Root canal treatment (also called a root canal) is done when decay will likely damage or has already killed a tooth. During a root canal, a dentist or endodontist removes the pulp from the center of a tooth and fills the pulp cavity. This can prevent the development of a painful infection in the pulp that may spread to other teeth. A root canal can also treat an infection that has developed into an abscessed tooth. This procedure can relieve toothache, stop infection, and promote healing.
Root canals allow the dentist remove the pulp, clean the canal and seal the tooth, effectively protecting and saving the tooth. After an opening is created through the crown of the tooth into the dental pulp chamber, the pulp is removed. The canal is cleaned out, and the pulp chamber is permanently filled. The dentist will proceed by putting in a temporary filling. Afterwards, the temporary filling will be replaced with a permanent filling or a crown, depending on the location of the tooth within the mouth.
