Dental fluorosis is a common [2] disorder, characterized by hypomineralization of tooth enamel caused by ingestion of excessive fluoride during enamel formation. [ 3 ] [ needs update ] It appears as a range of visual changes in enamel [ 4 ] causing degrees of intrinsic tooth discoloration , and, in some cases, physical damage to the teeth.
"Having knowledge of the fluoride level in your community water system and the other amounts of fluoride your child under age 8 is ingesting is the key to preventing dental fluorosis," she says.
Dr. Dean's research on the fluoride-dental caries relationship, published in 1942, included 7,000 children from 21 cities in Colorado, Illinois, Indiana, and Ohio. The study concluded that the optimal amount of fluoride which minimized the risk of severe fluorosis but had positive benefits for tooth decay was 1 mg per day, per adult.
The only generally accepted adverse effect of fluoride at levels used for water fluoridation is dental fluorosis, which can alter the appearance of children's teeth during tooth development; this is mostly mild and usually only an aesthetic concern. Compared to unfluoridated water, fluoridation to 1 mg/L is estimated to cause fluorosis in one ...
Officials lowered their recommendation for drinking water fluoride levels in 2015 to address a tooth condition called fluorosis, that can cause splotches on teeth and was becoming more common in U ...
Dental fluorosis — a condition that occurs when teeth get too much fluoride and appear to be stained — was also used to assess exposure. So were environmental factors, ...
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.
Skeletal fluorosis is a serious condition which causes bone weakness and stiffness and pain in joints. Numerous studies have shown that fluoridated water can help prevent tooth decay and improve ...
