What is really happening when you brush your teeth?
You do it twice a day, every day. But what's actually happening in there when you brush your teeth? It's not just scrubbing — it's a tiny battlefield, a chemistry experiment, and a construction project all happening at once in your mouth.
First, the enemy: bacteria. Your mouth is home to billions of them, living in a sticky film called plaque that clings to your teeth like invisible glue. These bacteria eat the sugars from your food and poop out acid. Yes, acid. That acid is what eats tiny holes in your enamel — the super-hard shell protecting each tooth.
