Dentists are trained to provide treatment for patients with straightfo
rward problems that respond to routine therapy and do not recur. Howev
er, patients may present to dentists and complain solely of physical s
ymptoms such as toothache, headache, and facial pain: only after much
inappropriate treatment these symptons are revealed to be due to emoti
onal disturbance. The dentist may spend hours investigating such patie
nts, in some of whom dental pathology may be present, but the symptoms
and ensuing disability cannot be satisfactorily explained as a result
. There are other patients who are preoccupied by physical symptoms or
by their appearance. In others, anxiety may manifest itself as a phob
ia, or a dysmorphic concern about certain aspects of their appearance.
