We all liked chewing gum at childhood and tried to swallow it a lot of time but we didn't know its danger.
There is no problem if your child swallows one gum because it's digested in less than one hour and removed in the large intestine. But if he swallows more of chewing gum, he may feel a hard abdominal pain with nausea caused by a blockage in the intestine.
Without forgetting tooth decay because it contains a high percentage of artificial useless sugar, flavors and colorings responsible for sweet taste, and also stimulates activities and reproduction of bacteria inside the mouth.
