J.,
I found a bunch of really disgusting pictures for you. http://images.search.yahoo.com/search/images?_adv_prop=im...
I don't even want dinner after seeing them. And I most certainly will bump my own tooth brushing up to 3 or 4 times a day now :) At 10, you can still bribe her, right? Wait, I believe we're supposed to say "use incentives" now. My daughter is only 6, but she wasn't brushing very well either. We made a simple chart on a dry erase board. We got her the light up (I think they're called Firefly) toothbrush that times her brushing for a minute or 2 with a flashing light, so she knows how long to spend on them. We got her a step stool so she can get right up in front of the mirror to watch herself brush them, too. If she passes our "tooth check" test before bed on the first try, she gets to mark off another square. Now that she's a pro at it, she'll get a square taken back if she fails our check and falls back to lazier habits. There are 20 squares (which might take 20 days or over a month to pass through) for her to fill before getting her incentive. We let her choose the incentive for each chart. Right now, it's an American Girl Doll outfit she wants. She is getting SO MUCH better at brushing her teeth because brushing well is finally becoming a habit for her. We're on the end of our 3rd 20-square chart (we started right after Christmas), and we don't even have to hover and remind her while she's brushing anymore. When we first started, though, either my husband or I brushed our own teeth with her, just to set the example of how it does take a few minutes, but it's really not a big deal. During that first chart, she decided she wanted to use our regular tooth paste, mint listerine, and our dental floss - because "it looked fun" when she watched us do it. Now, after morning coffee, I'll get the comment, "Eeeww...go brush your teeth! Your mouth smells disgusting, Mom!" Yep, that's my girl. I know your daughter is older, but maybe trying something like this is worth a shot. At the very least, take her to that website and try to gross her out :) Good luck!
