This is far from an exciting craft - sorry for the ugly pic. It is, however, important for the kiddos to learn about this stuff, and this is a great way to teach them about getting their teeth clean. You start with a yellow (or brown) tooth cutout. Glue that on to a piece of paper (or you can wait and put it on a colored paper after they are done if you want it to stand out better. Today was a professional day for teachers, so we wanted to take the day off of school too . . . so we hurried through craft time. To paint it, take white paint and an old toothbrush and have the kids BRUSH their teeth clean with the white paint. Encourage them to use circular motions and to cover the entire tooth. This tooth was painted by a 21 month old.
