A root canal is needed when there has been damage to a tooth that has reached the pulp (the inner area of the tooth). This can happen if the tooth has cracked or chipped, the pulp has become inflamed or infected as a result of repeated dental procedures, or a cavity has gone untreated.
The procedure can spark some anxiety, but it is meant to relieve pain and make a tooth healthy again. It starts with the application of an anesthetic to ensure that you don’t feel any pain. A hole is drilled into the crown (top) of the tooth in order to access the inside of the tooth. The dentist will use specialized tools to remove the decay from the inside of the tooth along with the pulp. The tooth is then cleaned thoroughly and filled with a synthetic material to maintain the tooth structure. A crown is used to cover the tooth and protect it.
