A Root Canal is essentially a filling that is deep inside your tooth. When a cavity becomes so large that the infection reaches the nerve of your tooth and becomes infected it is necessary to removed the blood supply and nerve from your tooth and that process is called a Root Canal.
Root Canals themselves are not painful, you are completely numb and they are just like any other dental procedure. They get their bad reputation from the toothache pain associated with the infection.
