    Teeth Whitening

    Should You Whiten Your Teeth? continued...

    Gum disease, worn enamel, cavities, and exposed roots. Individuals with gum disease or teeth with worn enamel are generally discouraged from undergoing a tooth-whitening procedure. Cavities need to be treated before undergoing any whitening procedure. This is because the whitening solutions penetrate into any existing decay and the inner areas of the tooth, which can cause sensitivity. Also, whitening procedures will not work on exposed tooth roots, because roots do not have an enamel layer.

    Fillings, crowns, and other restorations. Tooth-colored fillings and resin composite materials used in dental restorations (crowns, veneers, bonding, bridges) do not whiten. Therefore, using a whitening agent on teeth that contain restorations will result in uneven whitening -- in this case, making the teeth without restorations appear lighter than those with restorations. Any whitening procedure should be done prior to the placement of restorations.

    People with numerous restorations that would result in uneven whitening may be better off considering bonding, veneers, or crowns rather than a tooth whitening system. Ask your dentist what strategy is best for you.

    Unrealistic expectations. Individuals who expect their teeth to be a new "blinding white" may be disappointed with their results. Smokers need to be aware that their results will be limited unless they refrain from continued smoking, particularly during the bleaching process. A healthy guide to is to achieve a shade slightly whiter than the whites of your eyes.

    Darkly stained teeth. Yellowish teeth respond well to bleaching, brownish-colored teeth respond less well and grayish-hue or purple-stained teeth may not respond to bleaching at all. Blue-gray staining caused by the antibiotic tetracycline is more difficult to lighten and may require up to six months of home treatments or several in-office appointments to successfully lighten.

    Teeth that have dark stains may be better candidates for another lightening option, such as veneers, bonding, or crowns. Your dentist can discuss the options best suited for you.

    Risks Associated With Whitening

    The two side effects that occur most often with teeth whitening are a temporary increase in tooth sensitivity and mild irritation of the soft tissues of the mouth, particularly the gums. Tooth sensitivity often occurs during early stages of the bleaching treatment. Tissue irritation most commonly results from an ill-fitting mouthpiece tray rather than the tooth-bleaching agent. Both of these conditions usually are temporary and disappear within 1 to 3 days of stopping or completing treatment.

    If you do experience sensitivity, you can reduce or eliminate it by:

    • Wearing the tray for a shorter period of time (for example, two 30-minute sessions vs. two 60-minute sessions).
    • Stop whitening your teeth for 2 to 3 days to allow teeth to adjust to the process.
    • Ask your dentist or pharmacist for a high fluoride-containing product, which can help remineralize your teeth. Apply the fluoride product to the tray and wear for 4 minutes prior to and following the whitening agent.
    • Brush teeth with a toothpaste made for sensitive teeth. These toothpastes contain potassium nitrate, which helps soothe the teeth's nerve endings.

    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!
