Here's a question I have been debating with a friend for a while, and seeing as how I'm not scheduled to go to the dentist again for a while, I thought you could shed some light on the issue: when brushing one's teeth, should one also brush one's tongue? I would think yes, because what's the point of brushing germs off teeth if the tongue still has them there, and will transfer them to the teeth as soon as you're done brushing. My friend thinks it makes absolutely no difference. So does it matter? We have an ice cream wagered on this one! I hope I'm right!
