Final answer:
The body stores the majority of its fluoride in teeth and bones, where it helps to form fluorapatite, which strengthens these structures and protects them from decay.
Step-by-step explanation:
The majority of our body's fluoride is stored in the teeth and bones. This is due to the role of fluoride in the formation of fluorapatite, which occurs when fluoride ions react with hydroxylapatite in our bones and teeth. This reaction forms a more acid-resistant and less soluble compound, thereby protecting these structures from decay.
In addition, community water fluoridation is recognized as an effective method for preventing tooth decay. The presence of fluoride, along with calcium, is crucial for maintaining the strength and health of teeth and bones.
