The dental pulp cavity is divided into the pulp chamber and the root canal. There is a small hole at the root apex called the apical foramen;

[0003] The pulp tissue is located in the pulp cavity inside the tooth and is the only soft tissue in the tooth. Because the tooth is hard, the hard outer shell needs to be broken in order to remove the pulp tissue. The existing technology is to break or squeeze the tooth.
