Treatment that cleans infected or inflamed tissue from inside a tooth so that the tooth can be kept.
What it involves
The pulp inside a tooth can become infected or damaged. Root canal treatment removes it, cleans and shapes the canals and seals them. It aims to save a tooth that would otherwise need extracting. A crown is often fitted afterwards to protect the tooth.
Who it suits
Considered for a tooth with deep decay, an abscess, a crack that reaches the nerve or damage from injury. The tooth must be restorable. If the tooth is too damaged or the root is fractured, extraction may be advised.
How it usually works
Under local anaesthetic the dentist opens the tooth, removes the pulp, cleans the canals with fine instruments and irrigants, then fills and seals them. Treatment may take one or more visits. A permanent filling or crown follows.
Risks and things to consider
Canals can be complex and infection can persist or return, sometimes needing retreatment or a small surgery at the root tip. The treated tooth is more brittle and usually needs a crown. Soreness for a few days is common.
Questions to ask before you decide
What are the chances this tooth can be saved? Will I need a crown, and is it included? What are the options if the infection comes back? Is a specialist involved for difficult cases?
