Fluoride is a naturally occurring mineral that has been shown to both prevent tooth decay & even reverse it in the early stages. Fluoride acts by strengthening your enamel, which is the hard shiny outer layer of your teeth that protects the softer, more vulnerable dentin beneath. Fluoride can re-mineralize tiny micro-cavities before they have the chance to grow into larger cavities & cause problems.
We recommend fluoride as a preventive treatment for children. Fluoride treatments are usually done at six-month cleaning appointments & usually take the form of a rinse or varnish that is applied directly to the teeth. We may also recommend fluoride treatments for adults at a high risk of tooth decay.
And of course, we always recommend that you use a toothpaste that contains fluoride.
