Types of teeth whitening
To date, there are many dental techniques, each of which differs in the following parameters:
- composition and reagents used;
- frequency and number of procedures;
- whitening speed;
- degree of patient involvement.
For the procedures offered modern products, manufacturers of which promise with their help safe and high-quality whitening. Professional clarification is made on modern equipment and is in great demand.
Ways of dental office bleaching
With the help of professional cleaning of tooth enamel in the shortest possible time achieve excellent results and lasting effects. In this case, during the procedures, a sparing effect of tooth enamel occurs.
All dental office whitening are divided into several ways:
- mechanical;
- chemical;
- laser;
- ultrasonic;
- photo whitening
First of all, dentists recommend mechanical cleaning. If this method does not give the expected result, then the patient is offered other types of procedures.
Mechanical bleaching
The basis of dental mechanical cleaning lies professional oral hygiene. With this procedure, you can get a very pronounced visual effect, although dentists do not consider it as bleaching.
During the mechanical procedure, dental plaque and stones are removed. As a result, the natural color of tooth enamel returns to the patient. And if he has a white enamel by nature, then a Hollywood smile is guaranteed.
Many people who drink coffee, red wine, cola and smoke, look like their natural enamel, have forgotten for a long time. In these cases resort to chemicals, hydrogen peroxide, various pencils and stripes is impractical. First of all, you need to hold in the dental office oral hygiene.
With mechanical cleansing, the effect occurs on deposits that are on the surface of the teeth. That is why for enamel such a procedure is completely safe.
But there are cases when after dental removal of plaque and stones, the cervical area of the teeth is open. As a result, the teeth begin to react to hot and cold. Previously, they were saved from all these irritants by tartar. In this case, you should contact your periodontist, who will fluoridate the sensitive enamel and prescribe treatment.
Among the mechanical methods of clarification the most common is dental ultrasonic cleaning of teeth.
Ultrasonic whitening procedure
Using ultrasonic devices, both supragingival and subgingival stones are easily removed. Ultrasound allows you to clean even the tooth enamel smoker, with which neither professional brushes nor special toothpastes can handle.
How does ultrasound work?
At the end of a special tip due to ultrasonic vibrations, the destruction of plaque and stones occurs. Separated from enamel, they do not injure tissue. At the same time, the water that is necessary for the effectiveness and safety of the procedure gets onto the teeth through the handpiece. Water does not allow them to overheat and, due to the movements of the tip, creates vortex flows. With their help there is an improvement in the detachment of plaque and stones.
Air - Flow Technology
The technique of restoring tooth enamel is carried out using the device Air - FlowInside which are water-air channels and sodium bicarbonate, used as an abrasive agent. During the procedure, a stream of water, air and baking soda is applied to the surface of the tooth enamel under high pressure, which are mixed closer to the end of the device. The working part of the device is installed in a special connector, and water mixed with soda under high pressure is ejected, clearing the enamel surface from any, even the hardest, bloom in seconds.
Released jet easily penetrates the most inaccessible places. With its help you can clean the area above the gum and under various artificial structures, the gaps between the teeth. Literally in 30–40 minutes, the enamel will acquire its natural color.
Air - Flow technology has one big drawback - it does not clean tartar. In addition, prolonged exposure of the jet to one area may lead to increased sensitivity after the procedure.
Chemical bleaching
The procedure of restoring the whiteness of enamel using chemical means involves the use of special gels, which include highly concentrated hydrogen peroxide. Gels can be used alone or as an aid in photobleaching and laser cleansing.
Due to the high concentration of hydrogen peroxide dental chemical procedure has a good whitening effect. For one visit you can achieve a pronounced whiteness of tooth enamel. You can whiten it 5–7 tones at once.
The disadvantage of chemical clarification is enamel damage. It is restored by fluoridation and remineralization of the teeth.
The use of chemicals requires consultation with a dentist and preliminary preparation. It is not recommended to carry out the procedure in the presence of various artificial restorations.
Whitening
This method of bleaching involves the use of a special lamp, which serves as a catalyst, and gels with active substances. Under the influence of a lamp, oxygen is released from the gel, splitting pigments into enamel. As a result, the teeth are lightened.
Stages of the procedure:
-
Safety glasses are worn on the patient. In the oral cavity is installed gaborashirlitel. Due to such a plate to the mucous membranes provides full access. They are smeared with protective compounds and analgesics, protecting them from the negative effects of the gel and the lamp. For the cheeks fit cotton wool tampons. - A special whitening gel is applied. In some clinics, a special cap-shaped nozzle is put on the patient’s tongue. It protects the tongue from unpleasant sensations in the form of tingling.
- The procedure lasts about 15 minutes. During this time, the chemical components act on the enamel with a special lamp. The patient should sit almost motionless, since the lamp is in the mouth.
- The gel is washed off and applied auxiliary preparations. After that, in some cases two more sessions are held.
Tooth whitening is excellent with yellowing teeth, and gray bloom almost does not remove. In some cases, after the procedure, there is increased tooth sensitivity. In this case, the dentist prescribes the use of remineralizing pastes.
Home teeth whitening
At home, you can use both mechanical and chemical means of lightening tooth enamel.
To dental home whitening methods relate:
-
The use of various whitening toothpastes. It is necessary to use them with great care, as abrasive powders are part of the paste. They not only clean the coating, but also violate the structure of the enamel. - Teeth whitening with activated carbon. The drug has a double effect - as an abrasive, it removes plaque from enamel and neutralizes putrefactive bacteria and toxins. For bleaching used crushed coal tablets that are mixed with toothpaste or chewed in pure form.
- Use of hydrogen peroxide. Peroxide forms the basis of most dental whitening gels. At home, use a 10% solution. To remove yellow patches with peroxide, rub or rinse teeth. In the first case, the tooth enamel is wiped several times with a cotton swab moistened with a solution. To rinse 25 drops of 3% pharmacy peroxide diluted in a third glass of water. After each procedure, the mouth is rinsed with water.
- Whitening gel in kappa. The kit includes mouth guards, subdivided for the upper and lower teeth, and a special whitening gel. Before the procedure, mouth guards are filled with gel and glued to the teeth. The duration of the procedure may be different. Before use, you must read the instructions.
- Teeth whitening pencil. This is the easiest and most affordable dental method of lightening tooth enamel. The pencil contains a gel that contains carbamide peroxide. By the light of a special lamp, this tool emits free atomic oxygen, which penetrates deep into the enamel, removing pigmentation. With this procedure, you can lighten the enamel on 6-10 tones.
Contraindications for dental bleaching
No matter how desirable, but not everyone can whiten tooth enamel using dental procedures. Teeth whitening contraindicated in the following cases:
- tooth sensitivity;

Therefore, those who want to have white teeth should first weigh the pros and cons, and only then choose for themselves the best dental teeth whitening.
