Reasons a Root Canal may have failed

A root canal is often necessary to stop the excruciating pain that is the result of an exposed nerve in a tooth. It is used to prevent infection around the teeth and to help save the tooth to be corrupted by the disease. The tooth's nerve is in a small room called the channel is in the center of the tooth. A root canal is performed when infection is present in the nerve or the channel is excavated to remove the infection. After the procedure, a crown is placed over the tooth to protect it. Any pain involved in a root canal is happening before the tooth is fixed. If you feel pain after a root canal is done, then it is a sign that the channel has failed.

There are many reasons why treatment may fail. The infection can not be completely removed or immune therapy. If so, the rest of the infection causes inflammation of the gums around the infected tooth. The dentist will complete another channel to make sure that the main purpose has been achieved and the problem is solved.

As mentioned above, for a root canal filling with a crown will be placed in the tooth. If the dentist uses a composite material to cover the tooth in place of a crown, any material remaining in the nerve of the tooth may start to rot and in turn create an infection. The pain caused by what may be light or a steady pace that can be felt throughout the head. If you experience a severe headache, it will remain until the channel has not been repaired. If a root canal fails, allows bacteria to the tooth and the tooth dry rot. Consequently, the tooth can become very fragile and can begin to crack and crumble if not treated immediately.

While the intense pain is diminished by an emergency channel and the patient feels relief, the procedure must be completed by the completion of another contract to return to the dentist and placed a crown on the tooth. The absence of pain in the interim does not mean that the tooth is hardened for the long term.
