Causes and tips: There are causes for dry mouth like medications, systemic diseases and radiation treatment to the head. Usually the white coating is plaque and can be removed by brushing or more effectively with a tongue scrapper. The dry mouth is sometimes treated with medication but usually treated with a saliva substitute... Many otc products.. I like spry because it contains xylotol which kills bacteria.
