Generally speaking, all methods of teeth whitening can be divided into two large groups: professional and home. The latter today have become very popular as few people like the extra time to go to the dentist, even if he is not going to get anything to drill and, especially, "to tear out".
However, before you begin your journey to a snow-white smile, it is helpful first to understand – and what today are the types of teeth whitening than they fundamentally differ and which one is most effective. In addition, in the pursuit of efficiency we should not forget that many types of teeth whitening have a very negative impact on the state of tooth enamel – it is also necessary to know in advance.
Methods of teeth whitening is essentially divided into chemical and mechanical.
Chemical whitening is the process of destruction of colored organic compounds within the enamel with the help of special substances.
Mechanical whitening is, in fact, professional oral hygiene, which many dentists and whitening do not believe (although the procedure gives a very distinct visual effect).
Mechanical whitening of the teeth: the principle of
Mechanical teeth whitening is a method of clarification in which the removable dental deposits (stones, plaque), which leads eventually to the return of the natural color of the teeth.
Often those people who over the years have grown on the teeth "plaque smoker", coffee lover, and conglomerates rocks (mostly on the lower front teeth) for a long time already forgot how normal should look like their teeth are clean. But in such cases you need to look for peroxide-containing pencils or strips to whiten your teeth, but to focus primarily on carrying out professional hygiene of the oral cavity – this will give a much greater effect.
An important property of the mechanical whitening is relative safety for the tooth enamel, because the main impact is not on the enamel, and deposits located on its surface.
Often, however, there are cases when after carrying out the relevant procedure may appear quite unpleasant consequences. Due to the fact that the removal of dental calculus and plaque is often conducted on the background of periodontal disease (e.g. periodontitis), after the procedure the teeth are actually unprotected. Prior to this, from all kinds of stimuli they saved the stones, and after removal of the neck of the teeth react with pain to cold, hot, etc. (this is confirmed by the numerous reviews online).
This problem is solved most often by a dentist-periodontist who is treating the underlying disease and simultaneously provides deep fluoridation of enamel and hypersensitivity (in some cases) root cement.
When do you want teeth whitening, and when it's redundant?
As practice shows, out of 10 people turning to the dentist for a teeth whitening procedure, only about 6-7 of them it will be really appropriate, but for the rest will be either ineffective (because the enamel is already close to the natural shade) or extremely unsafe.
The instances in which bleaching will be effective:
- The presence of plaque and dental deposits;
- Change shades of enamel in connection with age;
- Acquired staining of the hard tissues of the tooth in a yellow or brown color.
Difficult to bleaching:
- A congenital discoloration of enamel ;
- The gray coloration;
- Change the color of dentin.
Staining on the background plaque and Tartar buildup is eliminated mechanical types of bleaching, and the "internal" chemical.
Mechanical teeth whitening allows ultrasound to remove plaque from all surfaces of teeth using ultrasonic devices and scalers. In addition, ultrasonic whitening allows you to clear the so-called "smoker's plaque", which is neither domestic nor professional brushes to remove is almost impossible.
Due to the ultrasonic vibrations at the end of the special handpiece is a mechanical destruction of the structure of dental plaque and stone, and its removal from the enamel surface. In accordance with the basic instructions, professional oral hygiene with ultrasound the enamel is not injured, and the negative effects from this type of whitening usually does not occur.
When performing ultrasonic cleaning of the teeth through the tip of the tooth is supplied with water: this is necessary to ensure the safety and efficiency of the procedure. Water helps to prevent overheating of the tooth (this would lead to necrosis of the pulp), and also creates a vortex flow due to the oscillatory motion of the tip, which improves the detachment of Tartar and plaque.
The technology Air-Flow is a mechanical effect on the object (the tooth surface) are released under high pressure jets of air, water and ordinary baking soda. Thus, inside the unit Air-Flow is the powder of sodium bicarbonate (ordinary baking soda, which in this case is used as an abrasive) and water-to-air channels.
Additional mechanical ways enamel brightening
Mechanical home methods of teeth whitening are perhaps the most popular among the population today, but at the same time – not the most reliable and often even dangerous to the health of the teeth.
Most often, in order to make teeth whiter, people are trying to apply the so-called whitening toothpastes. This is due to the fact that is very attractive this idea – clean his teeth, and every day they are becoming whiter and whiter...
However, many do not even think that as an active component in most of these pastes introduce abrasive powders that are really actively clean off plaque, but in the process also can seriously disrupt the structure of the enamel (simply gradually this enamel wash).
From the analysis of the results of research whitening toothpastes, and even just reading the reviews of ordinary people, it can be concluded that whitening toothpastes on the basis of the abrasives can help deal with soft and even hard plaque, but over time can also spoil the tooth enamel.
Whitening toothpastes on the basis of chemical substances (e.g. enzymes) do not affect a dense plaque with the force, as it requires a real whitening, and therefore the result of their application is questionable. However, there are many defenders of this type of pasta, which mark the whitening effect (but it doesn't account for the fact that manufacturers often add abrasive substances to help people cope with plaque using the normal "friction", and the presence of various Exotica in the recipe of the paste is in this case nothing more than a marketing ploy).
