How does fluoride help prevent dental caries?
Fluoride is important for the integrity of bones and teeth. Its main functions are: • Building stronger teeth that are more resistant to decay by increasing resistance of teeth to demineralization by acidic foods • Remineralization of the tooth enamel • Interference in formation and function of oral bacteria • Decreasing tooth sensitivity Fluoride can be acquired systemically and topically. Systemically it gets deposited in bones and teeth mainly from community water supply. Therefore, drinking fluoridated water is one of the most effective public health measures in prevention of dental caries. Topical application of fluoride in toothpastes, mouth rinses, and office treatments adds additional benefits to dental caries prevention. Health authorities, such as The American Dental Association recommend brushing teeth two times a day with toothpaste that contains fluoride, if age appropriate. However, small children who can still swallow the toothpaste should NOT use fluoridated toothpaste.
