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.
Causal factors may occur locally, affecting only a single tooth, or they may act systemically, affecting all teeth in which enamel is being formed. Local trauma or abscess formation can adversely affect the ameloblasts overlying a developing crown, resulting in enamel hypocalcification or hypoplasia. Affected teeth may have areas of coronal ...
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 is a mainstay of dental care, whether it's delivered in a treatment at your dentist's office or in your toothpaste. But fluoride has become the focus of several conspiracy theories over ...
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.
Turner's hypoplasia or Turner's tooth is a presentation of enamel hypoplasia that normally affects only a single tooth. Its causes can be the same as other forms of enamel hypoplasia, but it is most commonly associated with trauma to a primary maxillary central incisor and the subsequent developmental disturbance of the underlying permanent ...
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. [10] [11] [12] Water and milk fluoridation are two forms of systemic fluoride therapy that are effective at preventing dental cavities. [13]
Although fluoridation can cause dental fluorosis, which can alter the appearance of developing teeth or enamel fluorosis, [3] the differences are mild and usually not an aesthetic or public health concern. [12] Fluoride's effects depend on the total daily intake of fluoride from all sources.
