Endodontics treats the inside of the tooth: the pulp, often called the nerve, and the root canals. The aim is to save your tooth, even when the pulp is affected.
When is it needed?
When the pulp is irreversibly inflamed (spontaneous pain, pain that wakes you at night, lasting sensitivity to heat), when it is necrotic, in case of an abscess, or after a blow to the tooth.
Root canal treatment
Under local anaesthetic, the pulp is removed completely. The canals are cleaned, disinfected and shaped, then sealed. An X-ray checks the result. Treatment takes one or two appointments depending on the case.
After treatment
Some discomfort when chewing for a few days is normal. A root-treated tooth is more fragile: it must then be restored with a filling, an onlay or a crown, depending on how much is left.
Retreatment
If a root-treated tooth becomes infected again, the treatment can often be redone: this is called endodontic retreatment.
A living tooth is always better
Whenever possible, root canal treatment is avoided: with deep decay and a pulp that is still healthy, Biodentine can keep the tooth alive (see the guide on tooth decay).
