Pink Tooth of Mummery

A rare lesion consisting in internal resorption of a tooth, initiated by inflammatory hyperplasia of the pulp and haemorrhage, usually not associated with caries; the condition may appear as a pinkish area on the crown and, because the lesion is caused by osteoclasts, is known as an osteoclastoma; if detected early, ‘root canal’ therapy can salvage the tooth, otherwise it requires extraction
