What's inside teeth?

Our teeth are incredible chomping machines. Their strong outer layer helps us crunch carrots, nibble potato chips and chew bubblegum! But what’s inside of them? We asked dentist Dr. Jean Star to help us find the answer. Got a question that’s eating you up inside? Send it to us at BrainsOn.org/contact, and we’ll chew it over!
