ProFresh attacks bad breath at its source - your tongue! Scientific studies have shown that bad breath or halitosis is caused by bacteria that accumulate on the back of your tongue. ProFresh has been scientifically developed and proven clinically effective in removing bad breath / halitosis bacteria, eliminating the odors they produce and leaving you with fresh, clean breath. The ProFresh Breath Care System was developed by Dr. Jon L. Richter, directly from his successful clinical treatment program. ProFresh is the only patented oral rinse that contains active Chlorine Dioxide which removes odor causing bacteria. The U.S. Patent awarded to Dr. Richter for ProFresh excludes any other mouthwash from containing a significant amount of chlorine dioxide. Once odor is controlled with ProFresh you follow a simple two minute maintenance program, twice a day, to maintain fresh breath 24 hours a day. The ProFresh daily regimen also reduces the amount of "free floating" bacteria in the mouth and consequently the amount of dental plaque, a cause of dental decay and periodontal disease. ProFresh International Corp., is the maker of the ProFresh Breath Care System.
