I've heard that things expand and contract when they come in contact with hot or cold. I've also heard about a myth in which a person drinks a hot cup of coffee and then eats and ice cream cone, and because of the extreme change in temperature, the teeth explode.

heck no. who told you that, yourself.

maybe if you had hollow teeth.

but to explode you would have to do it the other way around.

maybe not like, explode, but shatter.

sometimes if you wash out a hot coffee pot with cold water they shatter.

what if the teeth are false?

The might shatter but not explode. if you take a glass from the dish washerand put icein it it will shatter not explode.

WOW STOP BELEIVING WHAT FOAMY THE SQUIRL SAYS OR YOUR GOING TO BE TAKEN OVER BY SQUIRLS THEY ARE YOUR LORD AND MASTER
