Stand back – it's plaque! Plaque is a sticky, slimy substance made up mostly of the germs that cause tooth decay. That's why it's important to brush your teeth at least twice every day and floss daily. If too much plaque builds up on and between your teeth, you'll get cavities or – even worse – gum disease!
