Fluoride is the most vital ingredient in any toothpaste. It is a mineral that is found naturally and prevents tooth decay and cavity creation. Fluoride protects your teeth from acid-forming sugars and foods that bacteria feeds on. This amazing mineral firstly makes your tooth’s enamel stronger and secondly, it can reverse potential acid damage by hardening those areas of your tooth sunstone that may have already started to decay. Therefore, it doesn’t matter which type of toothpaste you are using, as long as it contains fluoride, it will be effective.
