8 Home Remedies for Whiter Teeth

©2007 Publications International, Ltd. Coffee, tea, and cola are notorious for leaving stains on your pearly whites.

Pearly whites gone dingy are one of the most common complaints dentists hear from their patients. But what causes stained teeth?

Tobacco -- whether it's smoked or chewed -- is one of the worst offenders. Coffee, tea, and colas are culprits as well. Other possible causes include fruit juices (especially grape), red wine, fruits such as blueberries, soy sauce, and curry. Think of it this way: If a food or beverage can leave permanent stains on clothes or carpets, it can probably taint your teeth.

Aging also contributes to the yellowing of teeth. The enamel, which is the hard outer coating of your teeth, wears thin, allowing the underlying layer of yellowish dentin to show through.

And some stains are what's called intrinsic. That is, they actually occur on the inside of the tooth. For example, children who take the antibiotic tetracycline (or whose mothers took it during pregnancy) often have such stains. Silver-colored fillings can sometimes leach out and stain the surrounding tooth.

Some folks simply go ahead and take matters into their own hands, risking damage to their teeth and gums in the process. Before you can safely take action, however, you have to understand what kind of stains are dulling your teeth. And you need to be realistic, too, in what you seek: Even the healthiest, most perfectly maintained teeth are not pure white.

Only your dentist can correct intrinsic stains, through the use of such cosmetic procedures as composite resin bonding and porcelain laminate veneers (which essentially cover the offending colored area with opaque material). Stains from food and drink can often be removed with a professional dental cleaning. A more expensive and time-consuming option is in-office bleaching.

Once you've had the stains removed, follow the home remedies below to keep them from occurring in the future.

Keep your teeth clean. That means daily brushing. An electric toothbrush may be more effective if you don't do a thorough job manually. But don't get carried away; bearing down too hard when you brush or using a hard-bristled brush can create grooves in the teeth at their roots. You can brush with a light touch and still do a thorough cleaning job.

Floss. Ever notice how stained teeth look worse around the edges? That's because the plaque (a thin, nearly invisible layer of bacteria and food debris) that accumulates between teeth and at the gum line attracts stains like a magnet. Limit plaque with flossing, and you'll fight stains, too.

Quit smoking. Much easier said than done, but if you won't stop for your health, will you do it for a more attractive smile?

Be wise about beverages. You know how coffee can stain a porcelain cup. It, along with tea and colas, does the same thing to your teeth. When you do indulge in staining beverages, do so in one or two sittings rather than sipping such drinks throughout the day. And brush after drinking them.

Use a straw. Okay, you may not want to try this with hot coffee, but sipping iced tea, cola, and fruit juices through a plastic straw will reduce your teeth's exposure to these staining beverages.

Use stain-removing toothpastes with caution. So-called smokers' toothpastes, designed to scrub away tobacco, coffee, and other stains on the teeth, are generally abrasive (unlike most of the newer "whitening" products, discussed in the next section) and should be avoided in all but the most serious cases of stained teeth. Even then, dentists usually recommend using these products no more than two or three times a week. You may want to check with your dentist before you try one of these.

Get a "cosmetic cleaning." If your teeth stain easily, call your dentist for a cosmetic cleaning between checkups. The procedure takes about 20 minutes and costs about half the price of a regular cleaning. (It is not, however, meant to take the place of regular checkups.)

Don't get creative. Brushing with baking soda can scratch composite resins and porcelain veneers (which are used to make crowns and other types of tooth restorations). Scratches on these materials pick up stains more readily. Other home treatments that can spoil smiles include dental picks and applications of chlorine bleach.

There are safer home remedies to try to whiten your teeth. In the next section, we will discuss some of the new at-home whiteners that are available.

If your smile has lost its sparkle, you may be tempted to use one of the many tooth-whitening kits sold in pharmacies, supermarkets, and on the Internet. These products come in a variety of styles. Some are gels that you either paint on, tooth by tooth, or squirt into a mouth tray (similar to the mouth guards athletes wear), which you then wear, sometimes only at night, for a prescribed period (usually two to four weeks). Similarly, you can purchase dental whitening "strips," which are thin, flexible bands of plastic that adhere to the teeth. You can even find "whitening pens," which have sponge-tips through which you apply the whitening agent.

Many dentists were initially skeptical of at-home whitening systems, but now many of them not only accept such do-it-yourself systems, they dispense them to patients for use at home. Kits for use at home, whether sold at a store or dispensed by a dentist, tend to contain 10 percent carbamide peroxide. The peroxide "bleaches" the teeth to remove surface discolorations as well as many deeper stains; it penetrates the tooth to eliminate stains that have accumulated over the years.

Dentists can perform a similar bleaching in their office, using products that contain higher concentrations of peroxide than are found in over-the-counter versions. Studies suggest that higher concentrations of peroxide do a better job of brightening teeth. What's more, dentists can use lasers and light, which reportedly intensify the peroxide's effects. Plus, while the at-home remedies can take weeks to achieve results, bleaching done in the dentist's office can usually been completed in a single session of about an hour. Then again, the dentists-administered version costs more.

Bottom line: According to the American Dental Hygienists' Association, 96 percent of people who have stains caused by age; tobacco; coffee, tea, or other beverages will notice at least some lightening after using tooth whitening agents/kits. However, these products are less effective on stains caused by medications (such as the antibiotic tetracycline) and fluorosis (the result of overexposure to fluoride). It's worth noting that these products will only work on natural teeth, so they will not whiten caps, crowns, veneers, fillings, or dentures. Also, people who wear braces should not use dental whiteners.

Although the idea of putting peroxide in your mouth just for whiter teeth might seem extreme, these products appear to be safe, with few risks. The American Dental Association has placed its ADA Seal of Acceptance on many such products, which can help guide your selection, but the association does advise patients to try a bleaching product only after consultation with a dentist. Bleaching can cause temperature sensitivity in the teeth. And people who use mouth-tray kits occasionally develop gum irritation. But these problems appear to be short lived. (There have been rare reports of permanent tooth damage from the higher-concentration, dentist-applied whiteners.) If you try an at-home whitening product, follow the instructions and don't apply it more often than recommended; overexposure can damage tooth enamel.

In addition to whitening kits, you can also find many whitening toothpastes. These may help eliminate surface stains, but they can't alter a tooth's color and probably won't produce dramatic changes. And beware of toothpastes that use abrasive ingredients to "scrub away" stains; they may damage teeth.

The best way to whiten your teeth is to make sure they don't get stained in the first place. By dropping a few bad habits and following our home remedies, you can have a glistening white smile.
