In the event of the “nerve” of your tooth dying or becoming infected, your dentist may suggest a root filling (endodontics) as a way to save your tooth from extraction.  

Your dentist will use both instruments and disinfectants to clean the inside of your tooth, removing the infected nerve tissue and bacteria. The space would then be filled to seal your tooth to prevent further infection.

As a result of previous damage and treatment to your tooth it may be weaker. To manage this your dentist may advise a crown or onlay over the tooth after the root filling is completed.
