Myth 3: Mouthwash cures bad breath
Mouthwash may temporarily curtail stinky breath, but it’s not a permanent fix. Smelly compounds from your garlicky lunch, for example, are actually coming from your lungs as you exhale, so freshening your mouth won’t help for long. Your saliva can work against you too. Saliva dilutes mouthwash. In some cases, the proteins in saliva can reduce the effectiveness of mouthwash ingredients.
