Root canal treatment is used to save a decaying tooth by maintaining the structure of the tooth in order to avoid extraction. Severe toothache caused by infection or damaged roots can indicated the need for root canal treatment. Fortunately, the treatment is virtually pain-free and usually only requires two visits. During the treatment, the canals inside the tooth are cleaned and disinfected. After this, an internal filling is placed within the roots to prevent bacteria from entering in the future. The tooth is then sealed with a restoration designed to strengthen the tooth and further reduce the risk of decay.
Root canal treatment has a high success rate but it is essential that you maintain good oral hygiene habits after treatment to keep the tooth healthy.
