Which mineral is primarily associated with dental health?

Explanation:
Fluoride is the mineral most closely linked to dental health because it strengthens enamel and helps prevent decay. It becomes part of the enamel as fluorapatite, making teeth more resistant to acid and enabling remineralization of early lesions. This dual action—hardening enamel and promoting repair—explains why fluoride in toothpaste, varnish, and water fluoridation reduces cavities. Calcium supports tooth structure, but fluoride has the specific protective effect against decay. Iodine is important for thyroid function and has no direct role in teeth, and magnesium supports general bone health rather than enamel protection.
