Final answer:
Fluoride treatments usually occur at the end of a dental appointment, and fluoride is important for preventing tooth decay by strengthening tooth enamel and reducing the solubility of teeth to acid attacks.
Step-by-step explanation:
Fluoride treatments are typically performed at the end of a dental appointment, after the teeth have been cleaned and any other treatments have been conducted. The use of fluoride is an essential part of dental health, as it contributes to the prevention of tooth decay. Community water fluoridation is known as a cost-effective way to deliver fluoride to the community, reducing tooth decay by 25% in both children and adults. The mineral fluoride naturally occurs on Earth and is released into the soil, water, and air, enhancing the resistance of tooth enamel to acidic attacks through the formation of fluorapatite, which is less soluble.
