I have question for chemistry
why is it important to use a toothpaste containing fluoride?
Tooth enamel consists of the "insoluble" material hydroxyagpatite. Explain briefly, using chemical principles, why acidic food cause tooth decay if you don't brush your teeth.

The purpose of oral hygiene is to prevent the build-up of plaque, the sticky film of bacteria and food that forms on the teeth. Plaque adheres to the crevices and fissures of the teeth and generates acids that, when not removed on a regular basis, slowly eat away, or decay, the protective enamel surface of the teeth, causing holes (cavities) to form. Plaque also irritates .
Fluoride kills the bacteria found in plaque and strengthens enamel. Added in toothpastes, mouth rinses and topical gels, fluoride is also found naturally in drinking water.參考資料： yen, dictionary
