Despite their bad reputation, root canals can be very beneficial. In many cases, a root canal can save a tooth that might have otherwise needed to be extracted. In a root canal, the dentist removes the infected tooth pulp from the center of the tooth, cleans the chamber, seals the inside of the tooth and fills it with a medicated material to replace the pulp. Often, the dentist will place a crown over the tooth to further protect it.

But new decay may attack the tooth if more of it is exposed by receding gums. Or, the dentist may miss some of the diseased pulp during the initial root canal. The crown may not be placed in time to prevent an infection, or the crown or even the tooth could become damaged. That will require a retreatment.

In a retreatment, our dentist, Dr. Praveen Mandera can reopen the tooth to access the interior. That may require removing the crown or post. After cleaning the tooth, the dentist may re-clean and carefully examine the root chamber for new damage. In some cases, you may require endodontic surgery. Otherwise, the filling and sealing can be replaced and you may need to make an appointment to have a new crown placed on the tooth.

The best way to protect your tooth is to practice good oral hygiene by brushing twice a day and flossing once a day. You should also see our dentist for regular cleanings and exams. It’s also a good idea to avoid hard foods, or chewing on objects that can damage your crown.
