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 ...
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 ...
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.

Technically, a deep dental cleaning involves two procedures: tooth scaling and root planing, Dr. Elbert Tom, assistant clinical professor and group practice director at the UCLA School of ...
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 ...
Fluoride toothpaste prevents about 25% of cavities in young permanent teeth, and its effectiveness is improved if higher concentrations of fluoride are used, or if the toothbrushing is supervised. Fluoride mouthwash and gel are about as effective as fluoride toothpaste; fluoride varnish prevents about 45% of cavities. [93]
Fluoride is present in small amounts in plants, animals, and some natural water sources. The additional fluoride in toothpaste has beneficial effects on the formation of dental enamel and bones. Sodium fluoride (NaF) is the most common source of fluoride, but stannous fluoride (SnF 2), and sodium monofluorophosphate (Na 2 PO 3 F) are also used ...
[4] [5] Fluoride decreases breakdown of teeth by acids, promotes remineralisation, and decreases the activity of bacteria. [5] Fluoride works primarily through direct contact with teeth. [3] [5] Fluoride came into use to prevent tooth decay in the 1940s. [6] Fluoride is on the World Health Organization's List of Essential Medicines. [7]
