Being a Kindergarten teacher, this is something that is taught during March or April when we talk about body Health and teeth. I usually go to a local dentist to see if I can get student toothbrushes donated to my class. I do spend the time teaching my kids how to brush their teeth as well as when. We keep these brushes as well as some tooth paste is kept in the classroom for a week for the kids to brush at school before taking them home. My school also has a dental program that comes to the school for free dental checks.
