The Magic of Teeth Whitening

The changing of the color of the teeth indicates aging. Most old people have noticeably darker teeth compared with young adults simply because their teeth have been exposed to a lot of pigmented substances after many years of eating and drinking. However, there are cases of discoloration that are not associated with the advancement of age. It can be caused by congenital factors or by some medications.

Some people are born with discolored teeth. Unlike most people whose teeth in their childhood are deciduous white, they have yellowish to dark brown teeth as early as their emergence. Others acquired discoloration from excessive smoking. Studies show that tobacco produces a kind of stain that is very hard to remove as it calcifies on the surface of the teeth. There are also cases when the color of the teeth changes because of the intake of certain drugs like tetracycline.

Discolored teeth are an embarrassment for many people. They think that upon losing the attractive appearance of the teeth, which they consider as the soul of their smile, they will also lose the chance of gaining more friends and opportunities in life. Fortunately, there is no difficult dental imperfection that cosmetic dentistry cannot resolve. Skilled cosmetic dentists in progressive cities like Las Vegas perform teeth whitening and bleaching procedures.

Teeth whitening or bleaching is a cosmetic dentistry procedure aimed at bringing back the deciduous whiteness of the teeth or decreasing the natural dark color of the teeth. There are several methods that a dentist Las Vegas has can perform depending on the level of discoloration being dealt with. The most common is the application of oxidizing agents to remove the interprismatic stains stuck on the micro-cracks on the teeth.

The teeth acquire micro-cracks from continuous grinding. The pressure, which is not strong enough to crack an entire tooth, results in microscopic changes on the surface of the teeth. The cracks formed become canals that collect the stains until they change the color of the teeth over time. A dentist Las Vegas has to offer uses hydrogen peroxide or carbamide peroxide to extract them.

Even though the stains are removed, the micro-cracks are still present and able to contain stains in the long run. This is the reason why a dentist Las Vegas has to offer recommends a teeth whitening appointment every three months to maintain the desirable whiteness of the teeth. In some cases, a lack of maintenance results to an even darker color of the teeth.
