From time immemorial, the teeth are judged on the success andhuman appeal. Healthy teeth in a woman - is a healthy wife and healthy children. Strong teeth in a man - if anything, dig and have a snack or a tasty root zagryzet predator. Snow-white girl's smile - means aircraft being anything rougher than flower nectar, not use.
However, white and healthy teeth is not always considereda sign of beauty. Flip Flops and Japanese once stained teeth black. The colorant to the same terrible smell, which gave extra flavor to local beauties. In Pakistan, some nationalities nadpilivali front teeth and then chew some leaves: after this procedure sawed surface acquires a bright red color.
Among the exotic customs - drilled holesin canines and paste them into pebbles, flowers, rings and mirrors (that's where the "grow legs" modern skaylinga!). Saw through the grooves on the front teeth - the better to twist the rope from vegetable fibers, holding one end in his mouth. Sharpens the teeth with a file - hunter needed fangs, like a predator (by the way, in Ethiopia, in order to prove his "professional suitability" the young man had a bite is not too thin tree). And the crown of the tooth "design" - remove all of the teeth, and to sacrifice them to the gods.
Understand these symbols dentalconversion difficult. One thing is clear: in every culture and at all times without the "right" kinds of teeth - anywhere. Take the modern man: today want to look successful - 32 demonstrates flawless teeth. And if nature stinted on perfection, then please come to the dentist: correction of malocclusion, braces, dentures, or, at least, whitening.
The main methods of teeth whitening
Technology whitening today quite a lot. First you need to remember that technology is divided into domestic and professional.
Method 1. In the arsenal of home remedies include chewinggum, toothpaste (based on their actions - grinding principle, i.e. stains are removed from the surface of various solid particles), conditioners, gels and special systems. I must say that dentists are very skeptical about whitening toothpastes and chewing gum properties: the most that they can - to fight svezhepostupivshimi on the enamel surface of the pigments of coffee, tea, red wine, etc.
Method 2. More effective action and special gelssets: they are commonly used course of 3 days to a month. There is already operating principle - a chemical based on the ability of different compounds to react with plaque and pigments and destroy them; concentration of active substances - 10-15%.
Preparations applied to the regular cast of the teeth -mouthguard, which is worn for a night or a few hours in the afternoon. Some dental clinics can order individual mouthguard, ideally adjacent to the teeth and do not miss an irritating drug to the gums. However, due to a low concentration in the home sets the active ingredient results are modest and not very durable.
Such bleaching is performed in the clinicspecial equipment. And when selecting a particular method is to consult with a few dentists, so as not to fall for the "vparivanie" leading clinics for ways that you may not come.
Method 3. Those who have teeth white by nature, oftenit is enough to restore their natural color. For this fit based on the mechanical (abrasive) bleaching principle, for example, the system Air-Flow. By means of a special nozzle teeth cleaned pressurized cleaning powder mixture with water and compressed air. The bacteria, plaque, interdental deposits "deposits" pigment from tea and coffee, cigarettes disappear, revealing the natural whiteness of your own teeth.
Method 4. Gentle action on enamel renders bleachingultrasound. In addition to the above disadvantages, it also removes tartar. The final stage of this bleaching - teeth polishing pastes are treated, which will be a long time "to push" color pigments.
There is technology that combines the impact of water and ultrasonic: ultrasonic scaler. Thanks to its dual action, it can handle even the most dense and perennial deposits on the teeth.
Method 5. The most common and familiarprofessional teeth whitening methods can be called chemical whitening. The active ingredients used are the same as at home bleaching (carbamide peroxide, urea peroxide, hydrogen peroxide, chlorides), but their concentration is higher and, therefore, the result will be faster - for 1-2 half-hour session. The chemical method allows to whiten teeth deep enough and strong. There are options to use it, in which the impact on the teeth is limited to dental office, sometimes wearing the familiar mouthguard is expected at home.
The effect of chemical bleaching lasts from 2 to 5 years, then the procedure can be repeated.
An important condition for chemical teeth whiteningis the absence of visible surfaces of seals, composite materials, veneers, dentures, pins, etc. Foreign materials are completely different than the natural tissue, react with active chemical elements, and homogeneous bleaching will be difficult to achieve. Especially for such cases we invented laser whitening technology.
Method 6. Laser bleaching - less gentle, but moreeffective way to act, firstly, on the deeper tooth tissue, and secondly, as a spot. That is, a doctor works just as an artist by adjusting the degree of impact on each tooth portion.
Laser activates a specific chemical composition,applied to the enamel, and clearance is literally at the molecular level. This is the fastest way: for the hour session, you can whiten your teeth by 8-10 shades! But the most expensive compared to the rest, besides the oral cavity must be fully prepared: all seals in place, caries and periodontal disease are cured, no cracks and abrasions on the gums.
Process 7. In photobleaching catalystprocess appears halogen light. On the tooth is again applied to a special composition of which under the influence of light, oxygen, cracking down on the dark spots. A feature of the method is that it is suitable for sensitive teeth, tooth cracked and chipped, leaky seals and even bare roots - a "fire" way to put off a visit to the dentist. Minus - whitening turns too dazzling (effect of "porcelain" teeth), but this is not all there is. But with proper care the color can last a lifetime.
In advertisements dental clinicsalso come across the terms conservative and transformative whitening. First - this is the return of the natural tooth color, that is simply a thorough professional cleaning without affecting the structure of the teeth. Visually, these teeth look whiter and brighter. The second type of bleaching implies greater impact - mild abrasive to the surface of enamel or, in the case of photobleaching, the whole tooth as a whole.
And a little bit of security. Specific medical joke says that the greatest harm to the patient can apply himself and himself, the doctor's duty - to help him in this. Translated into "dental" it means: if you do not require the physician to make a smile Eddie Murphy all costs (under the motto: "I'm all paid"), even with the technology violation, time of exposure and, in spite of the decay, all whitening technology is absolutely harmless.
