fluoride
Fluoride is a naturally occurring mineral found in soil, water, and various foods. It is commonly added to toothpaste and public drinking water because of its ability to prevent tooth decay. Fluoride works by strengthening tooth enamel, making it more resistant to cavities caused by acid from bacteria in the mouth. While it is beneficial for dental health, excessive fluoride exposure can lead to dental fluorosis, which affects teeth appearance. Overall, when used appropriately, fluoride is an effective measure in promoting oral hygiene and reducing the incidence of cavities, especially in children.
