Dental laser whitening introduction
Jun 04, 2018

Laser whitening is the use of higher concentrations of bleach (such as hydrogen peroxide), with appropriate laser doses, such as Nd:YAG lasers, catalyzed peroxides, bleaching effects that increase and accelerate peroxide action, and selective action For the pigment particles deposited on the teeth, the organic pigment in the teeth is bleached from the carbocyclic structure to a hydrophilic, non-pigment structure;

The light-absorbing macromolecules in the tooth structure are broken into small molecules so as to no longer absorb light and achieve a safe whitening effect. At the same time, appropriate doses of laser irradiation can seal the dentinal tubules, reduce the dentin permeability, and reduce the tooth bleaching process. Dentin-sensitive symptoms that occur in the body.
