People often forget that taking care of their teeth, and oral hygiene in general, is just as important to your regular health as your diet, your exercise, your sleep, and every other aspect of your general health. But too often we forget that regular brushing, flossing, and trips to our dentists are just as necessary as check-ups with your family physician. While the American Dental Association might not care if you're eating enough fruit or vegetables, you should certainly be aware that improper oral care can lead you beyond your regular dentist's chair, and into the attending care of cosmetic dentists.
I don't mean to put a scare into you beyond your regular normal fears of dentists, as cosmetic dentists are specialized professionals who can fix your smiles like nobody else's business. The tricky thing is when it becomes necessary to visit a cosmetic dentist, you want to be able to find the right one, not just the one with the best smile--because he probably had someone else do it for him!

Teeth Whitening
|
|
Teeth whitening, also called tooth bleaching, is a common procedure in general dentistry but most especially in the field of cosmetic dentistry. Many people consider white teeth to be an attractive feature of a smile. A child's deciduous teeth are generally whiter than the adult teeth that follow. As a person ages the adult teeth often become darker. This darkening is due to changes in the mineral structure of the tooth, as the enamel becomes less porous. Teeth can also become stained by bacterial pigments, foodstuffs and tobacco.
As white teeth are subconsciously associated with youth, they have become desirable. This has been made more apparent with the spread of American culture worldwide[1], where an especially white smile is coined a "Hollywood smile". The procedure to bleach teeth uses oxidizing agents such as hydrogen peroxide or carbamide peroxide to lighten the shade of the tooth. The oxidizing agent penetrates the porosities in the rod-like crystal structure of enamel and oxidizes interprismatic stain deposits; over a period of time, the dentin layer, lying underneath the enamel, is also bleached. Tooth bleaching will generally last from 5 to 7 years, with variations from factors such as cigarette smoking, and tea and coffee consumption. |
