Teeth whitening is the most commonly requested cosmetic dentistry procedure. Teeth whitening falls into the cosmetic dentistry category because it is designed to enhance your appearance by reducing tooth discoloration and staining to elicit a brighter, whiter smile. You may feel that your teeth are too discolored to ever be white again, but cosmetic dentists are achieving amazing results with the newest whitening techniques.

The Prevalence of Tooth Discoloration

Tooth discoloration and staining is a relatively common problem. Teeth are porous and are therefore not stain resistant. Red wine, soda, coffee, and tea, among other food and drink, contribute to the discoloration of teeth over time. Medications such as the antibiotic tetracycline may cause significant staining, resulting in yellow, grayish teeth. Smokers' teeth can become permanently stained if the discoloration is not treated in a timely manner.

Tooth brushing alone can't brighten teeth dulled by years of exposure to such discoloring agents. In fact, people with dull teeth sometimes over-brush in an attempt to eliminate stains, and this can harm the enamel.

Teeth Whitening Considerations

More often than not, teeth whitening works adequately. Teeth whitening procedures performed by your dentist may potentially whiten your teeth up to 14 shades, correcting serious discoloration issues.Occasionally tooth discoloration is so severe that whitening alone cannot fully treat the problem. Such situations may require a combination of whitening and the placement of custom porcelain veneers on specific discolored teeth. You may opt for veneer treatment alone rather than a teeth whitening regimen. Consult with Dr. Ahmadi to determine the best course of action for your unique oral concerns.

Dr. Ahmadi will also advise you to avoid food and drink that could stain your teeth for about a week, as well as to refrain from smoking.

The Teeth Whitening Procedure: In-Office vs. At-Home

Teeth whitening can be performed either in-office by your dentist or at home by you. While in-office whitening is considered to be much quicker and more effective, many appreciate at-home whitening for its ease of use and low cost. How exactly do the two options differ?

In-Office Whitening

The advantage of having your teeth whitened in the dental office is that this approach is safe, fast, and most effective. Typically, your teeth can be whitened 8 - 10 shades within 45 minutes, dramatically improving your appearance in the shortest possible time. Shade charts are used during the consultation stage of treatment to customize the perfect shade of white for your teeth. In-office whitening is unique in this respect, as Dr. Ahmadi has more control over achieving your specific teeth whitening goals. During your teeth whitening procedure, you are made comfortable while your teeth are prepared.

At-Home Teeth Whitening

Although many people opt for the "once-and-done" approach to teeth whitening associated with in-office treatment, some people prefer the at-home method. The most effective at-home whitening system is a prescription-strength gel kit. Most kits contain mouth trays that you fill with the whitening gel and place over your teeth for up to four hours. At-home teeth whitening requires several hours of application over a 5 - 14 day period, and the results are typically not as satisfactory as those achieved with an in-office approach.
