    Choose the Best Teeth Whitener

    By Lisa Hill

    Are your pearly whites not quite as white as you’d like? There’s a lot you can do to turn your stained or yellowish choppers into brighter, dazzling ones.

    “You can see why whitening is so popular. It works for most people,” says Edmond R. Hewlett, DDS, an associate dean at the UCLA School of Dentistry.

    When Should I Take My Child to the Dentist?

    Q. How old should my child be before I make his first dental appointment? A. You should take him in by the time he celebrates his first birthday. First visits are mostly about getting kids used to the dentist's chair and educating parents about how to care for baby's teeth. If your child has transitioned from the bottle to cup and doesn't snack or drink in the middle of the night, you get a one-year pass, until age 2. That's when the standard every-six-month dental visit recommendation...

    Some of your best bets to do it? You could get a professional bleaching at your dentist’s office, apply a home-use product from your dentist, or use over-the-counter whitening strips. The right option for you depends on how much you want to spend and how quickly you want to see results.

    Option 1: Go to a Pro

    Your dentist will use a much stronger whitener than anything you could get at the store or online.

    Whitening gels used by dentists usually have a 25% to 40% concentration of hydrogen peroxide, says Yiming Li, DDS, PhD, professor of restorative dentistry at Loma Linda University School of Dentistry. That’s the stuff that changes the color of your teeth.

    The gel stays on for 15 or 20 minutes. That process is repeated once or twice. Sometimes the dentist aims a light at your teeth to speed up the whitening (although most studies show the lights don’t do much). This whole treatment costs around $500 or $600, but many dentists offer discounts to attract new patients.

    Hewlett says you should see a difference about 45 minutes.

    Victor K. Ryoo, DDS, owner of Ryoo Dental in Fullerton, CA, has seen varying results with in-office bleaching.

    “People expect that they’ll come in for an hour and that their teeth will be dazzling white and that’s not the case. It will always depend on what the starting point is and what their habits have been in the past,” including whether they're heavy coffee drinkers or drink red wine, he says.

    Option 2: Takeout

    Your second option is to ask your dentist to give you a take-home treatment. He’ll take an impression of your teeth and use that to make a fitted tray. The whitening gel goes inside the mouth guard. It comes in several strengths. You can wear the guard while you’re asleep if you have a lighter gel, or for 30 minutes to an hour each day if it’s a higher-power option.

    Only 18.5% of Americans never floss. You are missing out on a simple way to make a big difference in the health of your mouth. Regardless of how well you brush, plaque still forms between your teeth and along your gums. Floss removes food trapped between the teeth and removes the film of bacteria that forms there before it turns to plaque, which can cause inflamed gums (gingivitis), cavities, and tooth loss. Try flossing just one tooth to get started.

    You are one of 31% of Americans who don't floss daily. You are missing out on a simple way to make a big difference in the health of your mouth. Regardless of how well you brush, plaque still forms between your teeth and along your gums. Toothbrush bristles alone cannot clean effectively between these tight spaces. Flossing removes up to 80% of the film that hardens to plaque, which can cause inflamed gums (gingivitis), cavities, and tooth loss. Aim for 3 more days!
