While root canals might seem like more trouble than they are worth, in some situations they can be quite necessary and can actually be lifesavers. In fact, a young Egyptian pharaoh by the name of Tut-ankh-amun, otherwise known as King Tut, lost his life to an infected tooth and bad dental hygiene a few millennia ago.
An interesting thing about root canal treatments is that it is not nearly as painful as the time leading up to the procedure. Once you get the root canal done, you, your teeth and mouth are going to feel much better.
