The type of treatment you have for toothache /sensitivity/swelling will depend on the cause of the pain, so your dentist will examine your mouth and may carry out an X-ray to try to identify the problem.
?If your toothache / sensitivity/swelling is caused by tooth decay, your dentist will remove the decayed area and replace it with a filling.
?If your toothache / sensitivity/swelling is caused by a loose or broken filling, the filling will be taken out, any decay will be removed and a new filling put in place.
?If the pulp inside your tooth is infected, you may need root canal treatment. This procedure involves removing the infected pulp and then inserting a special type of filling to seal the tooth and prevent re-infection.
?If your toothache / sensitivity/swelling can't be treated using these methods, or if your tooth is impacted (wedged between another tooth and your jaw), it may need to be removed.
