Pain can be referred from a distant source. It is often helpful to record the pain diagnosis profile and location of the pain diagrammatically both intraorally and extraorally in the notes by shading or drawing in pain locations at the same time. There are occasions, as happens with trigeminal neuropathic orofacial pain, where the orofacial pain can move to other parts of the body. There are also occasions where orofacial pain is a symptom of a more general condition where symptoms are experienced in parts of the body remote from the orofacial region. Cracked teeth and loose restorations can also be described in this way, but can be differentiated from soft tissue pain by pressing on the soft tissues as described above. In the absence of obvious periapical involvement, check for periodontal problems, history of trauma, occlusal trauma or vertical root fracture.
