Whih one is essential for preventing dental caries?

Fluoride is essential for preventing dental caries. Fluoride is a mineral that helps to strengthen teeth and make them more resistant to decay. It can be found in toothpaste, mouthwash, and drinking water. Fluoride works by preventing the demineralization of tooth enamel, which is the process by which teeth become damaged and cavities form. Fluoride also helps to remineralize teeth, which is the process by which damaged tooth enamel is repaired.
