The severity of the condition is dependent on the dose, duration, and age of the individual during the exposure. [1] The "very mild" (and most common) form of fluorosis, is characterized by small, opaque, "paper white" areas scattered irregularly over the tooth, covering less than 25% of the tooth surface.
Fluorosis may occur when there is chronic and excessive exposure to fluoride during the years of tooth development. [ 3 ] [ 10 ] Fluoride is a naturally occurring mineral in water, although some regions have higher levels than others, and in some areas fluoride is added to water supplies in low levels to help prevent tooth decay.
Fluorosis leads to mottled enamel and occurs from overexposure to fluoride. [25] Tetracycline staining leads to brown bands on the areas of developing enamel. Children up to age 8 can develop mottled enamel from taking tetracycline. As a result, tetracycline is contraindicated in pregnant women.
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 ...
Enamel hypocalcification is a defect of tooth enamel in which normal amounts of enamel are produced but are hypomineralized. [ 1 ] [ 2 ] In this defect the enamel is softer than normal. Some areas in enamel are hypocalcified: enamel spindles, enamel tufts, and enamel lamellae.
The agency says risks of water fluoridation are limited to dental fluorosis, which can alter dental enamel and cause white flecks, spots, lines or brown stains on the teeth when too much fluoride ...
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 ...
In the US mild or very mild dental fluorosis has been reported in 20% of the population, moderate fluorosis in 2% and severe fluorosis in less than 1%. [ 63 ] The critical period of exposure is between ages one and four years, with the risk ending around age eight.
