Bleaching
Tooth bleaching is the most common procedure in cosmetic dentistry. Bleaching of teeth is one of the most conservative and cost-effective dental treatments for discoloured teeth than aggressive methods like veneering, crowning or bonding to enhance an individual smile.
It is ideal for people who have healthy and unrestored teeth and gums. Tooth whitening cannot make a complete colour change but it may lighten the existing shade and is not permanent.
Currently, bleaching agents which are used are based primarily on either hydrogen peroxide or carbamide peroxide. The peroxide oxidizing agent penetrates the porosities in the rod-like crystal structure of enamel and breaks down the stain.
Yellowish teeth respond well to bleaching compared to brownish-coloured teeth. Gray/purple or tetracycline stains are more difficult to lighten and may require prolonged bleaching. The effect is less likely to last as long if you smoke, eat or drink products that stain your teeth.
Teeth can turn yellow or become discoloured for a number of different reasons. Though age is a significant reason - smoking, certain foods, coffee, tea, antibiotics, etc, can also cause teeth to turn yellow.
