As he was remarking how little tartar I had (as he always does), while scraping at my upper front teeth, his dental hook slipped and slammed into the part of the inside of my upper lip where it meets the gums. Not the SHARP part, just the curved back of the hook. It hurt enough to make it throb for a while and there was a little bleeding that stopped right away. "Oops, sorry," he said.
Then my smart and pretty dental assistant cleaned my teeth (okay, it's still Anya, hee). The throbbing went away, but after a few hours, my upper lip started to swell. Not a whole lot, but it's the kind of swelling that happens only to your lips. Those who have been hit in the face know what I am talking about. Your lips get stiff, swell, and then you have this goofy overbite look.
While mine is not as bad as it could be, and it's gone down since yesterday, it's still annoying. Sometimes I make a raspberry sound when I say the letter "P," and people ask if I have a huge zit under my mustache or something.
