Root canal treatment is the treatment of a tooth that is sick, abscessed, severally broken, too long and in the way of the bite, or hurting due to issues that have affected the entire tooth. In comfort, a small entry is made into the tooth and the little tunnels or canals (where the nerve and blood vessels live) inside the tooth are cleaned and reshaped. A filling is placed inside these little canals to seal them off from germs (hence the term “root canal filling”).
Most of the time a root canal filling is the only treatment that can help save a tooth with the aforementioned conditions. A crown is then often recommended as the final restoration.
