About the Treatment
Keeping a Tooth That Would Otherwise Need Removing
When the soft tissue inside a tooth (the pulp) becomes infected, the usual choices are root canal treatment or removing the tooth. Root canal treatment clears the infection from inside the tooth and keeps the tooth itself in place.
The infected pulp is removed, the canals inside the root are cleaned and shaped, and the space is sealed so bacteria cannot re-enter. Treatment is carried out under local anaesthetic, and most people find it comparable to having a filling.
A treated tooth is more brittle, so a back tooth normally needs a crown afterwards to stop it fracturing. We will tell you before we start whether yours is likely to.
Signs & Symptoms
Signs You May Need a Root Canal
These can point to infection or inflammation inside a tooth. They can also have other causes, so an examination is needed to know.
-
Pain when chewing or biting
Severe pain when you bite down or put pressure on the tooth.
-
Lingering sensitivity
Sensitivity to hot or cold that lasts after the food or drink has gone.
-
A darkened tooth
A tooth that has become darker or discoloured.
-
Swollen or tender gums
Swelling or tenderness in the gum near the tooth.
-
A pimple on the gum
A small bump on the gum that keeps coming back.
-
No symptoms at all
Sometimes an infection shows on an X-ray before it causes pain.
Swelling that is spreading towards your eye or neck, or trouble breathing or swallowing, needs urgent care. See what to do in a dental emergency.

What to Expect
The Root Canal Procedure
What happens from the first assessment through to restoring the tooth.
-
Examination and X-Rays
We assess the tooth and take digital X-rays to see the extent of the infection, and explain the options, including removal.
-
Local Anaesthetic
Local anaesthetic is given so the tooth and the gum around it are numb during treatment.
-
Cleaning and Shaping
The infected pulp is removed and the canals inside the root are cleaned and shaped.
-
Sealing and Restoration
The canals are sealed and the tooth is restored with a filling or a crown.
-
Afterwards
The toothache usually settles within a few days. Because a treated tooth is more brittle, a back tooth normally needs a crown to stop it fracturing.

Will I need a crown after a root canal?
