Riverwell ad: Your mouthwash is making your breath worse.

I sold mouthwash for 19 years. Three weeks ago my wife asked what I'd changed. It wasn't the mouthwash. I threw it out. Rinse, gum, mints, scrapers: about $1,000 a year to cover it for thirty minutes at a time. This is $32.90 a month, about $400 a year, and it shuts the gas off. Your tongue doesn't smell because it's dirty. It smells because it's producing gas. Bacteria between your back papillae break down proteins and release sulfur compounds — continuously. Brushing cleans your teeth. The gas keeps coming from behind them. Mint covers it. Alcohol mouthwash dries the zone and makes it worse. Zinc binds to the sulfur and neutralizes it chemically. That's not masking. That's shutting it off. Works by tonight.
