Final answer:
A lower pH on the teeth causes demineralization and tooth decay. Fluoride helps rebuild and strengthen the enamel, reducing the risk of cavities. Regular dental care and sugar reduction are also important for preventing tooth damage.
Step-by-step explanation:
A lower pH on the teeth causes demineralization and tooth decay. Dental caries, or cavities, develop when bacteria in the mouth feed on sugars and release acids that degrade the calcium crystals of the enamel. This acid erosion weakens the tooth's surface, increasing the risk of cavities.
Fluoride has been proven to protect teeth from decay by rebuilding and strengthening the enamel. It also reduces the production of acids by bacteria and enhances the uptake of essential minerals in tooth enamel.
Regular dental cleanings, reducing sugar consumption, and using sugarless candies or gum with sugar alcohols can also help prevent tooth damage and decay.
