After Completion of Endodontic Treatment FAQ

What should I expect after my endodontic treatment?

Endodontic treatment has now been completed. The root canal system has been permanently sealed. However, the outer surface is sealed with a temporary restoration. A follow-up restoration must be placed to protect your tooth against fracture and decay. Please telephone your restorative dentist for an appointment. A complete report of treatment will be sent to your restorative dentist. Included in your treatment is a follow-up examination to evaluate the progress of healing. This appointment will require only a few minutes and no additional fee will be charged for the first check-up visit. Please call for an appointment during the following month.

Your tooth is more prone to fracture immediately after endodontic treatment. You should chew on the other side until your restorative dentist has placed a core build-up and a protective restoration, usually a crown. If your tooth’s strength is seriously compromised, Dr. Lundgren or your restorative dentist may place a post and core build-up inside the tooth. Your restorative dentist and endodontist will determine the appropriate restoration to best protect your tooth.


  • DO NOT eat anything for 1 hour to allow temporary filling material placed in your tooth to set completely. It is normal for a thin layer of this filling to wear away between appointments.  However, if you think the entire filling has come out, please contact the office.
  • DO NOT drink any hot beverages and avoid eating until the numbness in your mouth wears off. This will prevent you from biting your cheek or tongue.
  • DO brush your teeth as you normally would. However, you should AVOID using retainers, mouth guards and partial dentures for 3 days after your procedure to prevent increased soreness.


  • Visible swelling inside or outside of your mouth
  • An allergic reaction to medication, including rash, hives or itching (nausea is not an allergic reaction)
  • A return of original symptoms
  • Your bite feels uneven, or your temporary filling comes out.


The root canal treatment is only one step in returning your tooth to full function.  A proper final restoration of the tooth is extremely important in ensuring long-term success.  Contact your dentist as soon as possible to arrange your next appointment.  You should see them 1-4 weeks after the root canal is completed.
