Teeth that have lost their white appearance can cause significant psychological damage. The social norm is that teeth are white and when they are not one can quickly lose confidence. A bright-looking white tooth is then considered, sometimes wrongly, to be healthier than a yellow tooth, which evokes bad habits of life.
Thus, teeth whitening is often more aesthetic, except when it is linked to dental scaling. A whitening procedure is necessary to have white teeth. Bleaching involves either removing an outer layer that has accumulated on the enamel over time (tobacco, tartar, dental plaque) or to apply whiteners on the enamel to accentuate the white color.
The most used product is oxygen peroxide, which is often associated with blue rays with the particularity of accelerating the work of the peroxide. Another widely used bleaching agent is carbamide peroxide, a compound three times less potent than oxygen peroxide but easier to handle. Laser teeth whitening costs make the procedure more attractive to individuals.
