There are many reasons why teeth may need a whitening treatment to achieve an appealing brightness: what we eat and drink, natural aging, genetics, and the lack of dedication to oral hygiene can all play a role in how we look.

For vital (living) teeth, there are basically three different options for teeth whitening, and we’d be happy to help you decide which is right for you:

• In-office tooth whitening: The fastest way to get your smile radiant. A high concentration of a peroxide gel solution is applied directly to the tooth surface. Gums and other soft tissues are completely protected for your safety. This technique is excellent for whitening deep surface stains as well as general tooth whitening. This professional treatment requires the least amount of time to achieve the desired whiteness.
• The professional take-home option: Custom-made bleaching trays are prepared by our office. This technique is convenient and less expensive, but the desired whiteness will take longer to achieve than the in-office option.
• Over-the-counter products: These offer the least expensive option but use weaker whitening agents. For example, whitening strips, like the ones advertised on television, are popular and easy to use but will generally take the most time to achieve the desired success. Also, even agents that are not the strongest available may cause damage to teeth if used inappropriately and without professional supervision.

While there are normally no serious side effects after professional whitening treatments, there is a potential risk of tooth sensitivity and gum irritation. If either one or both of these occur, it should disappear within a few days.

It should come as no surprise that bleaching is not permanent. The whiteness will fade eventually depending on your diet, habits, hygiene, etc., but it usually will last at least six months — more often up to two years. Obviously, if you avoid drinking coffee, tea, or red wine, don’t smoke, and have a diligent oral hygiene routine your results may last longer.

Advertisements for teeth-whitening products are everywhere.
