Whether your teeth are stained from coffee or tea, smoking, or discolored due to natural pigmentation or antibiotics– there are various teeth whitening methods you can do at home or at your dentist’s office to bring back that bright smile. Since a smile is an important part of your appearance and teeth can become stained over time, teeth whitening or bleaching has become more popular in recent years and a normal part of dentistry, especially cosmetic dentistry.

Teeth Whitening methods normally involve an oxidizing agent to bleach the enamel, and needs to be done every several months to keep the smile maintained. The enamel will resume absorbing of foods and beverages since the enamel normally becomes more porous after whitening.

Of course, there are all kinds of teeth whitening toothpaste on the market today for day-to-day use, but those may do little to reverse noticeable discoloration– although some are a bit stronger than others, and usually contain a slight peroxide type agent or abrasives. There are also over-the-counter teeth whitening systems which are stronger than the paste, and often involve a type of teeth bleaching process. That is normally done over a period of time, until desired results are achieved.

There are paint-on types of bleach and there are now whitening strips, to make it easier. Some home teeth whitening methods involve a mouth guard type tray that is used a few hours per day. The duration is normally anywhere from a week to three weeks or longer, and one disadvantage of the home systems is that the bleaching tray is not custom fit, so uneven whitening can occur or enamel near the gum line does not get bleached, resulting in a distinct line.

There are different kinds of teeth whitening methods that are done in the dentist office, as well. There is a gel-based method, where the gel is applied and a laser light activates the gel to produce bleaching. A cosmetic dentist can also make custom, at-home bleaching trays and systems that need to be under the dentist’s care and can be monitored. This is especially important for patients with sensitive teeth, as bleaching can make them more sensitive to hot and cold. In addition, it is possible to cause damage to the enamel of the teeth from over-bleaching, so a cosmetic dentist is able to monitor any damage.

Many of the professional bleaching processes can run from $100, all the way up to $2,000, depending on the system and amount of bleaching required. Many of the over-the-counter home teeth whitening methods are considerably less money, and of course, contain a lesser percent of the oxidizing agent than is used in the cosmetic dentistry treatments. Some patients will see results quickly and others may see little or no effect, depending on the cause of the discoloration.

It is usually best to consult with a cosmetic dentist, especially if you have any form of gum disease, dental fillings or crowns, or very important test, before the teeth whitening method to find the best way for you.
