Endodontic treatment

Inside each tooth is the pulp which provides nutrients and nerves to the tooth, it runs like a thread down through the root. When the pulp is diseased or injured, the pulp tissue dies. There are numerous reasons why teeth need root canal treatment but the two most common causes are: Physical irritation of the nerve or pulp. Deep decay present in a tooth can physically irritate the nerve. Also, large or deep fillings that are close to the nerve can also cause nerve irritation. These fillings may have been placed a few days prior to the onset of symptoms. Conversely, the fillings may have been placed years prior to any symptoms of nerve irritation.

Trauma in the form of a physical blow to a tooth can cause nerve irritation. The trauma may have been recent or many years in the past. Also, trauma resulting in physical fracture of the tooth close to or near the nerve results in nerve damage. If you don’t remove the damaged nerve, your tooth gets infected and you can lose it. Some time ago, if you had a tooth with a diseased nerve, you’d probably lose that tooth. Today, with a special dental procedure called a root canal therapy you may save that tooth. Once it has been determined (with X-Rays and clinical examination) that root canal treatment is necessary, it will take one or more appointments to complete the therapy. It is very important that patients keep these appointments for treatments to be smooth and successful. Antibiotics and pain medication may be prescribed and it is essential that these medications be taken as directed.

After getting the tooth numb with strong anesthetic solutions and isolating the tooth with a rubber dam, an opening is made through the top portion of the tooth into the pulp. The pulp is then carefully removed and the root canal area inside your mouth is cleaned, enlarged, shaped and sterilized. In some cases, the root canal therapy may be completed in this one appointment by permanently filling and sealing the root canal area. In other cases, a temporary medication and filling is placed in the tooth at this time. Sometimes, if a tooth is badly infected, the tooth may be left open which allows the infection to drain. At the subsequent visit, the root canal is finished by permanently filling and sealing the root canal area inside the tooth. X-Rays are taken at various points during the procedure to ensure that all of the infected pulp is removed and that the whole canal is sealed upon completion of treatment. After the root canal treatment is completed, a permanent filling or restoration will need to be placed into the opening that was made in the tooth.
