dentists and how to be very stupid

The dentist said the tooth is going to need a root canal job. If the tooth wasn't one I use, he'd have removed it alltogether. It's going to take three sessions including the one today...

It's got entibiotic and a temporary filling in at the moment. At least, it had...

I was just flossing my teeth to get a bit of food out, and without thinking, I automatically started working round the teeth where bits often stick, and I've just pinged out part of the temporary filling!

I'm not sure if what's left will last until the 14th when I'm supposed to be getting the next part of the job done.
