Thank you, george. Now, two secrets for brightening your smile. Whitening your teeth at the dentist does not come cheap. What if we told you that the key to sparkling pearly whites might be in your kitchen? Becky worley shows us. Reporter: The pursuit of the perfect smile. To get those pearly whites extra white, dental and drugstore treatments can be expensive. Awkward. But secret foods to make teeth sparkle? Actually, easy. They're already in my kitchen. Let's start with snacks. Like some of your favorite fruits and vegetables. Apples, celly and carrots. Theyork by scrubbing your teeth clean with their crunchyness. They stimulate the saliva in your mouth. The saliva will wash away plaque. Reporter: And mint leaves contain min tall compounds that can cover your teeth and protect them from stains. This stuff is preventing stains. Great excuse for wine and cheese. Snack on a cube before drinking your wine. The cheese coats the teeth with a film that guards against stains. Now, for my very unscientific experiment. Wine, cheese. My right front teeth have cheese on them. The left, don't. The left side has more spots from wine residue. Now, for home remedies.

Dairy products being, if you eat a piece of cheese before, you're protecting the red wine. But also on the milk, add it to your coffee and it protects the protective film on your teeth so it's loose for staining. That's a great tip. These are the blockers. And the green leafy, is also, not many people realize. But kale, broccoli, base basil, contains a film on the teeth. Normally, when you say film on the teeth. It sounds nasty. But this is a good thing. Here, you have the acid group. These are the lifters. Lemons and oranges, all lift off, just like your dishes. What you may not know is strawberries contain acids. Rub them on. Eat them. They're great for your teeth. We want to thank you, greta, for being with us. Coming up, a scathing review for guy fieri's restaurant just
