Wendy it sounds as if the dentist was talking about having implants or similar.

When I was in my early 30s I had a number of gold crowns which cost me an arm and a leg, we only have private dentists except at the hospital, and they are still going strong and I am told by the hospital dentist that my goldwork is top quality and will last until I die. I wonder if, had Ilived in the UK, whether NHS ones would have been of equal quality, I have my doubts otherwise why would the dentist wax lyrical about mine each time I see him?
