	Why Does A Tooth Require Root Canal Therapy?
	Root canal therapy is required when the pulp, which is a network of tissue fibers containing veins, arteries, and nerves becomes infected or inflammed.

	Bacteria:
		Bacteria, which is the most common cause of infection and inflammation, enters the pulp of the tooth through decay or through a crack. However, other factors may contribute, such as repeated dental procedures, or a blow or traumatic injury to the face. Swelling and discomfort may also occur when toxins from the bacteria leak out of the root end(s) and erode the supporting bone structure leading to an abscessed tooth.
