Mouthwash does not prevent tooth decay. A fluoride rinse however is a good addition to a thorough brushing and flossing routine. Plaque reacts with sugars and starches to form an acid, which breaks down the minerals in the enamel of the teeth, thereby causing a cavity. Your saliva contains minerals, which can replace the minerals, which have been destroyed by the acids. Fluoride acts together with these minerals to help in this re-mineralization process. Mouthwashes with fluorides in them will work together with your saliva to help your teeth ward off cavities. Adding a fluoride rinse to a to a thorough brushing routine along with the fluoride treatments your dentist can provide will help to keep your teeth healthy.
