Dental fluorosis is caused by a higher than normal amount of fluoride ingestion whilst teeth are forming. Primary dentine fluorosis and enamel fluorosis can only happen during tooth formation, so fluoride exposure occurs in childhood. Enamel fluorosis has a white opaque appearance which is due to the surface of the enamel being hypomineralised ...
Topical fluorides are fluoride-containing drugs indicated in prevention and treatment of dental caries, particularly in children's primary dentitions. [1] The dental-protecting property of topical fluoride can be attributed to multiple mechanisms of action, including the promotion of remineralization of decalcified enamel, the inhibition of the cariogenic microbial metabolism in dental plaque ...
Fluoride helps to strengthen your teeth, Rebecca Henderson, associate professor in The Ohio State University College of Dentistry, tells Yahoo Life. "Teeth, like bones in our body, are composed of ...
Fluoride varnish is widely used in the United Kingdom, following guidelines from multiple sources backing its efficacy. Public Health England, a UK government organisation sponsored by the Department of Health, released guidance in 2014 recommending fluoride varnish application at least twice yearly for children and young adults.

The benefits of fluoride for your teeth have been well-established for decades, but “the controversy about fluoride goes back to the very beginning,” says Howard Pollick, B.D.S., a ...
The cavity-prevention effect of fluoride is partly due to these surface effects, which occur during and after tooth eruption. [17] Fluoride interferes with the process of tooth decay as fluoride intake during the period of enamel development for up to 7 years of age; the fluoride alters the structure of the developing enamel making it more ...
Although fluoride is safe for dental health at low concentrations, [1] sustained consumption of large amounts of soluble fluoride salts is dangerous. Referring to a common salt of fluoride, sodium fluoride (NaF), the lethal dose for most adult humans is estimated at 5 to 10 g (which is equivalent to 32 to 64 mg elemental fluoride/kg body weight).
This came after a doctor’s research on fluoride and fluorosis—the discoloration of tooth enamel from an excess of fluoride—and his hunch that safe levels might serve to prevent tooth decay.
