Root canals are necessary when the pulp chamber of the tooth (which contains the blood vessels and nerve tissues) becomes diseased or has died, or if infection is present. The procedure itself is fairly simple. Root canal treatment involves cleaning out all of the diseased tissue of the pulp chamber and the canal within the tooth’s root. Next, we shape the canal and prepare it to be filled with a material which seals off the tip of the root, thereby not allowing any future problems such as infection.
A pulp cap is done to a tooth if the pulp chamber (which contains the blood vessels and nerve tissues) becomes exposed or nearly exposed due to deep decay or perhaps a fracture. The procedure involves covering the pulp with a protective material to protect the pulp from additional injury and to promote healing and repair.
