Perfect white teeth are definitely beautiful. Previously, the bleaching procedure was very expensive and therefore affordable only to well-off citizens. Now the cost of this service has decreased slightly, safer methods have appeared, therefore people with bleached teeth are more and more common. In the network, the bleaching procedure is positioned as absolutely safe. However, one should not have illusions: in order to get a snow-white smile for the envy of everyone, one will have to sacrifice quite a lot. And whitening is not so safe for our health, as people who advertise dental clinics try to present.
Caution: hydrogen peroxide!
A number of studies have shown that the harm from bleaching, although not explicit, does exist. Specialists from Volgograd Medical University conducted a survey of patients in dental clinics (30 people) and 8 of them expressed dissatisfaction with the results and expectations – there were facts of general malaise and the development of diseases such as caries.
Different types of whitening, their pros and cons are described in the book “Teeth whitening. Therapeutic Dentistry “, written by specialists of the highest category Natalia Mukhina and Peter Skripnikov. You can also get information on this issue from Leonid Denisov ‘s work “Modern means and methods of teeth whitening”, which is included in the collection “Modern dentistry” (2002). These and other authors certainly admit that the latest bleaching techniques are much safer than those used by dentists before. However, they still have their drawbacks.
According to the research of scientists J. Mac Kraken and M. Cooper, the use of various gels for teeth whitening entails changes in dentin, as well as a significantly pronounced manifestation of the sensitivity of the pulp. This is the result of the rapid penetration of the whitening material into the dentin itself and changes in its structure. Changes in the structure entail micro-destruction, which cannot be immediately replaced. This is a direct way for infections, even in the absence of caries or similar problems.
The use of a whitening gel with carbamide peroxide results in a slight decrease in the hardness of the enamel. J. Mac Kraken proved a direct link between the bleaching procedure and the condition of the enamel in terms of its durability. The use of the above composition is not the best way affects the state Local reactions to carbamide peroxide can be added to this, so modern cosmetic dentistry is gradually refusing to use such formulations in favor of less harmful ones.
A specialist of the Central Research Institute of Dentistry A. Lyashchenko using flowmetry found that almost half of the patients after bleaching reduced the blood flow in the pulp by about 30-80%, and for quite a long time. Over time, the blood flow is restored, but the problem exists in terms of impaired blood saturation of individual jaw structures, which can lead to the appearance of problem areas in the future.
The problem is that one-time whitening is not a panacea. It does not work for life. The procedure has to be repeated periodically. This means that the teeth are again and again exposed to a damaging effect. Enamel gradually becomes thinner, which leads to increased sensitivity of teeth. A person with sensitive teeth cannot normally eat. Hot, cold, too sweet or delicacies containing fruit acids cause pain. It has a bad effect on the mental state: nervousness increases, headaches become more frequent, even sleep suffers.
In addition to chemical reagents, abrasives are also used to whiten tooth enamel. They contain very small solid particles acting on the surface of the tooth as a scrub. An example of such means is in many in the bathroom. These are whitening toothpastes with hard microparticles. In professional dentistry, such substances are used only as a last resort if there is no other way out (the patient does not have enough money for more benign techniques or her teeth are so neglected that neither photobleaching nor other methods help). The client is warned that substances with abrasive particles severely damage the enamel. However, they not only thin the hard tissue of the tooth, but also damage the gums. Particularly affected by lovers of whitening pastes, which include abrasive granules. Fans of whiteness often face the phenomenon of bleeding gums. This is not only an aesthetic, but also a therapeutic problem. A damaged gum, from which blood is periodically drawn, is an open gate for infection. There is a lot of breeding ground for bacteria in a person’s mouth. On the teeth, tongue and gums constantly lives a whole “menagerie” – about 700 species of microorganisms of various degrees of danger. These are streptococci, Prevotella, Lactobacilli, etc. 30–60% of all this “beauty” is Streptococcus. If a person is fine with immunity and there is no damage to the mucous membrane, then the bacteria do not pose a threat to health. But if the gums bleed, streptococci enter the internal environment and are distributed by blood to all organs. The consequences of such an impact can be very unpredictable: from frequent colds due to constant stress on the immune system – to stomach ulcers and other serious diseases. So it is necessary to use bleaching pastes extremely moderately and only after consulting with a dentist.
Another problem is the care of teeth already whitened. The main recommendation of doctors is that the patient should minimize the consumption of such coloring drinks as fruit juices, red wines, black tea, and coffee. You can not smoke, eat berries, intensely colored fruits and nuts. If everything is more or less clear with smoking and alcohol, well, it’s impossible, it’s impossible, it’s very unhealthy to limit yourself in berries, fruit juices and nuts. The diet is depleted in vitamins, and they are in short supply in some regions of Russia. It turns out that white teeth become the cause of poor nutrition, which is devoid of many useful substances. What is fraught with beriberi, many people know. Lack of vitamins and microelements – is exfoliated nails, dry and brittle hair, unhealthy complexion, chronic fatigue, blurred vision and problems with many other organs. So one beauty procedure leads to problems throughout the body.
