?

It’s uncommon, but a treated tooth can get reinfected if the seal breaks down over time. If pain or swelling comes back, call us, and we’ll examine the tooth.
