Fluoride is the mineral commonly known for its use in toothpaste. It is added to many dental care products because of its effectiveness in preventing tooth decay and enhancing dental health. Fluoride works by making teeth more resistant to acid attacks from bacteria in the mouth and can even reverse early signs of tooth decay. It is crucial to maintain a proper balance of fluoride, as excessive exposure can lead to dental fluorosis. The incorporation of fluoride in toothpaste has significantly contributed to improved oral health standards in many populations around the world.
