Bleaching

Dental bleaching is a common procedure in general dentistry.  Bleaching whitens beyond the natural Teeth whitening has become the most requested procedure in cosmetic dentistry today. 

Everybody loves a bright white smile. If you would like to bleach your teeth, start by speaking with your dentist. He can tell you whether bleaching procedures would be effective for you. Whiteners may not correct all types of discoloration. 

For example:

Yellowish teeth will probably bleach well Brownish-colored teeth may bleach less well Grayish teeth may not bleach well at all Bonding or tooth-colored fillings placed in your teeth will not change in color and they will stand out 

Bleaching methods use carbamide peroxide which reacts with water to form hydrogen peroxide. Carbamide peroxide has about a third of the strength of hydrogen peroxide. The peroxide oxidizing agent penetrates the porosities in the rod-like crystal structure of enamel and breaks down stain deposits in the dentin. 

Methods 

In-office bleaching:  This bleaching method is performed at the dental office and usually requires only one office visit. The dentist will apply a protective gel to your gums to protect the oral soft tissues. A bleaching agent is then applied to the teeth. 

At-home bleaching: Peroxide-containing whiteners actually bleach the tooth enamel. They typically come in a gel and are placed in a mouth guard. Usage regimens vary. 

Risks of teeth bleaching include, but are not limited to:

Chemical burns from gel bleaching on the gingiva Overbleaching (bleached effect), particularly with the intensive treatments Pain for "sensitive teeth" caused by open dentinal tubules. Risk of increased hot/cold sensitivity. Risk of bleachorexia (an unhealthy obsession with whitening one's teeth)
