Will the tooth need any special care or additional treatment after endodontic treatment?

You should not chew or bite on the treated tooth until you have had it restored by your dentist, particularly part of the tooth has been destroyed by cavity or trauma. The tooth without a crown or final restoration after root canal treatment is susceptible to leakage and fracture, so you should see your dentist for a final restoration as soon as possible. Placing a crown or final restoration is extremely important to ensure the long-term success of the root canal treatment. Practicing good oral hygiene, including brushing, flossing, and regular checkups and cleanings will also help you to keep the endodontically treated tooth for long time.

Most endodontically treated teeth last as long as other natural teeth. In a few cases, a tooth that has undergone endodontic treatment does not heal or the pain continues. Occasionally, the tooth may become painful or diseased months or even years after successful treatment. Often when this occurs, redoing the endodontic procedure (retreatment) or performing the root canal surgery (apicoectomy) can save the tooth.
