Fluoride is a mineral that occurs naturally in all water sources, including the oceans. Research has shown that fluoride not only reduces cavities in children and adults, but it also helps repair the early stages of tooth decay, even before the decay is visible. Fluoride is the best cavity fighter to help keep the whole family's teeth strong — no matter their ages*
How Does FLUORIDE Strengthen Your Teeth?
When it reaches your teeth, fluoride is absorbed into the enamel. It helps to repair the enamel by replenishing the lost calcium and phosphorous to keep your teeth hard. This process is caused remineralization. When fluoride is present during remineralization, the minerals deposited into the tooth enamel help strengthen your teeth and prevent dissolution during the next demineralization phase. Thus, fluoride helps stop the decay process and prevent tooth decay.
Dental professionals recommend brushing with fluoride toothpaste to strengthen tooth enamel and prevent decay. This is especially important for children during their "cavity-prone" years. As an adult, however, there are times when you are at higher risk for tooth decay, and a fluoride rinse may be an appropriate addition to your oral hygiene routine.
