While certain laser technology can indeed cause this type of damage, we must remember that they are specifically engineered for that purpose. Most lasers, including those used in dentistry, are engineered and designed to perform special functions without changing or damaging the surrounding tissues or materials. Think, instead, of the lasers used around us everyday, such as those found in the barcode scanners at the grocery store or those that make CD music possible.
Lasers deliver energy in the form of light.
In dentistry, these targets can be enamel, decay, gum tissue, or whitening enhancers. Each one absorbs a different wavelength of light while reflecting other wavelengths. No measurable effect is seen beyond the intended target site. Lasers are very specific in regard to the wavelength produced. This means that there must be a different laser for each type of procedure that you want to complete.