Chemical bleaching different systems: pros and cons
Chemical teeth whitening existing popular systems can be divided into professional and home. Professional whitening has a good whitening effect due to high concentrations of hydrogen peroxide or its derivatives, which are active components deposited on the surface of the tooth gels.
Modern technologies of chemical teeth whitening involve the use of activators that initiate the breakdown of peroxide with active oxygen emission. It can be:
- Ultraviolet radiation;
- Laser radiation.
Chemical than professional teeth whitening different from home?
First, the concentration of bleaching agents for the types of professional whitening is significantly higher (usually 30-35%). "Home" the concentration of 10-15%. This is due to the fact that the dentist's office there are more options to protect gums and oral mucosa from aggressive substances.
Second, the real result of professional whitening, you can get a much faster (usually in one visit) and home methods can take up to 2 weeks or more.
Thirdly, the types of professional bleaching often involve additional activation of the chemical reaction apparatus based on laser, ultraviolet radiation, etc. – to achieve the most pronounced, fast and safe effect.
The main advantage is the reduced harm to the enamel (compared to a professional whitening), and minus – slight indicators of whitening.
Homemade methods of chemical bleaching
In addition to the controlled home teeth whitening with customized whitening systems there are also "Amateur" options for the implementation of such procedures are: bleaching strips, pencils, etc.
The appliance tooth whitening: advantages and disadvantages
Hardware teeth whitening technology Cabinet chemical bleaching, but with the activation process with ultraviolet light.
With cold whitening gel based on hydrogen peroxide applied to the tooth surface is activated by ultraviolet, halogen or led lamp. The peroxide concentration is usually quite high, averaging 25-35%.
Hardware whitening is one of the most effective methods, as its technology specifically aimed at improving outcomes and reducing tooth sensitivity . The light allows you to:
- to increase the rate of decomposition of peroxide compounds with active oxygen emission (which, in fact, plays a key role in bleaching colored substances);
- allows to reduce the exposure time of the gel, which in turn reduces the negative effects on the enamel.
Laser teeth whitening
Laser teeth whitening is a modern and quite effective method of lightening, practiced for about 15 years. Numerous studies have shown that in most clinical cases it is really effective and relatively safe.
The principle of laser whitening is almost the same as when a hardware method of whitening: in the teeth to apply the whitening composition based on hydrogen peroxide, however, the activation of the active substance is not ultraviolet lamps, and laser. Laser is a kind of catalyst, not only affect the speed of chemical reactions, but also their depth (completeness).
Endo teeth whitening applies in the case that a dead tooth becomes a darker shade due to staining by substances formed when pulp necrosis, when the penetration of the pigment deep into the tissues of a dead tooth, or painting with a filling material.
In such cases, the external impact on the tooth is not possible to cope with the problem. But chemical bleaching allows to solve this problem, as evidenced by numerous positive reviews.
Traditional methods of teeth whitening: the harm or benefit?
Is it possible to undertake teeth whitening at home without the use of all these pencils, cap and whitening strips? Well, popular ways to whiten teeth have long been known, but their comparison with professional systems showed uncertain effectiveness and most importantly – insecurity (in some cases).
Controlled by a dentist home bleaching systems do not apply to traditional methods. Similarly, strips for whitening at home, trays, pencils and similar tools is developed by scientists system for home use, compared to old ways is not entirely safe, but more or less close to evidence-based medicine and often show some results.
From the history you can remember, charcoal was the most effective method of teeth whitening in Russia. However, currently, this whitening technology is hopelessly out of date (usually today try to whiten your teeth with activated charcoal which is sold in pharmacies in the form of tablets).
The idea of using activated charcoal for teeth whitening is based on widely known for its ability to absorb different compounds from solutions (a great absorbent).
However, it is foolish to hope that the charcoal will pull out of the enamel its coloring pigments. However, to wipe the plaque (including painted) activated charcoal is quite a force, though with the same success you can simply thoroughly clean the teeth toothpaste with medium abrasiveness.
Baking soda – whitens teeth, does she?
Baking soda is able to significantly increase pH in the mouth, neutralizing acids, but to whiten your teeth it at home will be very problematic.
Oddly enough, but strawberry is one of the most popular "berry-fruit" ways of whitening teeth, practiced in the people.
Offer a recipe of whitening something like this:
- Cut strawberries in half;
- Grind half the teeth;
- Leave for about 10 minutes;
- Then brush your teeth, usual toothpaste.
Count on a distinct whitening effect from such use of strawberries is clearly not worth it. However, organic acids contribute to the loosening of Tartar.
However, with the same success from long and regular action of organic acids will leach out the calcium from healthy enamel to cause caries in the stage of white spots in the smile zone, a problem which without treatment may be much greater than the benefit from such a dubious overall procedure.
