To cure the infection and save a tooth that is too decay o cracked, the dentist drills into the pulp chamber and removes the infected pulp by scraping it out of the root canals. Once this is done, the dentist fills the cavity with an inert material and seals up the opening. This procedure is known as root canal therapy. With the removal of nerves and blood supply from the tooth, it is best that the tooth is fitted with crown; this increases the prognosis of the tooth by six times.
For patients, root canal therapy is one of the most feared procedures in all of dentistry; however, dental professionals assert that modern root canal treatment is relatively painless because the pain can be controlled. Lidocaine is a commonly used local anaesthetic. Pain control medication may be used either before or after treatment.
