What is laser teeth whitening all about ?

Laser teeth whitening (also known as light-activated teeth whitening) is one of the newest - and more expensive - methods available for teeth whitening. Laser treatment involves using a beam of special laser light on the desired areas of the mouth. Laser teeth whitening is popular because the procedure only takes an hour, and results can be seen instantly. The treatment begins by using bleaching agents like hydrogen peroxide gel or carbamide peroxide gel on the tooth enamel. The gel is then activated using a controlled laser light. The result is a faster, more effective procedure with results of up to a 10 shade improvement.

Below are the top three laser/light-activated teeth whitening procedures available on the market:

There are two schools of thoughts on light-activated whitening. Some studies show that it works and some do not. Many respected researchers in dentistry, including CRA (Clinical Research Associates), have performed split-arch, showing that bleaching lights are of no benefit. A split-arch study is when you do one treatment on the left side of a patient's mouth and another treatment (or no treatment) on their right side. In this particular CRA study, bleaching gels were placed on both sides of a patient's mouth, but only one side was exposed to a bleaching light. The result? No difference from right side to left side. The study showed that it was only bleaching gel that caused the whitening. However, there are studies out there by credible institutions that show laser whitening does actually work.
