Correct answer: CInternal inflammatory resorption

The 'pink tooth of Mummery' is caused by internal inflammatory root resorption, where granulation tissue within the pulp canal resorbs dentin from the internal surface. The vascular granulation tissue shows through the thinned, translucent crown, producing the characteristic pink discolouration. It often follows trauma with chronic pulpal inflammation. Treatment is root canal therapy if the tooth is salvageable; the resorption ceases once the pulp tissue is removed.
