There are varying concentrations used in the lazer teeth whitening as well as different methods. The bleaching agents used in lazer treatments can contain hydrogen peroxide or carbamide peroxide. The effect of these chemicals can last six months to two years. Home teeth whitenings contain less effective and less intense chemicals so they usually last 4 to 6 months. You should get your lazer teeth whitening in Turkey and have your shiny smile for almost a couple of years. Afterwards, plan a short holiday to Turkey and renew your teeth whitening in Turkey without sacrificing both your pleasure and your health.
