Which is a main benefit of fluoride in dental care?

It strengthens tooth enamel
It promotes gum health
It whitens teeth
It reduces bad breath

The correct answer is: It strengthens tooth enamel

Fluoride is a key component in dental care primarily because it strengthens tooth enamel, which is the hard, outer surface of teeth. When fluoride is applied or ingested, it is incorporated into the tooth structure, making it more resistant to acid attacks from bacteria in the mouth. This process enhances the remineralization of enamel, helping to repair early signs of tooth decay. The strengthened enamel can better withstand decay caused by sugary foods and beverages, thereby playing a crucial role in preventing cavities. While fluoride has some indirect benefits related to oral health, such as promoting overall tooth longevity, its most significant and well-documented role is in strengthening enamel. Other options, such as promoting gum health, whitening teeth, and reducing bad breath, do not directly relate to fluoride's primary benefit in dentistry.
