Dental fluorosis is a common [2] disorder, characterized by hypomineralization of tooth enamel caused by ingestion of excessive fluoride during enamel formation. [3] 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.
Fluoridation does not affect the appearance, taste or smell of drinking water. [ 1 ] Water fluoridation is the addition of fluoride to a public water supply to reduce tooth decay. Fluoridated water contains fluoride at a level that is effective for preventing cavities; this can occur naturally or by adding fluoride. [ 2 ]
Fluorosis is a condition resulting from the overexposure to fluoride, especially between the ages of 6 months and 5 years, and appears as mottled enamel. [3] Consequently, the teeth look unsightly, although the incidence of dental decay in those teeth is very small.
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.
The NHMRC an Australian Government statutory body, released the public statement of efficacy and safety of fluoridation 2007 to set the recommended water fluoridation to the target range of 0.6 to 1.1 mg/L, depending on climate, to balance reduction of dental caries (tooth decay) and occurrence of dental fluorosis (mottling of teeth). Moreover ...
Dentistry. Tooth discoloration is abnormal tooth color, hue or translucency. [1] External discoloration is accumulation of stains on the tooth surface. Internal discoloration is due to absorption of pigment particles into tooth structure. [2][3] Sometimes there are several different co-existent factors responsible for discoloration.
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.
Tooth whitening. Tooth whitening or tooth bleaching is the process of lightening the color of human teeth. [ 1 ] Whitening is often desirable when teeth become yellowed over time for a number of reasons, and can be achieved by changing the intrinsic or extrinsic color of the tooth enamel. [ 2 ] The chemical degradation of the chromogens within ...
