Saliva has no flouride in it. There are natural enzymes in it that help protect your teeth and the rest of your mouth for that matter. A reduction in saliva reduces these, and the Biotene products help replace these enzymes when you use them. In addition to all this being on top of your hygiene and using your high concentration flouride toothpaste or gel/foam in trays is a must.
