Imagine your tooth enamel is like a suit of armor. Every time you eat a sugary snack or sip a soda, little acid attacks try to chip away at that armor. Over time, those chips turn into cavities—tiny holes that make your teeth sad. Fluoride swoops in like a repair crew, fixing those weak spots before they become big problems.
It does this through a process called remineralization. Basically, fluoride helps your teeth soak up minerals like calcium and phosphate from your saliva, making the enamel stronger and more resistant to decay. It’s like giving your teeth a daily vitamin boost, but instead of a pill, you’re just turning on the kitchen faucet.
