In fact, for a few years now, the laser has taken hold in numerous fields of medicine, including that of "aesthetic dentistry," in which it constitutes a "technological alternative to the classic professional bleaching (or whitening).
(H2O2) on the surface of the teeth. The same gel, activated by the laser, releases free radicals that penetrate through the dental enamel and reach the pigmented molecules of the teeth - responsible for stains or their yellowing - shattering them through redox reactions; as a result, the teeth appear whiter and shinier.
In the light of what has been said so far, it should be noted that the real whitening action is to be attributed to the gel and not so much to the laser which, on the other hand, simply acts as an "activator" of hydrogen peroxide. In other words, the laser acts as a catalyst for the chemical reaction that leads to the formation and release of oxygen that will penetrate the teeth, eliminating their stains.
The "actual" whitening "of the teeth is visible immediately after the first session with the laser and, in the following days, the aesthetics of the smile further improve.
, advancing age, drug treatments (especially antibiotics) and the administration of particular foods or drinks - such as coffee, tea, licorice and artificial coloring - end up ruining the aesthetics of the teeth.It is in these circumstances that the use of lasers is one of the many methods indicated for whitening teeth.However, it should be pointed out that laser whitening does not offer any further advantage over the classic professional Bleaching strategies.

In any case - if the doctor establishes the patient's suitability for laser teeth whitening - before proceeding with the treatment, it is necessary to perform a deep professional cleaning, in order to eliminate all traces of tartar and / or plaque.
After cleaning, the dentist will have to determine the color of the patient's teeth by comparing the color of the latter with a special standard color scale.
In the 4-5 days following bleaching, it is strongly recommended to avoid the intake of soft drinks with artificial colors, coffee, licorice, red wine and black tea. Smokers, on the other hand, should abstain from smoking for at least the entire week after. treatment.

For this purpose, the most suitable are sage, sodium bicarbonate, ash, strawberries and apples: these products, in contact with the surface of stained teeth, can help to maintain the whiteness of the teeth produced by the laser for longer times.
After a couple of years from the laser whitening treatment, it is possible to remove the stain again with alternative chemical techniques. For this purpose, whitening pens or stripes (available in pharmacies) are particularly suitable.
Furthermore, the dental masks coated with carbamide peroxide, applied directly on the dental arches as if they were removable appliances, can further improve the color of the teeth.
