i have bad breath and I have used therabreath product with success. I used to have a quite severe bad breath that I can smell my own bad breath easily.
So to the poster below: if you have a quite severe bad breath, you can confirm this by yourself and the reaction from people.
anyway why don't you give it a try. Therabreath has worked for me for years..until recently when my breath got worse although I still managed to keep my breath relatively mild and tolerable with Therabreath. Good luck
PS. therabreath didn't immediately eliminate bad breath for me in a day. It took around 2-3 weeks of constant tongue scraping with the toothpaste many times at a time 3 times day or as necessary before I noticed significant improvement in my breath.
