A few days ago, a bit of one of my back teeth fell out. So I saved it in a jar, and today I took it to the dentist. He had a look at it, and reckoned that it was filling, not tooth, which is very good news.
Then he sat me down, shoved things in my mouth, called for Polyfiller (or whatever it is they use) and refilled the tooth. No pain, no hassle, ten minutes, and there wasn't even any charge, because I'd been there less than two months ago to have my bridge put in (which is working very well, giving me a new front tooth).
I love the NHS.
