Root canal therapy is often completed in one or more visits, depending on the severity of infection. At the start of treatment, your dentist may isolate the tooth with a rubber dam to prevent salivary contamination of the canal system and protect you from the irrigants used during the procedure. A temporary filling or crown is placed to protect the tooth between appointments.
After each appointment when anesthetic has been used, your lips, teeth and tongue may be numb for several hours after the appointment. Avoid any chewing until the numbness has completely worn off.
It's normal to experience some discomfort for several days after a root canal appointment, especially when chewing. To control discomfort, take pain medication as recommended. To further reduce pain and swelling rinse three times a day with warm salt water.
If antibiotics are prescribed, continue to take them as prescribed, even if all symptoms and signs of infection are gone. Since the tooth is very fragile following treatment avoid eating sticky and hard foods. Avoid chewing on that side until the permanent crown is placed. The permanent crown will protect the tooth from breaking in future.
