Fluoride is a common component in toothpaste. It is a mineral that helps strengthen tooth enamel and prevent dental cavities. The addition of fluoride to oral care products such as toothpaste and mouthwashes has been highly effective in reducing the incidence of tooth decay. By remineralizing enamel and making teeth more resistant to acid attacks from bacteria, fluoride plays a crucial role in maintaining oral hygiene. Although natural sources of fluoride include water and certain foods, its application in dental products has significantly contributed to better dental health worldwide.
