This TED-Ed Lesson is a Horror Story

You can tell this is a horror story because it features toothy green monsters and is narrated by a skeleton. But as an adult, you should also know that nothing good can come of going a long time without brushing your teeth. Your mother told you that if you didn't brush every day, your teeth would fall out. That really hit home when you turned six and your teeth fell out. But that second batch of teeth have to last a lifetime. Scientists can explain exactly what happens in your mouth to cause unbrushed teeth to fall out, and it's not pretty. Furthermore, rotten teeth and infected gums can affect the rest our bodies as well.
