Whitens the teeth: Your dentist applies a teeth whitening gel and points the laser at the teeth, the light removes the yellow stains.The laser light is used to enhance the penetration of the whitening gel into your teeth enamel, thus improving the result if the tooth bleaching.In most cases , you do not need further treatments.

Not much: There are effective techniques that do not use the laser or light, and yield fantastic results! in my experience, they add to the likelihood of post treatment sensitivity and dry out the teeth.

Not laser: Usually it is not a laser that is used for in-office whitening, but a light source such as gas plasma, plasma arc or led light sources that activate the ingredient in the gel for a more rapid result (think britesmile, rembrandt or zoom). While lasers were used more when whitening first started, it is more time consuming and done one tooth at a time with laser.

Questionable...: The lasers may activate the whitening gels. However, to be honest, the use of lights and lasers for gel activation is losing favor. It seems the gels activate just fine on their own. The gels without lasers nor lights are very safe and effective when properly used.

Is laser teeth whitening safe?

Yes: Laser tooth whitening has been shown to be safe, but is it effective. In the short term it is. Over longer periods of time, the stains can return to your teeth. Often laser whitening should be followed by bursts of use of custom trays with whitening gels to obtain a more long term result. You need a thorough oral evaluation to see if you are a candidate for whitening first.

Tooth whitening: First of all, actual 'lasers' are not used to whiten teeth. They are intense white lights. There are many ways to whiten teeth and include otc whitening strips, in-office techniques as well as take home whitening gels in custom trays, just to mention the more common methods. See a dentist to find out what would be best for your needs.

What is the definition or description of: laser teeth whitening?

See the long answer: Tooth whitening that is performed with the aid of a light (such as the zoom light) is called laser tooth or teeth whitening. From a pure scientific standpoint, the light does absolutely nothing. It is a marketing tool to make you think that the light is doing something. Tooth whitening is accomplished by using powerful oxidizing agents. The agents that are good must be applied by your dentist.

It is also not a laser, but a regular light. Some products like Luma Cool use an LED light.

Every study I have read indicates that the "light" of whatever form is unnecessary. It is the bleaching agent that does the work. Anything else is "just for show".

The salesperson who sells me Zoom says it heats up the bleaching agent, but I doubt it really does anything.

Sensitivity: Other than some sensitivity to cold, there isn't any damage that occurs. Whitening is temporary regardless of the method used.
