The 10 Commandments of White Teeth

BRUSH THE RIGHT WAY

Believe it or not, the way most people brush their teeth strips enamel, which can make teeth yellow over time. Here's how to keep them pearly white: First, whether you use an electric or manual toothbrush, make sure it has a soft head. Hard brushes are like sandpaper on your enamel. Next, if you only spend a few seconds brushing your teeth, it's time to step it up: The American Dental Association recommends brushing for two minutes at least twice a day— gently. Scrubbing teeth like a frying pan not only wears on your enamel, it's bad for your gums. If you're feeling extra virtuous, brush after lunch.
