A root canal is a treatment to repair and save a badly damaged or infected tooth. The procedure involves removing the damaged area of the tooth (the pulp), cleaning and disinfecting it and then filling and sealing it.:
What is Root Canal?
When a tooth is badly decayed or infected a dentist might recommend a root canal. People generally know they need a root canal because they feel a sharp pain and that is the nerves signaling it’s time for it to come out by then the infection reached the root. During a root canal the nerve of the tooth and the pulp are removed and the dentist cleans and seals the root of the teeth.
Some say that the root canal is painful but with the local anesthetic applied you generally feel no pain. The majority of the pain is what you experience from the wait of getting the infected or decayed tooth removed. After the root canal the dentist will use a crown or filling for protection. You can go back to chewing, biting and no one will notice the difference.
