When is endodontic retreatment needed?

Teeth that have had endodontic treatment will last just as long as natural teeth, with the proper care. Sometimes, a treated tooth doesn't heal or continues to be painful. This pain can happen months or even years following endodontic treatment. If this occurs, endodontic retreatment may be required.

Failure to heal properly can occur if:

  • Thin or curved canals weren't initially treated
  • Twisted or complex canals were not discovered at time of initial treatment
  • The placement of a crown or restoration did not occur within the proper amount of time after the initial endodontic procedure
  • The inside of the tooth was not protected from saliva by the crown or restoration

Occasionally, new problems can impact a tooth that was previously treated and successful:

  • Root canal filling material can be exposed by a new cavity and lead to infection
  • Fillings or crowns that become cracked or loose filling may expose the tooth to new infection

If a second treatment or "retreatment" is determined to be the solution, your endodontist will reopen the area to access the filling material in the original root canal. This material is then removed to expose the root canal. The canal of your tooth will then be thoroughly cleaned and examined. The your endodontist will fill and seal the canal of the tooth and place a temporary filling in it. A new restoration or crown should return it to a functioning, comfortable state.
