Fluoride is commonly added to toothpaste and some water supplies primarily for what health benefit?

Explanation

Fluoride is added to toothpaste and, in some regions, to public water supplies because it helps strengthen tooth enamel and makes it more resistant to the acids produced by bacteria in the mouth, thereby helping to prevent cavities and tooth decay. This practice, known as water fluoridation in areas where it’s used, has been credited with meaningfully reducing rates of tooth decay across populations where it has been implemented. While beneficial in appropriate amounts, excessive fluoride intake during tooth development can occasionally cause a cosmetic condition called dental fluorosis.
