Root canal treatment otherwise known as endodontics, involves the removal of the pulp tissues that has become infected. Root canal treatment saves teeth that would otherwise have been extracted.
If the pulp becomes infected, the infection may spread through the root canal
system of the tooth. This may eventually lead to an abscess. If root canal
treatment is not carried out, the infection will spread and the tooth may
need to be taken out.
On the other hand, there may be no symptoms at all. If pulp inflammation or infection is left untreated, it can eventually cause pain, swelling and loss of the supporting bone.
