What is the role of fluoride in dental care?

  1. Bleaches teeth

  2. Helps to remineralize enamel and prevent tooth decay

  3. Removes plaque from teeth

  4. Whiten gums

The correct answer is: Helps to remineralize enamel and prevent tooth decay

Fluoride plays a crucial role in dental care primarily because it helps to remineralize enamel and prevent tooth decay. When fluoride is present in the oral environment, it can be incorporated into the structure of tooth enamel. This incorporation strengthens the enamel and makes it more resistant to demineralization caused by acids produced by bacteria that feed on sugars in the mouth. Additionally, fluoride can enhance the efficiency of the remineralization process by attracting other minerals, such as calcium and phosphate, to the areas of enamel that have begun to demineralize. By promoting this restorative process, fluoride effectively aids in the prevention of cavities and supports overall oral health.
