IHS	Diagnosis	ICD-10
11.6	Headache attributed to disorder of teeth, jaws or related structures [K00-K14]	G44.846

Diagnostic criteria:

Headache accompanied by pain in the teeth and/or jaw(s) and fulfilling criteria C and D
Evidence of disorder of teeth, jaws or related structures
Headache and pain in teeth and/or jaw(s) develop in close temporal relation to the disorder
Headache and pain in teeth and/or jaw(s) resolve within 3 months after successful treatment of the disorder

Comment:

Disorders of the teeth usually cause toothache and/or facial pain, and those causing headache are rare. Pain from the teeth may be referred, however, and cause diffuse headache. The most common cause of headache is periodontitis or pericoronitis as the result of infection or traumatic irritation around a partially-erupted lower wisdom tooth.
