But Why is a show led by kids. They ask the questions and we find the answers. It’s a big interesting world out there. On But Why, we tackle topics large and small, about nature, words, even the end of the world. Know a kid with a question? Record it with a smartphone. Be sure to include your kid's first name, age, and town and send the recording to questions@butwhykids.org!
Why Do Baby Teeth Fall Out?
We're talking about teeth with a friendly dentist! How do teeth become loose? Why do our baby teeth fall out? Why do people only have two sets of teeth? Why don't babies have teeth when they're born? Why are teeth white? Why do we have gums in our mouth? How does toothpaste clean your teeth? How does sugar make cavities? We get answers from Theron Main, a pediatric dentist at Timberlane Dental Group in South Burlington, Vermont.
