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 toothpaste, with concentrations of 1000 ppm and above, reduces the risk of dental caries in school-aged children and adolescents. [10] As primary teeth are being developed, the ingestion of fluoride causes the teeth to form stronger and more resistant to cavities, although this increases the risk of dental fluorosis.
Dental fluorosis is the most common indication where it ranges in severity from mild to severe, microabrasion should be considered the first option in treating mild and moderate cases of fluorosis.
In most cases, fluorosis is cosmetic and isn't harmful to your health. According to Henderson, it's more common when children use multiple sources of fluoride over a long period of time.
Mild fluorosis: mostly on the upper right central incisor Severe fluorosis: mottled enamel of an individual from a region with high levels of naturally occurring fluoride Fluorosis may occur when there is chronic and excessive exposure to fluoride during the years of tooth development.
Fluoride varnish is a highly concentrated form of fluoride that is applied to the tooth's surface by a dentist, dental hygienist or other dental professional, as a type of topical fluoride therapy. [1] It is not a permanent varnish but due to its adherent nature it is able to stay in contact with the tooth surface for several hours.
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 ...
The authors also noted that adding fluoride to drinking water may increase the number of people with dental fluorosis, a mostly cosmetic condition that can leave the teeth with white flecks, spots ...
