Fluoride is a mineral that helps prevent caries & repair teeth in early, microscopic stages of decay. Those at risk of caries can take advantage of fluoride treatment by a dentist by gel, foam or varnish with a cotton swab or brush or by a rinse in a tray. Patients are asked not to rinse, eat or drink for 30 minutes for teeth to absorb the fluoride & repair microscopic caries. We may also recommend complementary measures such as OTC or prescription mouthwashes or anti-bacterial gels.
