Tooth whitening is one of the most common cosmetic dental procedures practiced across the world. It involves the removal of discoloration and stains on teeth. Tooth whitening has been gaining popularity since the 1990s. Dental whitening can be done by using bleach or without bleach. Bleaching products used for teeth whitening contain a peroxide agent– usually, carbamide peroxide. This bleaching product is available in peroxide concentrations of 10%, 16%, and 22%.
Peroxide present in the bleaching product helps in removal of surface stains and underlying stains and thus, whitens the teeth. Bleaching can be done at home or a dental clinic. Dental whitening agents that do not contain peroxide use chemicals or abrasive agents for removing surface stains on teeth. Dental whitening agents have been getting popular in the last few years, as everyone wishes to have a bright and pleasing smile.
