Why Root Canals Are Performed and How They Work

January 3, 2019

Has your dentist suggested a root canal treatment? Are you looking for information on root canal? Here’s a look:

The space inside your tooth which travels down the length of root is known as canal. On the basis of anatomy of the tooth, the tooth may have one or more canals.

Common Reasons for Root Canals

The canal in the tooth consists of pulp also known as the nerve that originates from the pulp chamber. Infection in the nerve will need you to have a root canal.

Common reasons for root canal are as follows:

  • Tooth decay is a common cause which infects the pulp of the tooth via enamel.
  • Tooth that has become abscessed because of the decay.
  • Nerves exposed due to chipped or broken tooth.
  • When the tooth is dying because of aging or trauma.

The procedure

Your root canal therapy may need only single or sometime multiple visits. Your dentist will inform in advance the number of appointments needed for root canal treatment. If you have an infection in mouth, you may be given antibiotics before completion of the procedure.

  • The Root canal Procedure begins by numbing your tooth. Then a dental X-ray of the tooth is taken which films the entire tooth for reference.
  • Then a rubber dam is placed in the mouth to keep it dry from saliva followed by disinfecting the inside of the tooth.
  • The dentist will then drill a hole in the area known as pulp chamber where the nerves are located.
  • Then the infected nerves and tissue will be removed. All the infected nerves must be removed to prevent the infection from appearing again.
  • Once the tooth is dried, gutta percha will be placed in your tooth for sealing.
  • Once the filling is placed in tooth, the dentist may or may not suggest for having a crown for the restored tooth. The nerve and blood supply is removed which can make the tooth brittle over the time so a crown will help in preserving it.
