Nonodontogenic toothache

Toothache is a common complaint in the dental office. Most toothaches have their origin in the pulpal tissues or periodontal structures. These odontogenic pains are managed well and predictably by dental therapies. Nonodontogenic toothaches are often difficult to identify and can challenge the diagnostic ability of the clinician. The most important step toward proper management of toothache is to consider that the pain may not be of dental origin. Signs and symptoms suggestive of nonodontogenic toothache are as follows: 1. Inadequate local dental cause for the pain. 2. Stimulating, burning, nonpulsatile toothaches. 3. Constant, unremitting, nonvariable toothaches. 4. Persistent, recurrent toothaches over months or years. 5. Spontaneous multiple toothaches. 6. Local anesthetic blocking of the suspected tooth does not eliminate the pain. 7. Failure to respond to reasonable dental therapy of the tooth.
