ABSTRACT
This chapter presents a discussion on the causes, diagnosis, and investigation of symptoms related to mouth. It provides a general practitioner overview, differential diagnosis, possible investigations, and top tips for dealing with oral related symptoms in patients. The symptoms discussed are bad breath, bleeding or painful gums, mouth lumps and marks, mouth ulcers, and painful tongue. The differential diagnosis includes common, occasional, and rare causes of the symptoms. Pain in the tongue is usually caused by something immediately apparent on examination, but there are a few less obvious causes. This is something much more likely to be seen by a dentist, but is not strictly dental and therefore a working knowledge of the symptom is firmly within the general practitioner remit.
