WHY LASER TEETH WHITENING IS FASTER COMPARED TO AT HOME TEETH BLEACHING
There are many different types of teeth whitening solutions in the market right now. The expensive laser whitening treatments that everyone has heard of, well to be honest, there are clinical studies that have shown that they provide faster results but does not result in whiter teeth compared to non-laser based whitening and teeth bleaching gel in the long run. While the latter two treatments take a longer time for whiter teeth and a fabulous smile to show up, the results are no worse with respect to the more expensive laser cleaning.
Basically the laser teeth treatment uses high intensity light energy to activate the bleaching chemical hydrogen peroxide that releases oxygen into your teeth dentin which then whitens this dentin layer (the outer protective enamel layer is generally colorless). If you remember your elementary chemistry, all chemical reactions require energy in order to take place. That is why it is known as 1 hour teeth whitening, much faster compared to all other types of cosmetic teeth whitening because of all the energy provided by the laser light equipment. On the other hand, bleaching gels and teeth tray rely on the heat from our bodies (the mouth area) to activate chemically and its intensity is much lower compared to the Britesmile laser. The dentist can also control the energy intensity easier in order to speed up the teeth whitening for patients with really bad stained teeth. It is really kind of difficult for you to heat up your mouth by pressing against a warm cup or something during your at home teeth whitening.
