Periogen stands alone as simply the best, most researched, and most effective oral health rinse in the world having just won the prestigious 2018 Edison Award under Health and Wellness as well as an award for our research results at the August 2018 Hong Kong Dental Expo. We are now award winning on three continents! No other oral care product can do what Periogen does and that is to safely and progressively prevent & remove disease harboring dental tartar buildup with each application. Your dentist will tell you that dental tartar is made of plaque that has hardened into tartar and is the cause of nearly all gum issues and that is why your dental professional wants to remove it through scraping. Splashing harsh acidic mouthwashes in your mouth does nothing to remove tartar buildup and can in fact make things worse by causing plaque to calcify & harden into more tartar. When you use Periogen, you are both preventing & progressively removing dental tartar. Periogen studies confirm a 45% reduction in plaque and tartar buildup over 4 months when compared to brushing alone. Our formula is gentle, safe and has a mild flavor. Periogen is not acidic in any way with a healthy 7.5 pH and will not harm enamel or dental appliances. Periogen is great for kids with braces and adults with implants or bridges. We are proud of our our numerous 5-star clinical studies and encourage you to read our Amazon reviews and especially the customer comments associated with those reviews. Be sure to check out our instructional video below and then try Periogen for 90 days. For some of us, Periogen may take a little time, but the results are worth the wait. Then join the thousands of people whose dentist has said “your mouth looks great, what have you been doing differently?” For best results brush with Periogen Toothpaste prior to rinsing. Made in the USA.
