Rinsing regularly twice daily with TriOral can prevent new, bacterially-generated odor formation for 12 hours after each use. I thought bad breath came from the stomach. Unless the epiglottis opens with a burp or regurgitation, odor cannot arise from the stomach. That is why TriOral can protect for 12 hours. Unfortunately, no one can really smell their own breath.
Some people think they can when they cup their hands over their mouths, breathe, and smell.
However, science has shown that this does not work effectively. The only way to really know is to ask a friend to smell your breath or have a dentist evaluate your breath. You can always use TriOral and feel confident all day. You can use TriOral daily with confidence. I'll never leave home without using it first.
