Dr Dental, On Fluoride
Fluoride penetrates into teeth. Fluoride helps to strengthens teeth by replacing minerals that acid has removed. The benefits of fluoride to teeth were first discovered in the 1930s. Dentists started to notice that people who drank water that naturally contained fluoride had less tooth decay. In 1945, communities started to add fluoride to water supplies. Adding fluoride to water systems has been the most successful cavity prevention method to date. In the early 1960s, fluoride also began to be added to toothpaste. This also had a major impact on cavity prevention. Now almost all toothpastes contain fluoride. Everyone should brush with a fluoride toothpaste every day.
