A person's front bottom teeth can hurt for a variety of reasons, including gum inflammation, a cavity, tooth decay, a cracked tooth, nerve root exposure or pulp inflammation. The treatment for a toothache of the bottom front teeth depends on the cause of the pain.
Pain in the teeth that occurs only momentarily when eating or drinking hot or cold foods might not signal anything wrong, according to the American Association of Endodontists. Lasting pain after eating or sharp pain when biting down on food can signal other issues, such as tooth decay or a cavity. In those cases, treatments like fillings or root canals might be necessary.
