If you have ever bitten into some ice cream or taken a sip of hot coffee or coco and experienced excruciating pain from one or more teeth, then you most likely have sensitive teeth. 

Don't take our word for it though, go see a dentist to be sure and while you are there don't forget to ask if desensitizing toothpaste is right for you.

Well, it all has to do with science. Chemistry to be more exact. 

Watch this short, but interesting, SciShow video to learn the magic behind this pain relieving wonder of science.
