Tooth bleaching, also known as tooth whitening, 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 increase in value--that is to say, they 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.<br> <br> http://www.naturalelements.co.uk/teeth-whitening-index/ http://blogs.law.harvard.edu/tech/rss Mon, 20 Aug 2007 10:14:03 +0100 Mon, 20 Aug 2007 10:13:30 +0100 FeedForAll v1.0 (1.0.2.0) Beauty products do not just include colorful lipsticks and shiny nail polish.

Many people are too embarrassed to show their teeth in public as they are not as white as they would like them to be! http://www.naturalelements.co.uk/article/teeth-whitening/whiter-teeth/ Tue, 16 Jan 2007 17:17:59 +0100 Darkening of the teeth may be caused by medications that you have been prescribed, stains (tobacco, caffeine, some juices, etc), or aging. As we age, the enamel of our teeth wears away, revealing the darker, inner portion of the tooth. http://www.naturalelements.co.uk/article/teeth-whitening/treatments/ Tue, 9 Jan 2007 14:24:27 +0100
