Finally.

The razor-bite pain in my mouth came to an end fairly quickly once the tooth shard had worked its way out of the fleshy raw hole it was hiding in.

Funny how I went back to the dentist, who syringed the hole clean and told me it all looked well, but didn't manage to see the sharp tooth splinter of mouth evil.

Thank the tooth-fairy it came out of its own accord. One morning over breakfast. I dropped it on the floor and my friend's dog licked it up with glee.
