Nowadays the most recommended technique is the activated whitening with cold plasma light. The products used are peroxide of hydrogen or peroxide of carbamide, products that remain totally innocuous for the tooth.
A unique 50 minutes session will complete the treatment with visible results. Surprised? We want to also let you know that the treatment can be repeated yearly.
These products are capable (through the light activation) to produce H²O² molecules that will “filter” through the enamel of the teeth, through the dentine tubules; there are approximately 15000 dentine tubules/mm². Thanks to this, the internal tissue (dentine) that provides teeth with its color is submitted to an oxidation process which will reflect into an instant whitening of the dental tissues. So, really we are talking about a “from the
inside” whitening technique. The best part of all is that the technique is damage free and your enamel will not suffer at all!
The intensity of the whitening will depend on each patient, depending on the particular original color of the teeth that must be studied by the specialist to decide the dental whitening expectations.
Almost all types of teeth respond well to the technique, besides those teeth with tetracycline staining (brown or gray colored).
But there is no need to worry as technology keeps moving forward on new advanced ozone and enzymatic dental whitening techniques.
