Sometimes you may need to re-treat the nerve or roots of the tooth if the previous treatment was not successful or the treatment was not completed completely. Your need for re-treatment of the nerve or roots depends on the condition of the tooth and the type of symptoms you are experiencing.
If the root canal is re-treated, the dentist will examine the tooth and assess its condition to determine if it needs to be treated again. And when it is necessary to re-treat the nerve, the previous material that was used in the previous treatment will be removed, and the dental root will be cleaned well, and then the dental root will be filled with a new material.
In the case of re-treatment of the roots of the teeth, the dental root will be cleaned from the previous material and cleaned well, and then the dental root will be filled with a new material to prevent the return of infection.
Although re-treatment of the nerve or root can be very successful in many cases, it can be complex and take longer than the original treatment, and may require additional procedures to achieve a full recovery. Therefore, a specialist dentist should be consulted to determine whether the nerve or tooth roots should be re-treated in your case or not.
