As we know, there are two types of teeth whitening: one that can be done at home, since it is following the correct instructions dentist, and what is professional dental space by halogen lights (white and light) laser (light amplification by stimulated emission of radiation) or LED.
In the office, the dentist uses a patient’s gum shield (so the whitening gel does not come into contact with the gums and lips), and then apply the gel on the teeth (carbamide peroxide), formulated at a concentration of bleaching molecules called “free radicals“. Thus, in any bleaching process, free radicals – which are reactive in nature – pigmented compounds decompose have stayed in both the enamel and the inner layer of the tooth – dentin.
Using laser after applying the formulation, the most common reason is that light amplification by stimulated emission of radiation effects occur faster than light beam activate the product and accelerate the whitening process.
The fact, however, there is no impact on the application of laser whitening gels, whitening occurs because of a chemical reaction of the substance itself (carbamide peroxide), with or without using it. Laser, in particular, has a pre-whitening action itself, but the sensitivity of the procedure by reducing it further.
