Tooth remains

My teeth are in such a state!  I broke one last week which I have had repaired, but today a tooth that broke while I was in the UK has crumbled.  The dentist packed it with some sort of filling which fell out while I was talking today.

In the picture the bits of tooth look like something completely different. More like rocks in the sun.  It reminds me of recent pictures from Mars which some people say show fossilized lizards.

It also reminds me that I am getting old although the dentist seems to think my teeth will be good for another twenty years.  But maybe she was just being polite and hopeful!
