Ingesting fluoride doesn’t protect your teeth

For any benefit to be derived from fluoride, a topical application – NOT ingestion – is necessary. Fluoride’s supposed benefits for cavity prevention occur when applied directly to teeth, and not systemic. There is no need to swallow fluoride, whether it be in the form of toothpaste, fluoridated water or mouth washes, etc. Additionally, all the recent large-scale studies are proving that there is no significant or consistent difference in the cavity rates between fluoridated versus non-fluoridated regions. Why would anyone swallow something toxic if it is meant to provide a benefit when applied topically?
