Teeth whitening or bleaching is a cosmetic procedure which can be done by various methods, with or without the use of lasers.... the treatment duration can be somewhere around 30 to 45 minutes.... the results last for 10 to 12 months approximately, but that period is variable depending on the chemical composition of your teeth as well as your dietary habits...... the treatment cost also varies from dentist to dentist, depending on which technique is being used..... please consult your dentist for the options available.... also there is no scientific method to predict the actual tooth shade improvement and that varies from patient to patient even with the same technique.....
