Fluoride is a mineral that occurs naturally in many foods and water, as well as an additive (fluoridation) to enhance dental health. Fluoride helps prevent tooth decay by making teeth more resistant to acid attacks from bacteria in the mouth. Fluoride makes it difficult for acids to demineralize teeth, and it helps speed remineralization for repair of tooth enamel. Fluoride is found in toothpaste, some mouthwashes, and at the dentist office as a gel, foam, or varnish. Get more information on fluoride and its importance to dental and oral health.
