Periogen improves oral health like no other product in the world by safely and progressively removing and preventing dental tartar and plaque buildup with each application. Outside of a dental office Periogen is the only product that can remove the hard porous dental tartar material that gives bacteria a place to thrive and grow. Typical mouth rinses, herbals, and oils attempt to kill bacteria, but the effect is only temporary as the bacteria come right back to live in the tartar buildup. The solution is simple; remove dental tartar buildup and end red, sore or bleeding gums, gingivitis and gum disease. Periogen studies confirm a 45% reduction in plaque and tartar buildup when compared to brushing alone. Our formula is non acidic with a healthy 7.5 pH; contains no alcohol, bleach, or triclosan; and will not harm enamel or dental appliances. Don't pay for water in your oral rinse! One 3 ounce bottle of Periogen powdered concentrate makes 3 gallons of rinse (45 day supply). While we are proud of our Amazon Customer reviews, we are also proud of our Periogen "5-Star" clinical results that are turning the heads of dental professionals and researchers the world over. So far, five clinical studies have been completed on Periogen by Dental Universities around the world. The latest study undertaken at Italy's premiere dental university compared Periogen's plaque reduction ability against the current dental "Gold Standard -chlorhexidine (CHX)" The results indicate that Periogen is equal to chlorhexidine in plaque reduction without the negative side effects of chlorhexidine! All clinical results are available for review on the Periogen homepage. You can stay up with future research and gain insightful oral health information by subscribing to our newsletter.
