Post-operative Instructions for Root Canal Treatment

  • Root canal therapy often takes two or more appointments to complete. A temporary filling or provisional crown is placed to protect the tooth between appointments. After each appointment when anaesthetic has been used, your lips, teeth and tongue may be numb for several hours after the appointment. Avoid chewing until the numbness has completely worn off.
  • Between appointments it is common (and not a problem) for a small portion of your temporary filling to wear away or break off. If the entire filling falls out, or the provisional crown comes off, call us so it can be replaced.
  • 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.
  • If antibiotics are prescribed, continue taking them as prescribed, even if all symptoms and signs of infection are gone. To protect the tooth and help keep your temporary in place, avoid eating sticky foods (especially gum), hard foods and if possible chew on the opposite side of your mouth. It’s important to continue to brush and floss normally.
  • After the completion of root canal therapy it is strongly advised that we place a crown to protect the remaining tooth structure. As we discussed prior to root canal treatment starting – root treated teeth are more brittle than non-root filled teeth and are more likely to split, resulting in the loss of the tooth. The placing of a crown reduces this risk considerably.

If you have persistent swelling or pain, or you have any other questions or concerns, please call the office.
