What happens during a root canal?

Exam and X-rays

The dentist checks the tooth, surrounding bone, bite, and symptoms.

Local anesthetic

The area is numbed so treatment is focused on comfort and pain relief.

Root canal FAQs

What are root canals?

A root canal is a tooth-saving dental procedure that removes infected or inflamed pulp from inside a tooth, disinfects the canals, seals the space, and usually protects the tooth with a crown.

Do root canals hurt?

Most root canal treatment is done with local anesthetic, so the goal is to relieve tooth pain rather than cause it. Soreness for a few days afterward is common.

How do I know if I need one?

Common warning signs include lingering temperature sensitivity, pain when biting, swelling, a gum pimple, deep decay, a cracked tooth, or a darkened tooth after trauma.

Is a crown always needed after a root canal?

Back teeth and heavily restored teeth often need a crown because they handle chewing forces. Front teeth may not always need one, depending on remaining tooth structure.

Tooth pain should not stay a mystery.
