Our teeth are made up of four different types of tissue: pulp, dentin, enamel & cementum. The pulp is at the center of the tooth and consists of nerves, blood vessels and connective tissue. These tissues within the pulp are what nourishes the tooth and keeps it alive and healthy.
When a cavity (hole) appears in our tooth, bacteria will start to enter. If left untreated, bacteria can infect the pulp (center) of the tooth and you will start to notice extreme sensitivity and pain.
In a bid to save the tooth, root canal treatment is required to clean out the bacteria and the infected pulp. The inside of the tooth is then prepared to allow for a root filling which will stop any further bacteria from entering the tooth.
