Dental hygiene question
In one of my classes at school, my teacher is having everyone write about person hygiene and why it is important. It makes me wonder if she thinks she has students that stink or something. Anyway, I got stuck with dental health.
I know why we should brush and floss our teeth. My mom says we need to brush our gum line and our tongues too. Just my luck my mom is a dentist, so I know she is right. You think she help me more, but she says that is all the help she is giving me and that I need to find out why for myself. She is letting me use the Internet to find out the reason why. Any help would be nice.
