Getting rid of the "dark past"
There are three primary colors of enamel (yellow, yellowish-white, and blue and white) and a lot of shades. However, even the whitest teeth by nature, alas, are not immune from the changes caused by many reasons. Darkening of the teeth can be superficial and internal. On the surface, darkening on the tooth affected by smoking, frequent consumption of coffee, tea, red wine, dark juice, as well as some products - such as blueberries, coloring itself as enamel, and it accumulates in the tartar. Teeth look dull and give the impression of clean enough. However, no matter how unpleasant superficial contamination did not appear, they succumb to remove easily, efficiently and for a long time.
Internal staining of teeth is less common and requires a more serious intervention. Spots in the "body" of the tooth can be triggered by the use of dyes during the formation of tooth enamel, use of prenatal development (approximately 4 months of pregnancy the mother) or early childhood (0-7 years), tetracyclines, an excess of fluoride in the body, and and age-related changes that cause "wear" enamel. However, for such problems, in most cases you can find a bleaching solution, only the procedures take more time and effort than a superficial staining, and require more advanced dental technology and a highly skilled medical care.
Today dentists offer several ways to professional (it is also called the office) teeth whitening. Almost all of them are based on the oxidation of hydrogen peroxide solution tridtsatipyatiprotsentnogo, which accelerates the action of heat or irradiation.

Unfortunately, there is no odoznachnyh medical research data showing that laser whitening in the long run strengthens enamel, because the procedure is still relatively young, but the harm it definitely does not work.
