Also known as TOOTH WHITENING ,is a common procedure in general dentistry  & more specifically in cosmetic dentistry.

Why Bleaching?

Child’s milk teeth are generally whiter than the adult teeth that follow.As a person ages adult teeth often become darker due to changes in mineral structureof tooth as enamel becomes more porus.Tooth staining can be-

Extrinsic(outer)-

Mainly due to bacterial pigments,food stuffs like-tea ,coffee ,red wine & aerated drinks,and tobacoo products like-cigrattes ,pan masala, cigars etc.

INTRINSIC(internal)-

These are the stains incorporated vin the deeper layer of tooth structure.

Certain antibiotics like tetracycline can lead to teeth stains and due to to high level of fluoride in drinking water during tooth formative years can lead to brown staining of teeth known as FLUORISIS.

AGEING DISCOLORATION-

Due to ageing there is reduction in brilliance of enamel causing teeth to appear more yellow.

IN OFFICE BLEACH-

This is most effective metod,performed by the dentist by applying a high concentration of bleaching agent on teeth & activating it by bleaching light.the oxidising agent penetrates the crystal structure of enamel to oxidise the stains .the underlying layer of dentin is also bleached.

The procedure can be done in approximately 1hr. in a single visit to dentist’s office.

This procedure is followed by application of fluoride gel on bleached tooth surface.

          A typical course of bleaching  can produce dramatic improvements in cosmetic appearance of most stained teeth,however some stains do not respond tobleaching and can only be taken care of by veneering or crowning.Your dentist is the best judge to decide about the procedure best suited for you.
