What is a Root Canal?
When you are told you need a root canal, it is generally because the nerve in your tooth has been damaged and is starting to die, or in some cases has slowly gone bad over time. This can happen due to decay in the tooth that has reached the nerve, or trauma from a blow to the tooth or in an accident where the tooth has been hit. Also sometimes a tooth can develop a crack that can reach the nerve and allow bacteria from your mouth to enter through the crack into the nerve and cause it to go bad. Many times there is pain, or sensitivity to hot or cold things during this degenerative process, but not always.
