Root Canal Procedure
Root canal treatment is very common and it is almost the last line of defence to save a tooth, rather than having it extracted.
Broadly speaking, when the nerve of a tooth becomes affected and causes pain, the only way to get rid of the pain is to remove the nerve of the tooth. This in essence is what a root canal procedure involves.
The dentist makes a small hole in the tooth, finds the nerve and takes it out, then cleans the inside of the tooth thoroughly and fills it up to ensure that the tooth is completely sealed off.
Root canal treatment is carried out under local anaesthetic and so in theory you will not feel any pain during the procedure.
However, in some cases the nerve can be so severely affected that once the dentist tries to remove the nerve during the first cleaning stage of the root canal procedure it can start to feel a bit uncomfortable. If this is the case, tell your dentist and more anaesthetic may be required but this time the dentist may place it directly into the tooth and into the remaining nerve inside the tooth. This should make the procedure a lot more comfortable.
