What do eating disorders do to the mouth and teeth? Eating disorders can damage your teeth in many ways. It is important to see a dentist for these problems. When a person throws up after eating the acid from the stomach goes through the mouth. That acid can eat away the enamel on teeth and cause cavities. The acid can also cause you to lose teeth. When a person starves, the body does not get the nutrients that it needs. This could lead to osteoporosis. Osteoporosis is a disease that makes the bones in your body weak. The jawbone can get weak and not hold on to the teeth and the teeth may fall out.
