UNDATED (CBS) -- Many people go to great lengths for a brighter smile, having procedures and using over the counter products. But there's a simpler way to get whiter teeth.
Doctors say certain foods act like nature's toothbrush, Dr. Michael Kosdon, a cosmetic dentist, explains, "Strawberries have acids in there that actually naturally whiten your teeth and foods like cauliflower also use almost sort of a scrubbing action on your enamel and help remove the plaque on your teeth."
Dr. Kosdon also suggests stocking up on oranges and pineapples because they have the same acids. They also help stimulate saliva, which washes stains right off teeth.
Eating certain foods can improve your smile. Yogurt and cheeses contain proteins that help prevent harmful acids from binding to teeth. Plus, they're packed with vitamins and minerals that keep teeth strong.
But there are foods and drinks you may want to avoid to keep your teeth from turning yellow. Dr. Kosdon explains, "Tea is probably the worst thing people can drink to stain their teeth. A lot of people think coffee is, but tea really just soaks up into the enamel and stains really bad."
Also on that list, anything red like red wine, cranberries, even marinara and hot sauces.
