Hello, I'm Genericusername57. I wanted to let you know that one or more of your recent contributions to Biotene have been undone because they appeared to be promotional. Advertising and using Wikipedia as a "soapbox" are against Wikipedia policy and not permitted; Wikipedia articles should be written objectively, using independent sources, and from a neutral perspective. Take a look at the welcome page to learn more about Wikipedia. Thank you. gnu 57 15:32, 3 March 2019 (UTC)
