Root Canal Treatment involves removing inflamed or damaged tissue from inside a tooth and cleaning, filling and sealing the remaining space.
The pulp, or soft inner tissue of your tooth, is normally surrounded and protected by a layer of dentin. Above the gumline, the dentin is protected by a layer of enamel; below the gumline, the dentin is covered by cementum. When a deep cavity, decay or crack destroys these protective layers, the pulp is exposed to the bacteria in your mouth. This can result in inflammation, infection and, eventually, necrosis (pulp death). A severe blow to the tooth can also damage the pulp. Irritants may then escape from the end of the root and cause a diseased area (apical lesion) in the bone.
Root canal treatment removes the damaged pulp and irritants which allows the bone surrounding the root end to repair and heal.
