After Completion of 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.

What should I expect following endodontic treatment?

The root canal system inside your tooth has been thoroughly cleaned, and the irritated tissue and bacteria that have caused you to need root canal treatment are gone. It is normal to feel some tenderness in the area over the next few days as your body undergoes the natural healing process. You may also feel some tenderness in your jaw from keeping it open for an extended period of time. These symptoms are temporary and usually respond very well to over-the-counter pain medications. It is important for you to follow the instructions on how to take these medications. Remember that narcotic medications, if prescribed, may make you drowsy, and caution should be exercised in operating dangerous machinery or driving a car after taking them. Your tooth may continue to feel slightly different from your other teeth for some time after your root canal treatment has been completed. However, if you have severe pain or pressure that lasts more than a few days, contact your endodontist.

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, your endodontist or 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.

Are There Any Potential Problems After Treatment?

  • Lower teeth and nerve injury. There is a slight possibility that nerve injury can occur during root canal surgery to the lower posterior teeth. Your endodontist is trained to assess this possibility prior to treatment and will advise you accordingly. For lower posterior teeth, the root tips may be near a nerve that supplies feeling to the lip, chin and gums. Your endodontist is trained to design your surgery to minimize the chances of damaging this nerve. Rarely, this nerve can become irritated during the process of surgery. In these cases, when the local anesthesia wears off, you may experience tingling, altered sensation or, in rare cases a complete lack of feeling in the affected tissues. Should this occur, it is usually temporary and will resolve over a period of days, weeks or months. In rare cases, these changes can be permanent and/or painful.
  • Upper teeth and sinus communication. The upper teeth are situated near your sinuses, and root canal surgery can result in a communication between your mouth and the adjacent sinus. Should this complication occur, it will usually heal spontaneously. We will give you special instructions if this is apparent at the time of surgery. We prefer that you don’t blow your nose for two to three days after surgery. If you have to sneeze, you should sneeze with an open mouth into a tissue. You should not create any pressure in the sinus area. If you sense a complication after surgery, please contact us.
  • Post-operative infections. Post-operative infections occasionally occur. This usually requires just an office visit and examination. Many times placing you on an antibiotic for one week will take care of the infection Occasionally, other follow-up procedures will be needed.

What the Future Holds


The tooth that has had appropriate endodontic treatment followed by a proper restoration can last as long as your other natural teeth. After the tooth has been restored, you need only practice good oral hygiene, including brushing, flossing, regular checkups and cleanings. Your dentist may periodically x-ray the tooth to ensure that healing has occurred. Occasionally, a tooth that has undergone endodontic treatment does not heal or pain continues. At times, the tooth may become painful or diseased months or even years after successful treatment. Often when this occurs, repeating the endodontic procedure can save the tooth.
