Fluoride & Tooth Decay: Topical vs. Systemic Effect
When water fluoridation first began in the 1940s, dentists believed that fluoride’s main benefit to teeth came from being swallowed during the tooth-forming years. Today, the overwhelming consensus by dental researchers is that fluoride’s primary effect is topical, not systemic, and that this topical effect occurs after the teeth have erupted into the mouth (i.e., post-eruptive), not before. There is no need, therefore, to swallow fluoride, especially during infancy and early childhood.
Topical vs. Systemic Effects
When water fluoridation first began in the 1940s, dentists believed that fluoride’s main benefit to teeth came from being swallowed during childhood. When swallowed before the teeth erupted, dentists claimed fluoride would build up in the internal matrix of the teeth and make them more resistant to cavities for the rest of the child’s life. As […]
Fluoride: “No Convincing Effect” on Permanent Teeth
A team of European researchers have put fluoride to the test – and fluoride (devoid of anecdotal ‘evidence’ from enthusiastic dentists) appears to have flunked.
Fluoride Is Not an Essential Nutrient
In the 1950s, dentists believed that fluoride was a “nutrient.” A nutrient is a vitamin or mineral that is necessary for good health. Dentists believed that fluoride ingestion during childhood was necessary for strong, healthy teeth. A “fluoride deficiency” was thus believed to cause cavities, just like a deficiency of calcium can cause osteoporosis, or a deficiency […]
