Whether pulp necrosis is serious or not varies from person to person. From the doctor’s point of view, pulp necrosis is the most basic lesion of the dental pulp, which can be treated. If you don’t take care of it, it will slowly develop and become very serious, and may even have apical inflammation, or even the inflammation may affect other teeth if it continues to expand. In more serious cases, if there is further resorption of the root or other conditions, the entire tooth may not be preserved. Therefore, although pulp necrosis is not a very serious disease from the clinical point of view, but if not treated, it is very harmful, must pay attention to pulp necrosis.
