Short answer
A root canal removes infected or damaged tissue from inside a tooth so the tooth can be saved. The inside of the tooth is cleaned, filled and sealed. It is done with local anesthetic to numb the area, and many teeth are then protected with a crown.
What is a root canal?
Inside each tooth is soft tissue called the pulp, which runs through narrow channels in the roots. If the pulp becomes infected or badly inflamed, the tooth can hurt and infection can spread. A root canal treats the inside of the tooth so it does not have to be removed.
Signs you may need one
- Severe or lasting tooth pain.
- Pain when you chew or put pressure on the tooth.
- Sensitivity to hot or cold that lingers.
- Swelling or a bump on the gum.
- A tooth that darkens.
Sometimes there are no signs. Only an exam and X-rays can confirm what is going on.
The procedure
- The tooth is numbed.
- The dentist makes a small opening and removes the infected or damaged pulp.
- The canals are cleaned and shaped.
- They are filled and sealed.
- The opening is closed with a filling.
The tooth often needs a crown afterwards to protect it.
Recovery and aftercare
- Do not chew on the tooth until numbness has worn off and until it is fully restored.
- Some soreness can last a few days. Over-the-counter pain relief as directed is often enough. Your dentist will advise.
- Brush and clean between your teeth as normal.
- Call the clinic if pain or swelling gets worse.
What are the alternatives?
The main alternative is removing the tooth. A missing tooth may then need to be replaced. Your dentist will explain the options, and what may happen if an infected tooth is left untreated.
