Root Canal in a Nutshell
Within the root of your teeth, you have a substance called the pulp. The pulp is a tissue that contains blood vessels, nerves, and connective tissues. During growth, our teeth need pulp to develop, however, an adult tooth can survive without the pulp.
When bacteria break through your enamel, it then infects and inflames the internal pulp; this is what results in the pain you feel when you need root canal treatment. When Dr. Crosby performs a root canal, he drills into the root of your tooth to remove all infected pulp and bacteria, saving the natural tooth.
