Flouride

For strong teeth without cavities, dentists advise brushing with a fluoridated toothpaste. That’s because fluoride is extremely effective at strengthening tooth enamel. When bacteria feed on sugars and starches in food, they produce an acidic waste that dissolves the mineral crystals in your tooth enamel. Fluoride in toothpaste replaces the lost minerals with an even stronger crystalline structure.

The types of fluoride commonly used in toothpaste are stannous fluoride and sodium fluoride. Stannous fluoride toothpaste was the first fluoride toothpaste on the market, but nowadays many toothpaste products contain sodium fluoride.
