A damaged dental pulp can lead to the growth of bacteria in the tooth. A tooth root infection may result in an abscess, a pocket of pus-forming at the end of the root. Without treatment, an infection can spread and result in an abscess. These can cause pain, tenderness, and swelling around the tooth and jaw.
It is possible to treat irreversible pulp damage by either removing the dead or diseased pulp tissue with root canal treatment, or removing the entire tooth. If possible, root canal therapy is far superior to tooth extraction, as it is capable of prolonging the life of the natural tooth. The chances of it healing well are high if you restore it immediately after treatment.
When a root canal treatment is performed, a small hole is drilled into the top surface of the tooth to gain access to the canal space. After this step, the root canals, each of which could have more than one, are cleaned of the dead or diseased pulp tissue. The process is known as pulpectomy. It is necessary to disinfect the inside of the tooth before sealing it with a biocompatible filling material and closing the access hole.
We always use local anesthesia and use a barrier called a dental dam in order to isolate the tooth from the mouth. For your safety, dental dams prevent mouth bacteria from recontaminating your root canals during the treatment. If a crown is recommended after root canal treatment, the seal over the root filling will be preserved, and the dental structure will be protected from fracture.
