Final answer:
Fluoridated toothpaste is a source of topical fluorides, which have beneficial effects on dental enamel and bones. It protects tooth enamel against acidity caused by oral microbes and reduces the production of acids that contribute to tooth decay.
Step-by-step explanation:
Fluoridated toothpaste is a source of topical fluorides. Fluoride in toothpaste has beneficial effects on the formation of dental enamel and bones, preventing cavities. It becomes incorporated into the hydroxyapatite of tooth enamel, making it more resistant to corrosive acids produced by oral microbes. Additionally, fluoride accumulates in plaque-forming bacteria, interfering with their metabolism and reducing their production of acids that contribute to tooth decay.
