Root canal therapy is the treatment of teeth that have had nerve damage, whether it be by decay or trauma. Root canal therapy preserves the natural tooth and thus the natural bone level. It is always advisable, if possible, to save natural teeth as extracting them can cause issues with aesthetics and function.
Root canal therapy is typically done over a few visits depending on the number of nerves and severity of infection. Initially, the tooth is anaesthetised and an opening made though the crown, exposing the infected/damaged nerve. The root canal system is then cleaned out, enlarged and antimicrobial agents placed. X-rays will be taken throughout the procedure to ensure that the whole length of the root canal is cleaned. Finally, a natural rubber compound is placed in the root canal system to prevent reinfection.
