I've read a lot that coffee stains teeth, but how much coffee does it take for it to really do some damage to your teeth? I drink occasionally, once a week, and I don't want to get nasty stains. I'll stop if I find out it really will damage them. So, should I stop drinking once a week, or will I be okay? I brush twice a day, that should be so useful information.
