What Causes Root Canal Infection?
The enamel of your tooth is hard but not impenetrable. The dentin layer beneath your tooth’s enamel consists of hollow canals leading to your tooth’s roots. The most exposed layers are the pulp chamber and the dental pulp. The pulp is the soft, living tissue inside a tooth containing blood vessels, soft tissues, and nerves.
When your teeth suffer damage that penetrates the enamel and reaches the dentin layer, bacteria can enter the inside layers of the teeth. Once bacteria reach your tooth’s canals, they begin destroying the pulp. The tissue becomes inflamed and irritated, which can then cause significant pain.
Eventually, bacteria can spread to the tooth’s root, leading to an abscess. It is a painful pocket of pus that forms to contain the bacteria. If not treated, the abscess grows more prominent and can even rupture. When this happens, it allows bacteria into the bloodstream, leading to inflammation of the blood vessels and severe health complications.
