Always seek white teeth for an attractive look. This can be achieved through tooth whitening, which helps eliminate teeth discoloration and restore a bright smile, but bleaching does not suit some people like pregnant women and lactating women.
German dentist Dittmar Ostrich said teeth whitening did not match some teeth. "Doctors should clarify some things for patients," he said. "It's only possible to bleach some teeth, not dentures or toothpicks."
In addition, teeth whitening may become more expensive than planned, as the doctor may have to renew crowns or fillings, because they may be in different colors.
Wolfgang Boer, spokesman for the German Society of Cosmetic Dentistry, added that dental whitening is not cheap, purely cosmetic and has no medical reasons.
Check the teeth first
"Before bleaching, teeth should be examined. The dentist knows whether or not teeth can be whitened. For example, in some cases tooth decay is due to falls or shocks. Bleeding causes age," said Ostrich. Looks dark. "
In addition, the treatment of the roots may make the tooth look dark, and in such cases does not change the regular whitening of the shape of the outer tooth, and such teeth need to whitening processes from the inside in the dentist clinic only.
Therefore, medical examination is very important before bleaching, since the patient can not determine for himself whether the coloration of the tooth is due to calcareous deposits accumulated over the age or because of the color inside the tooth.
In addition, physicians are advised to perform a professional dental cleaning before each whitening process, so that the teeth look brighter and are less expensive.
Dental health and gums
Wolfgang Isser, of the German Dental Association, explained that tooth and gum health is a basic requirement for bleaching. It is not appropriate to bleach when tooth decay, lack of fillings, tooth decay or tooth fractures. , In such cases the substance may leak into the tooth, causing the emergence of pain or damage to the teeth and nerves.
"The teeth of teenagers are very dangerous because of nerve damage, because the structure of the teeth is not yet complete," Acer said.
In addition, pregnant and lactating women and people who do not have bleaching ingredients should abandon tooth whitening.
Two ways to bleach
Ostraich pointed out that there are two ways to whiten the teeth mainly, namely:
1 - bleaching in dental clinics, as the process of bleaching by dentists.
2 - Bleach at home, where a splint teeth first in the clinic, and used in the home with the bleach provided by the dentist, but this method requires that the dentist explain to the patient at the beginning, and to verify them later.
Bleaching results do not last forever. Bleaching may last for three to five years, but this is closely related to eating habits and tooth cleaning. For example, bleaching is quickly eliminated in case of smoking or lack of interest in cleaning teeth.
Single side effect
Doctors do not see any danger from bleaching. "When bleaching correctly, the only side effect is to increase the sensitivity of the teeth to cold and hot objects, but this effect often disappears after a few hours or Lasts for two or three days. "
Doctors say teeth whitening can remove surface coloring, caused by coffee, tea or nicotine, better than traditional toothpaste, but teeth do not always look bright.
In general, one has to deal with teeth whitening names carefully, because they contain abrasive materials that are more rough than ordinary pastes and chemical additives, and therefore not only remove sediment, but can damage tooth enamel.
