Everyone wants a sparkling, white smile - but that gorgeous grill can cost you. Dental procedures can range from $200-$1,000, depending on whether you continue treatments at home or have it all done at the dental office. Regardless, you can get comparable results at home with commercial whitening kits and even homeopathic remedies. For example, Catherine Zeta-Jones keeps that movie-star smile by crushing up strawberries and brushing them on with a clean toothbrush, then rinsing and flossing. You can follow her lead or try other home remedies, like baking soda paste and even salt. Experts value whitening toothpaste for their ability to clean plaque; however, their efficacy at changing the shade of your teeth is questionable at best.

They simply don't spend enough time on your teeth to make much of a difference in the shade. That's where whitening trays and strips come in. Strips seem to come out on top in online reviews of whitening products. They adhere best to teeth without creating too much of a distasteful mess. The longer you're able to keep a whitening product on your teeth, the better the results will be. Crest 3D Whitestrips Professional Effects seem to come out on top. They're pricey at about $45 per kit, but coupons are available, and it's still a fraction of the cost of a dentist visit. Reviewers recommend cutting the strips in half lengthwise to help stretch their use. Many people experience sensitivity to hot and cold while using these products - using once a day instead of twice, as directions indicate, may help.
