The American Dental Hygienist Association says that nearly 40 million Americans commonly suffer from bad breath, also known as oral malodor or halitosis. It is generally caused by strong foods such as onions or garlic, poor oral health habits, or medical problems such as stomach disorders, an excessive postnasal drip, or bacteria in the mouth. Unlike many products that mask bad breath with sweeteners and chemicals, EssentialOxygenTM Brushing Rinse does not add the sweeteners, artificial sweeteners, and flavorings that actually attract bacteria, and therefore genuinely cleans and freshens the mouth for many hours at a time.
