Ingested fluoride is beneficial to dental health. sciblogs.co.nz/open-parachute/2014/04/27/ingested-fluoride-is-beneficial-to-dental-health/ Anti-fluoridation activists work very hard to deny that ingested fluoride has a beneficial role. They take description of the “topical” mechanism that fluoride in saliva plays in inhibiting tooth decay out of context to deny any other role of fluoride. Even then they distort the research to claim fluoride must be applied as toothpaste – it doesn’t. Anything to deny a role for fluoridated water. But research findings do support a beneficial role of ingested fluoride during teeth development – that is on pre-erupted teeth. This was illustrated again in a recent paper reporting incidence of tooth decay in South Korean children. One group lived in an area where there had been no water fluoridation. The other group in an area where fluoridation had stopped 7 years before. Cho et al (2014)* found children of age 11, who drank fluoridated water during their first 4 years (before eruption of their first permanent teeth), had significantly less tooth decay at than children of age 6, who had not had access to community water fluoridation during their first 4 years (see figure below – results for decayed missing and filled teeth (DMFT) expressed as a ratio of results for children in previously fluoridated area divided by results for children in never-fluoridated area).
