Question 67. Describe the role of fluoride in dental care.
Answer: Hydroxyapatite crystals lead to the hardness of tooth enamel. But the hydroxyapatite crystals are readily dissolved by the action of acids over a period of time.

Fluoride radical is highly reactive, so it exchanges with hydroxyl radical and leads to the formation of fluorapatite.

Fluorapatite is more compact, and harder, and is a less acid-labile substance than hydroxyapatite. This leads to teeth becoming more caries-resistant.
