Is swallowing toothpaste harmful to children?
Occasionally swallowing small amounts of toothpaste usually poses no problem, but it depends on the amount of fluoride your child gets. Ask your dentist whether your child is getting enough – or too much – fluoride. Too much can cause nausea and fluorosis, a discoloration of the teeth. Be aware that trace amounts of fluoride can be found in fruit juices and sodas as well as in drinking water.
