Why Teeth Whitening?

Most of us often have sparkling white teeth in the beginning, but over time the porcelain-like enamel surface is stained.  The enamel is composed of crystalline rods designed to facilitate gnashing, but trauma and acids drawn from sugars make it wear down.  As years go by, the enamel is worn down, becomes more transparent thus allowing the dentin's yellow color to get exposed.

Teeth whitening gets rid of the stains and debris, this leaves the enamel open and susceptible to periodic wear and tear as you use your teeth on a daily basis.  Teeth discoloration is caused by two types of stains: extrinsic stains-that manifest on the surface of teeth due to beverages and foods with dark colors as well as tobacco; and intrinsic stains that form from the inner section of teeth.  They often result from continuous trauma, aging, and exposure to minerals and excessive fluoride in meals and drinks.

Teenagers are more likely to experience remarkable results from bleaching. By the twenties teeth whitening will yield better results, but by the forties whitening may require more effort. By the late fifties, the teeth will have gathered all the stubborn stains that are difficult to remove but with extra effort it can be achieved.

Starting colour

Additionally, acidic foods contribute to periodic enamel erosion, especially citrus fruits and vinegar, which expose the dentin's yellow color in the enamel.
