Dr. Oz Tip #7

Brushing is Not Enough

If you plan to spend your later years eating more than yogurt and applesauce, invest in some floss. No matter how thoroughly or long you brush your teeth, you're missing a good portion of their total surface. That's like washing one armpit after a workout. But the dangers of skipping floss go beyond hygiene: The bacteria that linger can increase your risk of heart disease. I use Reach Ultraclean floss, which stretches to glide between teeth.
