If you want to have nice teeth, you'll have to do this:

Every moring, every afternoon and even every evening, you have to brush your teeth clean( if you want to have a nice, clean and shiny teeth). Also, you have to eat a lot of vegtables, heathy food. And one thing too, try not to eat fast food like: hamburger, french fries, chicken,... It isn't good for your teeth and your heath. If your teeth hurt, you have to go to see dentist so they can check yours...
