The con's range from an allergic reaction to the bleaching gel, to the cost. Lasers are not just for James Bond and military applications. Laser teeth whitening has helped thousands of individuals who were not proud of their teeth and rarely smiled when asked to pose for a picture.

Some may have avoided pictures completely because they felt very self-conscious. Professional whitening may cost more than those strips, but the results are immediate and you will have the smile you have always wanted.

It takes only about an hour for this whitening procedure to be completed. Most patients sometimes do not need to go back for more sessions.

Completion of work in a single session is often possible for dentist teeth whitening, but for some cases of severe staining, this one session will definitely not be enough. After you have finished your whitening session, your laser dentistry professional could also provide you with a touch up kit that you can purchase. The kit will be used for touch up areas that may get stained again once you get home. A lifetime treatment option will allow you to get touch ups whenever you think it is necessary and some dental offices may offer you this option. This ensures that you can have the whitest smile, with little cost and time involved on your part.Whitening your teeth is not a new concept and it is something that has been used throughout the ages, particularly by the upper class. While original formulas included things like nitric acid, pumice and human urine among other ingredients, teeth whiting products these days are far more benign, yet still effective.

For celebrities, tooth whitening is part of their preparation for their job. While some go so far as to have cosmetic surgery to improve their faces, it´s far more common to hear about celebrities getting their teeth whitened.

These are all regulated, though, and tend not to be nearly as effective as those used by the dentists. Which is why you´ll never hear about celebrities doing those home kits.

When you are rich and famous, only the best tooth whitening techniques will do and most celebrities opt for the more expensive options, which usually means near-instant, as well. High end tooth whitening techniques like laser whitening are the most popular among the stars who have money.Toothpastes that offer to whiten teeth are also effective in keeping the teeth cleaner and, therefore, looking whiter. The latest high-tech option in tooth whitening is laser tooth whitening. Needless to say, the tooth-whitening toothpaste is the cheapest option when compared to all these other treatments.

It is advisable to first confirm with the dentist the best method. People with joint problems and high sensitivity to hot and cold foods or drinks as well as those with crack lines in their teeth are better advised against tooth whitening.

Laser teeth whitening works by focusing a laser light on a specific bleaching gel that is applied directly to the surface of them. The light speeds the bleaching process and helps the whitening gel permeate the enamel.

Discoloration of the teeth is a process that takes years, until the natural whiteness of them is greatly diminished. It may have taken years of drinking coffee to turn them in an ugly color, but usually one office visit can yield a brighter smile that is noticeably whiter.

Obviously the pro's of professional teeth whitening is that your smile, now whiter and brighter, will give you a more youthful appearance.
