Non-Surgical Root Canal Retreatment
In most cases, teeth that have had endodontic treatment can last just as long as your natural teeth. Occasionally, successfully treated teeth may become painful or diseased long after treatment if it has not healed properly, or if a new problem arises. It is always best to save your natural teeth whenever possible, so a retreatment may be needed.
A retreatment may require existing restorative materials to be removed (crown, post and core material, root filings, etc.) This allows access to the root canals so that they can be thoroughly cleaned and resealed. A temporary filling is then put into the crown until it can be fully restored by your general dentist within 2 weeks.
