Why do we get cavities?

Your teeth are like a squad of superheroes inside your mouth. They help you crunch on carrot sticks, nibble popcorn and chew bubblegum. You’ve probably heard it’s important to brush your teeth to prevent cavities. But what is a cavity? And how do dentists fix them?


Join Molly and cohost Aya on a terrifically toothy adventure, as they explore what causes these pesky little holes in our teeth. They’ll meet a group of rowdy, party-loving bacteria and find out how sometimes, troublemaker bacteria in our mouths can cause cavities. Plus, dentist Dr. Jean Star will help explain how to fix cavities. All that, plus a brand new Mystery Sound!
