A root canal treatment may take one or several visits, depending on the complexity of the anatomy of the canal and the magnitude of the damage to the pulp.
Sometimes, if the infection has spread from the tooth to the bone – causing an abscess – the infection should be drained until the canal is sealed.
Your tooth can remain sensitive 1 to 2 weeks after treatment. Intense pain and inflammation are rarely experienced. If this is the case, you must call your dentist as soon as possible.
To keep the look and function of a natural tooth as much as possible, your tooth must be restored using a filling or a crown.
The restoration type will depend on the strength of what remains of the treated tooth. A posterior tooth will probably receive a crown because more pressure is exerted on these teeth when you chew. If too much of the natural tooth is missing, your dentist may use a dental post to hold the crown in place. A discoloured tooth can be either bleached or covered with a crown or a veneer.
