Root canal therapy is a treatment for an infected or necrotic ‘pulp’ inside a tooth. Dental Pulp is the name given to the soft tissue inside the channels in the roots of your teeth. It consists of blood vessels, fibres, and the nerves. The commonest cause of damage to the pulp is deep tooth decay which leads to inflammation and infection inside the tooth. This may spread to the tip of the root and into the bone, causing an abscess. Root canal therapy is a treatment to remove the infection from inside the pulp and surrounding tissues.
Root canals are caused by deep decay, trauma, cracks, heavy wear, leaking fillings and gum disease.
