Not that I have halitosis or anything, but sometimes, especially in the morning :) my breath can be kickin!! This stuff is the only toothpaste I've tried where I can actually still taste the minty-ness long after I'm finished brushing. Everything else ( incl my old faveCrest with scope) tends to be mint-less right after brushing. This stuff clearly lasts with you, My dad is a dentist and i've tried many toothpastes. For now, this is my top choice. Combined with daily toothpick/flossing, and mouthwash twice a day, this stuff will help fight those bad breath demons we sometimes all get. Enjoy!
