This is gonna sound silly to anyone who doesn't have some high dollar dental work in their mouths, but I have a little curved metal toothpick thingy on my keyring. Getting something stuck under a bridge, or elsewhere, can go from irritating to downright painful if not removed, and floss won't get under a bridge. Can't find a pic to show, but you can usually find them on the dental wall of a drugstore/WallyWorld type store...
