I recently moved and had to change dentist. I had my check up the other day and he was amazed that I'm 33 with no fillings.
He called in all ththe dental nurses to look at my mouth while I turned scarlet on the dentist chair
Surely it's not that uncommon 
Anyone else footloose and filling free in their thirties?
It did make me laugh because I've recently moved from the west of Scotland to "down south" and he did mention that the awful reputation of the west of Scotland Diet made him think we lived off deep fried mars bars
