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 ...
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 ...
The American Dental Association says adding fluoride to water streams is a "safe, beneficial, and cost-effective" public health measure, citing studies that it cuts cavities in children and adults ...
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.

A 1930s poster from the Work Projects Administration promoting oral hygiene. Tooth decay is the most common global disease. [14] Over 80% of cavities occur inside fissures in teeth where brushing cannot reach food left trapped after eating and saliva and fluoride have no access to neutralize acid and remineralize demineralized teeth, unlike easy-to-clean parts of the tooth, where fewer ...
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.
Other sources include glass-etching or chrome-cleaning agents like ammonium bifluoride or hydrofluoric acid, [12] [13] industrial exposure to fluxes used to promote the flow of a molten metal on a solid surface, volcanic ejecta (for example, in cattle grazing after an 1845–1846 eruption of Hekla and the 1783–1784 flood basalt eruption of ...
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 ...
