What is a root canal?
user
“Root canal” is a name given to a procedure that is performed to treat damage to the tooth root (a structure that anchors teeth to the jawbone) and the tooth pulp. It is a procedure in which the nerves and blood vessels at the center of the tooth are removed and the canal is cleaned and filled with a rubbery material called gutta percha. Gutta percha is the root-end of the same plant that rubber is obtained from.

Do root canals ever fail?
user
Root canal treatments are mostly successful at repairing damaged teeth. However, tooth loss, especially of molars, can occur with or without a root canal treatment. Studies have shown that up to 90 percent of root canals can be done with success. The results of the procedure are usually more successful if a periodontal or gum treatment is done before the procedure. In some cases, when a root canal fails, the tooth becomes infected and then needs to be extracted.
