Teeth Whitening

Teeth whitening or tooth bleaching is the most popular cosmetic dentistry procedure because it can significantly improve the appearance of teeth at much less cost than other techniques such as porcelain veneers or tooth bonding. The process of bleaching your teeth can truly improve the appearance of your teeth.

Why we need Teeth Whitening

Human teeth naturally vary in color. Not all people are lucky to have a bright white as the natural color of their teeth. Many persons have slightly yellow teeth by nature.

Stained teeth is a very common dental problem that makes a lot of people to feel uncomfortable when they have to talk or smile, due to the color of their teeth. Stained or discolored teeth are caused by many different reasons but the acquisition of colored substances onto the tooth pellicle is the main reason that makes teeth to lose their natural white color.

Regular tooth brushing can only remove some of the extrinsic stains from the outer surface of the tooth enamel. Only ‘teeth bleaching’ can actually whiten teeth removing deep intrinsic stains and lightening their color. The procedure can be done in the dental office or at home.

How does Teeth Whitening work?

Professional whitening of your teeth is achieved using oxidising agents such as carbamide peroxide or hydrogen peroxide. These agents teeth and gradually bleach them over time. The oxidising agents penetrate the enamel and bleach the dentine. The degree of color change that occurs during bleaching depends on the types of stains present, the peroxide dose, the amount of time on the teeth and how frequently it is performed.

Advances in modern cosmetic dentistry have made available a wide variety of treatment options for people who are unhappy with their smile. Teeth Whitening methods used will vary in effectiveness, cost, durability, and side effects.

Before you start Teeth Whitening

A dental examination is necessary to help determine if the patient is a good candidate for bleaching and what treatments are best. This examination will include a dental history focusing on the factors that may have caused the stains. People with gum disease and worn tooth enamel, and pregnant women are not good candidates. Some areas, including artificial crowns, veneers and the roots of the teeth, cannot be whitened by bleaching.

Teeth Whitening methods
