How does the laser in laser teeth whitening actually work? i've been using at home whitening kits, which work alright, but would like to try something else. i'm having a hard time figuring out how the laser actually whitens teeth.

Typically, : Typically, an actual laser is not used. Usually a proprietary ultra-violet light is used to activate the bleach that is placed on the teeth. The end result is similiar to the home whitening kit but is finished in about 1 hour vs. 2 weeks. I found you get quicker regression of color with the 1 hour system than the home whitening kit.

There : There are several in-office whitening systems. They all work the same basic way - the light activates the peroxide solution to make it work better (more quickly and effectively). I have used several in my office and the far and away best system has been the zoom system. Regarding quicker regression of color, i find that havin my patients use the trays i provide once or twice after the in-office treatment really locks in the white. They then also have trays for later touch up.

It : It is not the light that whitens your teeth (which is usually not a laser). The light activates and energizes the peroxide molecules which are responsible for removing the stains.

Lights work: The new zoom! system, that i use, has led light, not laser. Their own whitening agent is designed to work in conjunction with their light. Expect about 4-8 shades lighter (if your teeth are yellow or tan in color. If you teeth are gray or blue tint, then you may only get marginal improvement). I always want my patients to use custom trays after to get their teeth whiter & to use, as needed.

Works as catalyst: lasers are used as a catalyst to activate whitening gel to penetrate and whiten the tooth. My advise is to ask your dentist.
