Caries-inhibiting effects of fluoride were first noticed 1902, when fluoride in high concentrations was found to stain teeth and prevent tooth decay. Fluoride salts, particularly sodium fluoride (NaF), are used in the treatment and prevention of osteoporosis . [ 13 ]
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]
Research has found that adding fluoride to water reduces the amount of tooth decay in young kids by 35%. Can fluoride be harmful? Fluoride is beneficial, say experts.
Fluoride is a naturally occurring mineral that’s “crucial for our dental health because it helps to prevent tooth decay” and reduces your risk for cavities, says Cheryline Pezzullo, D.D.S ...
