By making your teeth appear whiter and brighter, tooth whitening is a cosmetic procedure that can enhance the appearance of your smile. There are several ways to whiten teeth, including in-office bleaching, trays, whitening toothpastes, gels, and strips. Carbamide peroxide and hydrogen peroxide, which can lighten the colour of your teeth by dissolving stains on the enamel, are the most common ingredients in whitening products. 

For those who wish to get rid of yellow or brown discoloration brought on by food, beverages, tobacco use, or ageing, tooth whitening is the best option available for those with healthy, unrestored teeth and gums. Tooth whitening is not advised for everyone, though. Some people may get uneven results from whitening products, gum irritation, or tooth sensitivity.
