Swallowed teeth are generally not a concern and are not harmful to the body. Because teeth are harmless, small and not very sharp, swallowed teeth will pass through the esophagus, stomach, small intestine and large intestine, and finally with feces out of the body. If you accidentally swallow a tooth, you should eat more easily digestible and fiber-rich foods, such as leeks, celery, fruits, etc., to promote gastrointestinal peristalsis and facilitate the discharge of feces. You should also pay attention to observe whether there are any uncomfortable symptoms in the abdomen, such as stomach pain, and observe whether there are any abnormalities in the stool. However, special attention should be paid to the fact that if a newborn baby finds a tooth falling into the stomach, he or she should promptly go to the hospital for examination to avoid accidental inhalation into the trachea.
