Root canal treatment is needed when the nerve of your tooth has become
infected through decay or injury. An infected tooth may result in the
patient presenting with an abscess. The patient may complain of swelling
as well as pain which may be severe. The tooth will require root canal
therapy and if this is not done the infection will more than likely spread
to other teeth.
Root canal therapy will require at least two visits to the practice. On the
first visit the nerve of the tooth will be removed together with the tissue
associated with its blood supply, the pulp. Once the dentist is happy that the
source of the infection has been removed and any abscesses are drained, a
temporary filling will be installed. On the second visit the dentist will
complete the root canal treatment before permanently filling the tooth.
