Following this the tooth is then restored with a filling or a crown. As a guide we recommend crowning back teeth following root canal treatment to prevent the tooth from cracking. If there is not a huge amount of tooth structure left following the root canal, a post and core may need to be placed to support a crown. After the final restoration is placed this tooth will function like any other tooth.
Despite the jokes about root canal treatment being painful, modern treatment is similar to having a normal filling done, however it takes a bit longer.
