Why do teeth darken?

Often, people think that their teeth are dark or have acquired a yellowish tint, while in fact it is not so.Constant exposure to advertisements and modern standards of beauty contradict the laws of natural harmony.Everyone has its own unique color, eyes, hair and teeth.According to statistics, only 5% of people have a light shade of white teeth, which means that 95% are yellowish or grayish, and this is perfectly normal.

Affect the color of the teeth can be frequently used foods, especially coffee, black tea, chocolate, red wine.

Plaque, especially the so-called "raid smoker", also gives

the teeth a darker shade.

Occasionally tooth discoloration is congenital in nature and involves the use of antibiotics (especially tetracycline) the mother during pregnancy.

In some cases, the tooth darkens after trauma or root canal filling, especially the so-called resorcinol-formalin method.

to elaborate on the methods of teeth whitening enamel, ie estesstvenno lightening the color of teeth by several shades.Depending on the purpose and the means used are the following methods of teeth whitening:

• Bleaching living teeth
- Home bleaching
Teeth - Teeth whitening
- Combined whitening
teeth • Whitening "dead»
teeth • enamel Mikroobraziya

whitening living teeth

The basis of this bleaching method is the penetration of the bleaching agent through the enamel to the dentine change in color of the tooth.Such an agent is generally a carbamide peroxide in different concentrations.

Home bleaching is recommended, if the change is not excessive in nature color.The concentration of the bleaching agent in this case is 10 times lower than for a professional bleaching.In any case, home whitening is carried out under the supervision of a physician.

patient begins to notice results within 2-3 days, completely bleaching process is completed in 3-6 weeks.The result usually is quite resistant (up to several years), but 1-2 times a year is recommended to support the course.

How is the home teeth whitening?

Some sets for the home teeth whitening already include standard mouthguard, but still it will be much safer and more convenient if an individual mouthguard will make you a doctor.To do this, remove the casts of both jaws and make their models, which are made in the future and individual silicone splints.To begin the whitening process it is necessary to fill the mouthguard 1 \ 3 bleaching agent and to fix on previously cleaned teeth.

first mouthguard should be worn no more than an hour, gradually increasing the duration of 7-10 hours.Day or night mode teeth whitening a patient chooses, depending on your daily routine.

To reduce the effects of increased tooth sensitivity after bleaching is recommended to alternate the application of whitening gel with fluoride (as a rule, it is also included in the kit for home bleaching).To avoid irritation of the gums, when every time you put on the form of whitening, remove (toothbrush or finger), speaking on its edges once the gel, so it does not hit on the gums.

Thus, the patient himself carries teeth whitening procedure, the physician only controls it monitors the absence of complications.

home whitening procedure is extremely safe in compliance with all recommendations, moreover, it is quite affordable (from 500-700 rubles and above).The disadvantage of this procedure is the duration of its implementation.

If there are minimal side effects such as increasing the sensitivity of the teeth, gum irritation, tooth pain - the doctor is usually recommended to reduce the daily time wearing molds for teeth whitening, or even wear it the next day.Since in both cases the gel time and contact tissues of the mouth of the patient is reduced, side effects usually disappear.In more serious cases (headaches, bleeding gums, allergic reactions), a dentist can prescribe treatment;in some cases the process of teeth whitening is recommended to stop.

Professional teeth whitening

Professional tooth whitening has a more intense effect on the tooth tissue due to the higher concentration of peroxide bleaching agents in the composition.This method of teeth whitening is used for significant changes in tooth color, it gives a quick result.Since getting a concentrated gel in the oral mucosa may cause a burn, then this type of whitening is performed by a doctor in a dental office.

whitening teeth whitening procedure entails some undesirable consequences.

One of the problems may become too white teeth after the procedure, which will turn from the natural color of artificial teeth.

The second problem is more significant.We are talking about increasing the sensitivity of the teeth, which may occur for 2-3 days even after the first session of teeth whitening in the dental clinic.Even more danger of increasing the sensitivity of tooth enamel in the secondary the procedure.

should also be remembered that in most cases, a yellowish color of tooth enamel, which are so eager to get rid of the patients is the natural color of teeth, and the yellowish enamel is considered the most durable enamel.When you attempt a long-term, "deep", lighten the enamel loses some of its properties, and among them - strength.Therefore, even if the tooth enamel to remain intact and will not get cracks, its quality becomes worse.

main problem of teeth whitening is connected with the existing dental fillings.It consists in the fact that in the process of whitening gels are unable to change their color as well as they change color enamel kind - that is, the seal will be updated to match the color of the color of bleached teeth.

whitening folk remedies in

home Until now, many patients, despite the possibility of professional whitening, prefer national methods.Perhaps, the first place is occupied by soda.For teeth whitening applies a highly concentrated solution of it, or it is simply added to toothpaste.The effectiveness of this method is controversial enough, but the frequent use can lead to abrasion of enamel and, as a consequence, increased tooth sensitivity.Soda - a very coarse abrasive, it mechanically cleans surface contamination, which causes its whitening effect.

Also in coarse abrasives such as using activated carbon and ash.Effect otih use very unstable and undesirable consequences and can be a cause for treatment to the dentist.
