  1. 1The road to whiter teeth begins with an ADA-approved whitening toothpaste. Several brands of toothpaste contain mild abrasives or gentle polishing agents and are useful at removing surface stains. Common everyday baking soda has also been used to clean teeth for years and can be effective at fighting stains, but be aware that baking soda can be harsh on sensitive gums and teeth.
  2. 2If your dentist gives you the green light, you can choose a product that contains carbamide peroxide or hydrogen peroxide. These products have a relatively safe bleaching effect on teeth and include gels, strips, tray-based whiteners, and rinses: Gels are applied with a small brush directly to the surface of the teeth.Strips are thin strips layered over the teeth for 30 minutes a day, for a 14-day period.Tray-based teeth whitening systems involve filling a mouth guard-like tray with a peroxide-based whitening solution and then wearing it for a 30 to 45 minutes a day for a couple of weeks or longer.Whitening rinses can be used like any other mouthwash but have the added advantage of reducing plaque and gum disease.All of these methods will take several days to show results and have their pluses and minuses depending on the time you’re able or willing to invest. Be sure to read and follow all label instructions carefully. Improper use could damage your teeth.
  3. 3Remember that all the whitening in world won’t make up for not brushing and flossing every day or seeing your dentist for a professional cleaning twice a year. Good dental hygiene is the most important step in keeping your teeth looking their best.
