Endodontic (pulp) treatment involves the partial or total removal of infected or injured pulp tissue. The pulp chamber and root canal(s) are then cleaned and sealed.

Purpose

Points to note on pulp treatment
  • It requires a few visits to the dentist to complete a pulp treatment; remember to keep the appointments for treatments.

  • See the dentist immediately if the temporary filling material has fallen off, in order to prevent bacteria in the saliva from entering the pulp chamber.

  • If local anaesthesia is used, do not bite your lips or tongue before the numbness has completely worn off.
