Explains sedation dentist marina del rey, while teeth are hard calcified objects, they are not completely solid. In the inner most aspect of every tooth there lies a hollow space which, when a tooth is healthy, contains the tooth's nerve tissue. The terms pulp chamber and root canal refer to various portions of this nerve area. The pulp chamber is a hollow space that lies more or less in the center of the tooth. Each tooth's nerve enters the tooth, in generalities, at the tip of its root(s). From this point the nerve then runs through the center of the root in small "root canals" which subsequently join up with the tooth's pulp chamber.
