Inside our body, organs work together: the heart pumps blood, the lungs take in oxygen, the brain thinks and controls the body, the stomach churns food and the kidneys make urine. Our teeth have jobs too — incisors bite and cut, canines tear and molars grind. A child has 20 milk teeth; a grown-up has 32 permanent teeth.
