Your mouth is full of tiny bacteria. These bacteria eat the sugar from your food and make acid. The acid attacks your enamel, the hard layer on the outside of your teeth. Over time, this creates plaque, a sticky film that sits on your teeth. If plaque stays too long, it can make a cavity, a small hole in your tooth. Good hygiene stops this from happening. Brush your teeth twice a day to wash away bacteria and plaque. Healthy teeth help you eat, speak, and smile!
