Other fluoride therapies are also effective in preventing tooth decay; [33] they include fluoride toothpaste, mouthwash, gel, and varnish, [95] and fluoridation of salt and milk. [22] Dental sealants are effective as well, [ 33 ] with estimates of prevented cavities ranging from 33% to 86%, depending on age of sealant and type of study.
Fluoride helps prevent decay of a tooth by binding to the hydroxyapatite crystals in enamel. [122] Streptococcus mutans is the leading cause of tooth decay. Low concentration fluoride ions act as bacteriostatic therapeutic agent and high concentration fluoride ions are bactericidal. [123]
This level is equivalent to just 70 cents out of every $1 million in water supply, providing an affordable and effective solution for tooth decay prevention, according to the press release.
The research had two goals: (1) to warn communities with a high concentration of fluoride of the danger, initiating a reduction of the fluoride levels in order to reduce incidence rates of fluorosis, and (2) to encourage communities with a low concentration of fluoride in drinking water to add fluoride in order to help prevent tooth decay. By ...
Since then, research has found that adding fluoride to water lowers the amount of tooth decay in young kids by 35%. Because of this, the CDC calls fluoridation “one of 10 great public health ...
The fluoride ions reduce the rate of tooth enamel demineralization and increase the rate of remineralization of teeth at the early stages of cavities. Fluoride exerts these effects by the demineralization and remineralization cycle. [23] The remineralization cycle, critical to decay prevention, occurs when fluoride is present in the oral cavity.
