I am on oxygen.
My breath is horrid because of it.
For years I have been sucking down water because my mouth was dry and eating breath mints and candies and brushing my teeth to death trying to improve my breath.
It turns out that a product called Biotene works wonders! It is for people who have dry mouths. I was hesitant to try it because of the price and I didn't realize that my breath was so bad because of my dry mouth caused by my oxygen.
I recently tried the stuff. It is worth every penny and my breath is actually bearable now! To me and to others!
Long Live Biotene!
