Teeth whitening is a cosmetic dental treatment designed to lighten the color of teeth and enhance their overall appearance. The treatment involves the application of a whitening agent, typically containing hydrogen peroxide or carbamide peroxide, to the tooth surfaces. This agent penetrates the enamel and breaks down stains or discolorations. The process can be performed in a dental office under professional supervision or at home using dentist-prescribed kits. In-office treatments often use specialized light or laser technology to accelerate the whitening process. Teeth whitening is a non-invasive and popular option for addressing extrinsic stains caused by factors like aging, consumption of certain foods, or smoking. However, it may not be suitable for intrinsic stains related to factors like dental trauma or medication use. Regular maintenance is often recommended to prolong the whitening effects.
