There is a sharp rise in the acceptance and demand for treatment of otherwise healthy teeth to make them brighter and whiter. Bleaching, now a days, is the single most common esthetic treatment for adults. It is estimated that more than a million people have had their teeth bleached by dentists, while perhaps a million more have tried their own hand at bleaching with over the counter products. The popularity of bleaching is easily understood. For the appropriate patient, with careful diagnosis, case selection, treatment planning and attention to technique, tooth bleaching is the simplest, least invasive means available to lighten the color of teeth and diminish or eliminate stains in both vital and non vital teeth.
