I have two teeth that are really close together and one has a filling with a rough edge. Result: any time I shove floss in there, it gets shredded to bits and stuck between those teeth. Ew!

My hygienist suggests that, for those teeth, I can use a proxabrush (sp?), a waterpik, or a rubber pokey thing to get the part near the gums. I have a hard time remembering to have those things around, so I now have them in my desk, in my purse, and at home near my toothbrush.
