Endodontic Retreatment is a procedure that involves the soft inner of the teeth which is also called as the pulp. When your teeth have had root canal (endodontic) treatment, it can last as long as other natural teeth. However, in some cases, a tooth that has received endodontic treatment fails to heal. The tooth becomes painful or diseased months or even years after successful treatment. If your tooth continues to develop new problems, endodontic retreatment should be made for the possibility of saving your tooth.
All dentists are trained in diagnose and treatment but not all teeth can be treated the same way because some teeth are very difficult to diagnose. This is where you will be referred to an endodontic specialist to further check underlying problems of your teeth. In addition to general dental knowledge, Dentist studied two or more years of education for an Endodontic Retreatment Education. They study root canal techniques and procedures in greater depth, for treatment and diagnosis of difficult cases that is why for many reason, many dentists preferred to refer their patients to Dentists.
A tooth may not heal as expected after initial treatment for several reasons such as:
Before proceeding with the treatment, the Dentist will discuss your options. If you agree in doing the retreatment, the Dentist will reopen your tooth to gain access to the root canal filling material. Complex, restorative materials, post and core material must be disassembled and removed to permit access to the root canal. After removing the canal filling, the canals will be cleaned and the Dentist will carefully examine your tooth checking if additional treatment is required. When cleaning is done, the Dentist will fill and seal the canals and place a temporary filling in the tooth. If the canals are abnoramlly narrow or blocked, your Dentist may suggest endodontic surgery. This surgery involves making an incision to allow the other end of the root to be sealed. After your Dentist completes retreatment, you will need to return to your dentist as soon as possible to have a new crown or other restoration placed on the tooth to protect and restore it to its full function.
A tooth that was treated by an endodontic retreatment can function well for many years even for a lifetime. Here are other means of techniques or advance technology that may be able to save your tooth which may not have been available when you had your first procedure. The only other alternative to retreatment or failing endodontics ultimately is extraction of the tooth. It will then need to be replaced with an implant, bridge or removable partial denture to restore chewing function and aesthetics and importantly, to prevent adjacent teeth from shifting. Because these options require on adjacent healthy teeth, they can be more costly and time consuming than retreatment and restoration of the natural tooth.
