In addition to being able to prevent cavities, fluoride rinsing can actually help to remineralize teeth.

The earliest stage of a cavity is a demineralized area or “white spot”. On an x-ray, these may appear as very small areas that are still limited to the outer enamel surface of the teeth.

In such cases, especially on permanent teeth, together with flossing, these fluoride rinses can overcome the demineralizing process and help to strengthen the enamel.

Using fluoride rinses can make these small cavities disappear.

Fluoride rinses should not be used by individuals that can’t rinse without swallowing.
