Snow white smile recently became an indicator of health, beauty and respectability. To a greater extent, thanks to the Hollywood standards of beauty, it's not for nothing that they say - a Hollywood smile.
Maybe in Hollywood the atmosphere itself has a dazzling radiance (although most of the work of dentists), but do not forget that tooth enamel is rarely white from nature. Rather, not enamel, but the tissue of dentin, which is under the enamel and contains a pigment.
As dentists say, the snow-white color of teeth is only among representatives of the Negroid race. For the rest of humanity, teeth can be yellowish, pink, brown and gray. Not very aesthetic by today's standards, is not it?.
Why it happens and it is possible to fix it without harm to health - let's try to understand.
The following factors can lead to a change in the white color of the teeth:.
- external staining: pigmented deposits on the surfaces of hard tooth tissues, tartar. Staining occurs when smoking, with the use of some "colored" fruits, vegetables, red wine, soy sauce, colored carbonated drinks, coffee, tea (especially cold).
- internal staining: pigmentation of hard tissues. Occurs in endodontic treatment (treatment of root canals, depulpation), in violation of the formation of teeth (inadequate maturation of dentin or enamel) and with the use of certain drugs in early childhood.
Depending on these reasons, the dentist recommends the bleaching method:.
- mechanical removal of tartar and pigment;.
- chemical effects;.
- masking of pigmented areas (installation of veneers).
It is worth noting that the mechanical removal of scales by ultrasound (scaling) can help solve the problem in very many cases: the teeth look much better. In addition, this procedure refers to the recommended every six months by all dentists professional hygiene of the oral cavity and must anticipate further bleaching (if required).
The now popular Air Flow procedure combines both mechanical and chemical effects and consists in polishing teeth with an air-soda mixture fed under pressure. One of the negative aspects of this method is the presence of soda - a known abrasive, and it, as is known, can damage enamel.
In chemical whitening, all modern bleaching systems include the action of various concentrations of hydrogen peroxide (bleaching using self-, light- or heat-activated gels containing 20-37% hydrogen peroxide).
It can be combined (or rather, in most cases should be combined) with the previous treatment of enamel with protective varnishes and gels. For example, the ZOOM system. The meaning of bleaching is that a special gel is applied to the teeth containing all the same hydrogen peroxide from which active oxygen is released under the action of ultraviolet, affecting enamel and dentin. At the same time, tooth sensitivity is very often increased.
