Uh-oh, you feel a dull pain in an a upper molar on the right side of your mouth. Shouldn't have eaten all those marshmallows. It's better to eat fruits and vegetables. But who can resist for marchmallows?! So, dont worry. Continue eating marshmellows. If you loose all you teeth, you can replace them with the artificial ones. Or get metal teeth like the Bond villian Jaws.
