Q.
I was advised to have my gold crown removed (dentist said x-ray showed ‘a problem’). I’ve had the new crown about a year. The You & Yours programme about aluminum bronzes worried me as my crown is bronze coloured. Wrote to my dentist asking what metals were in my crown. She replied: zinc, silver, gold, palladium, indium and iridium. Because of my residual concern I would be grateful if you would confirm that this alloy would result in a bronze colour, and that there is no risk of the metals leaching.
