Had A Filling Break

I just got back from the dentist. This is the piece that broke loose. (Much enlarged.)

It was an old metal filling, dating back at least to my teen years, if not pre-teen. I'm nearly forty so I guess my folks got their money's worth. The dentist put in a new-fangled type filling that matches the tooth. She put it in in layers with a syringe and the assistant held a UV light gun up to it to cure it. Pretty neat.
