WeighingtheProsandConsofTeethWhitening

Transforming your smile doesn’t necessarily require complex treatments like orthodontics, dental implants or porcelain veneers. Sometimes a little brightness can mean all the difference in the world.

Bleaching (or teeth whitening) is a proven method for dealing with tooth discoloration and staining. Nearly all whitening products, whether home or professional, contain the bleaching agent carbamide peroxide or its breakdown product hydrogen peroxide. These agents effectively diminish staining deep within a tooth (intrinsic) or on the enamel surface (extrinsic), although intrinsic staining will require a more invasive office procedure.

If you have extrinsic staining you have three basic options: dental office bleaching, a retail home kit or a kit purchased from a dentist. Again, you’ll find the same basic bleaching agents in each of these versions. The difference will be the concentration: home kits contain about 10% agent by volume, while the office application will be a much higher range of 15% to 35% (which may also employ specialized lights or lasers to increase the bleaching effect). As a result, an office bleaching may take only a visit or two to achieve the desired brightness while a home kit about two or three weeks.

Whitening is a more economical route for smile enhancement of otherwise sound teeth than other measures. But there are other considerations you should weigh before undergoing a procedure. Whitening isn’t a permanent fix — the brightness will diminish over time, optimally six months to a year in what dentists call the “fade rate.” You can slow this process by avoiding or limiting foods and habits that cause staining.

If you have other dental work — crowns, bridgework or fillings — it may be difficult to achieve a tint level that matches these restorations, especially at home. And while whitening is relatively safe (as long as you’re using your kit as directed), you may experience tooth sensitivity, gum irritation or other minor oral side effects.

Before you decide on whitening, visit us first for a complete dental examination. From there we can advise you on whether whitening is a good smile enhancement choice for you.

ProfessionalWhiteningOffersanEffectiveWaytoRestoreYourSmilesLuster

Your teeth were meant to shine! Tooth enamel’s polished translucence, framed by the dentin layer beneath it, has a way of vibrantly catching the light when you smile. But tooth wear and structural changes as you age can dim that shine. Add to that staining caused by foods and beverages or disease and your smile could further lose its luster.

On your supermarket or pharmacy oral hygiene aisle you’ll find dozens of products promising to restore that lost luster, including toothpastes, whitening kits or even chewing gum. While such products work to some degree, our dental office may have the right solution for you: a safe and effective treatment for whitening teeth.

Why see us for teeth whitening? For one, professional whitening solutions contain a higher concentration of bleaching agent (usually 35-45% hydrogen peroxide) than home kits. We usually apply it in a gel form directly to the teeth while using barrier devices like dams to protect the lips and other soft tissue from irritation. We may then apply heat or light to the applied gel to enhance the release of peroxide into your enamel.

This professional procedure can often give you a brighter smile in fewer sessions than a home whitening kit — and it may last longer. What’s more, we can control the level of brightness to produce only a subtle change or a dazzling “Hollywood” smile — whatever your preference.

Like a home kit, this procedure bleaches staining on the outer surface of enamel, known as extrinsic staining. But you can also have discoloration deep within a tooth, known as intrinsic staining, caused by a variety of reasons like tetracycline use early in life or complications from a root canal treatment. Home kits or even the professional treatment described above can’t whiten intrinsic staining.

For intrinsic staining you’ll need a special procedure that places a bleaching agent inside the tooth. Depending on the extent of staining the procedure could require more than one session.

To find out what kind of discoloration you have, visit us for a full examination. We’ll then be able to give you your options for putting the shine back in your smile.
