The aim of root canal treatment is not to put you in immense pain. Instead, the root canal treatment is to save the tooth that is severely damaged or decayed. Generally, root canal treatment is required when the infection to the tooth is spread deep into the root of the tooth.
Root canal treatment is a procedure used to repair and save a badly decayed tooth. During root canal treatment, the nerve and pulp are removed, cleaned and sealed. Without the root canal treatment, the tissue surrounding the tooth will get infected and results in abscess formation.
