After killing the nerve, the tooth will lose the blood transportation from the apical source, causing the tooth to become brittle with insufficient nutrients, and the tooth will lose its internal pain sensation.
1. Usually, we need to carry out root canal treatment to “kill” the nerve after pulpal nerve inflammation, and the main blood supply of the tooth is from the apical part of the root into the pulp cavity to nourish the tooth tissues, which is accompanied by the nerve in the pulp cavity, and the infected contents of the pulp cavity and the dentin wall need to be removed during root canal treatment, so the pulp cavity will lose its main blood supply and become brittle, and the fracture resistance will decrease significantly. As a result, the pulp chamber loses its main blood supply, becomes brittle and its fracture resistance decreases significantly.
2. In addition, the pain sensation associated with nerve control is lost, and the damage to the tooth is not well perceived. Therefore, crown restoration is usually required to protect the tooth;
The advantages of root canal treatment are far greater than the disadvantages. If left untreated, it will lead to aggravation of the condition and eventual extraction, and the treatment should not be abandoned because the tooth becomes brittle. It is recommended to go to the dentistry department of a regular hospital.
