Root canal therapy

A root canal is a dental procedure used to save a tooth when the soft tissue or the pulp becomes inflamed or infected.

What happens during a root canal?

1. The dentist numbs the tooth and surrounding area.
2. A small opening is made in the tooth.
3. Infected or damaged pulp is removed.
4. The inside of the root canals is cleaned and disinfected.
5. The canals are filled and sealed.
6. The tooth is usually restored with a crown or filling to protect it from breaking.

Common causes include:

• Deep tooth decay
• A cracked or fractured tooth
• Repeated dental procedures on the same tooth
• Trauma to the tooth

Symptoms can include severe toothache, prolonged sensitivity to hot or cold, pain when biting, swelling, or a gum “pimple.” Sometimes an infected tooth causes no symptoms at all.

Does it hurt?

With modern local anesthesia, the procedure itself is usually not painful, although the tooth may be tender for a few days afterward. A root canal generally relieves the pain caused by the infection rather than causing it.

If you tell me whether you’re considering a root canal, have one scheduled, or are having pain after one, I can explain what to expect and what would be concerning.
