Periogen is for individuals who are seeking an alternative to expensive and painful removal of oral tartar by dental professionals, thus avoiding thousands of dollars in expense and discomfort over a lifetime. Periogen is the world's first and only alternative to professional dental cleanings. Periogen progressively dissolves dental tartar with each application. According to the dental industry, tartar, the hard mineralized substance that forms on teeth, can only be removed through manual scraping. With Periogen, that is no longer true. Tartar, both above and below the gum-line, is comprised primarily of calcium phosphate salt. Periogen works by releasing the electrostatic bonds that enable tartar to stick to teeth. Periogen gently and progressively eliminates tartar from wherever it reaches. The time required to remove your tartar varies depending upon age of tartar and your commitment to the Periogen routine. Periogen begins removing tartar from the first application, with complete dissolution in as little as 6 to 8 weeks. Once tartar is gone, occasional Periogen use will keep tartar from re-forming. Aside from Periogen or the dentists chair, there is simply no other way to remove tartar once formed. The facts are that the former National Institute of Health Dental Director Dr. Paul Keyes was impressed enough with our product to offer his unpaid endorsement in 2008. He used Periogen and came to the conclusion that "Periogen may be the most revolutionary dental product to hit the market in 20 years". You can read his quote on our website. The Periogen Company has never paid for an endorsement of the product as the results speaks for itself. You can reach out to us or one of our ever growing numbers of supporting dentists by visiting the Periogen website and using the "contact us" link.
