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.
