Fluoride is one of the minerals that make up the structure of your tooth enamel. Getting fluoride treatments helps with the remineralization process that strengthens tooth enamel while helping to prevent tooth decay. The fluoride varnish treatment provided in our dental office works in a different way than fluoride in your toothpaste or mouthwash at home, because it is much stronger and actually kills the bacteria that can cause cavities, while helping to strengthen your teeth!
