Oral B Brush Ups...Rock! I used to travel a lot to nasty places and that's why I first bought them. This way I didn't have to brush my teeth with tap water (If I had bottled I would use it of course). I now keep them in my briefcase for a quick after lunch freshup, especially on the road. I don't like breath mints so I find them an awesome altenative. Yes, they are no good with steak and other stick in your teeth kinds of foods but they are great for getting rid of tartar that has not yet hardened near your gums. If you don't have the chance to brush after lunch or other meal I highly recommend them!
