Keep Smiling!

Because the surface of your teeth is so slick that it's very hard for anything to stick to them. Even when candy sticks, it's because it gets into cracks (wedged in). Your face, on the other hand, has many tiny pores that make it easy for your gum (or your lunch) to stick to it.
Your teeth are covered with that's rather like new, shiny paint. It's hard for anything to stick to a surface like that. Once you sand it, though, making the surface rougher, then things will stick. |
