In most cases, toothaches, or pain in the jaw bone, are caused by problems deep within the pulp of a tooth.  Dental pain can also be caused by cavitiesgum disease, the eruption of teeth, jaw disease or exposed tooth root.  Jaw pain resembling a toothache may also be a symptom of diseases of the heart, such as angina or a myocardial infarction (heart attack), due to referred pain.

The severity of a toothache can range from a mild discomfort to extreme pain, which can be either continual or sporadic.  The pain may be aggravated somewhat by chewing pressure or temperature changes.  Teeth effected by irreversible pulpitis or abscess will need either a root canal (endodontic) treatment or an extraction to alleviate the pain.
