Which chemical compound is added to toothpaste to ensure strong teeth?

Fluoride is called a micro-nutrient, which refers to a nutrient required by the human body, although in small quantities (e.g., vitamins and minerals). It is among the minerals that are important nutrients. In addition, fluoride does not exist by itself but is contained in many kinds of food around us. It is always combined with other substances, such as sodium fluoride combined with sodium or calcium fluoride combined with calcium. Use toothpaste containing fluorine as an active ingredient, so as to prevent caries through its various effects. It is said that the prevention rate for caries when fluoride toothpaste is used for approximately 2 years is about 20 to 30%. The prevention rate will increase as you continue to use it. Fluoride is the main cavity-fighting ingredient in toothpaste, which helps strengthen enamel and prevent tooth decay.
