Radium jaw

Radium jaw is an occupational disease brought on by the ingestion and subsequent absorption of radium into the bones of radium dial painters and those consuming radium-laden patent medicines. The symptoms are necrosis of the mandible (lower jawbone) and the maxilla (upper jaw) as well as constant bleeding of the gums and (usually) after some time, severe distortion due to bone tumours and porosity of the lower jaw.
