Root canal treatment is used to treat a tooth that is severely damaged or infected. It involves local anesthesia, removing the injured or infected tissue (pulp) from inside the crown and root of the tooth and then disinfecting, filling, and sealing the canal. The tooth is then sealed with either a temporary or permanent filling. Root canal treatment is often used to prevent further spreading of infection surrounding the tooth. Sometimes, it can be required for other reasons to save and restore a tooth. Often, a crown is put into place over top of the tooth after the root canal is complete.
Root canal treatment may require a second visit to the dentist. Your tooth may feel tender for the first couple weeks after the treatment. However, if you experience bad pain or swelling, contact your dentist.
Root canal treatment does not prevent cavities or gum disease. Proper dental hygiene is essential for maintaining healthy teeth.
