Types of teeth whitening

To date, there are many dental practices, each of which differs in the following parameters:

• frequency and number of procedures;
• whitening speed;
• degree of patient involvement.

Modern preparations are offered for the procedures, manufacturers of which promise with their help safe and high quality whitening.Professional clarification is performed on modern equipment and is in high demand.

Methods of dental office whitening

With the professional cleaning of tooth enamel for the shortest possible time, can achieve excellent results of and long-lasting effects.At the same time during the procedures, there is a sparing effect of tooth enamel.

All dental office whitening products are divided into several methods:

• mechanical;
• chemical;
• laser;
• ultrasonic;
• photo bleaching.

Dentists primarily recommend mechanical cleaning.If this method does not give the expected result, then the patient is offered other types of procedures.

Mechanical whitening

The basis of dental mechanical cleaning is professional oral hygiene .With this procedure, you can get a very pronounced visual effect, although dentists do not consider it bleaching.

During the mechanical procedure, dental deposits are removed in the form of plaque and stones.As a result, the natural color of the tooth enamel is returned to the patient.And if he has a white enamel by nature, then a Hollywood smile is assured.

Many people who drink coffee, red wine, cola and smoke, as their natural enamel look, have forgotten for a long time.In these cases, resort to chemical preparations of , hydrogen peroxide, various pencils and strips is impractical.First of all, you need to hold oral hygiene in the dental office.

For mechanical cleaning, the effect occurs on deposits that are on the surface of the teeth.That's why this procedure is completely safe for the enamel.

But there are cases when, after dental removal of plaque and stones, the cervical area of ​​the teeth is open.As a result, teeth begin to react to hot and cold.Earlier, all these stimuli were saved by dental calculi.In this case, you need to contact a periodontist who will conduct the fluoridation of sensitive enamel and prescribe a treatment.

Among the most common mechanical methods of clarification, is the dental ultrasonic tooth cleaning .

Ultrasonic whitening procedure

Ultrasonic devices can easily remove both supragingival and subgingival stones.Ultrasound allows you to clean even the tooth enamel of a smoker, which can not cope with either professional brushes, or special toothpastes.

How does ultrasound work?

At the end of the special tip, due to ultrasonic vibrations, plaque and stones are destroyed.Separating from the enamel, the fabric they do not hurt.At the same time, water enters the teeth through the nozzle, which is necessary for the effectiveness and safety of the procedure.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.

Technology Air-Flow

The procedure for the restoration of tooth enamel is carried out by using the Air-Flow apparatus, inside of which there are water-air channels and sodium bicarbonate, used as an abrasive.During the procedure, a jet of water, air and baking soda acts on the surface of the enamel under high pressure, which are mixed closer to the end of the apparatus.The working part of the device is installed in a special socket, and water mixed with soda under high pressure is thrown out, for seconds cleansing the surface of the enamel from any, even the hardest plaque.

The released jet easily penetrates into the most inaccessible places.With its help you can clean the area above the gum and under various artificial designs, the spaces between the teeth.Literally in 30-40 minutes the enamel will acquire its natural natural color.

Air-Flow technology has one big drawback - tooth stones it does not clean .In addition, prolonged exposure of the jet to one area can lead to increased sensitivity after the procedure.

Chemical whitening

The procedure for restoring whiteness of enamel by 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 cleaning.

Due to the high concentration of hydrogen peroxide, the dental chemical procedure has a good whitening effect.In one visit, you can achieve a pronounced whiteness of tooth enamel.It can be bleached directly for 5-7 tones .

The disadvantage of chemical clarification is the damage caused by the enamel.It is restored by fluoridation and remineralization of teeth.

The use of chemicals requires the advice of a dentist and a preliminary training.It is not recommended to perform the procedure in the presence of various artificial restorations.

Photobleaching

This method of bleaching involves the use of a special lamp that serves as a catalyst, and gels with active substances.Under the influence of a lamp, oxygen is released from the gel, splitting pigments into the enamel.As a result, the teeth become light.

Stages of the procedure:

1. The patient is wearing safety glasses.In the oral cavity, a gavage extender is installed.Due to such a plate, full access is provided to the mucous membranes.They are lubricated with protective compounds and analgesics, protecting them from the negative effects of the gel and the lamp.Touches of cotton wool are put on their cheeks.
2. A special whitening gel is applied.In some clinics, the patient's tongue is worn with a special cap in the form of a cap.It protects the tongue from unpleasant sensations in the form of tingling.
3. 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, as the lamp is in the mouth.
4. The gel is washed off and auxiliary preparations are applied.After this, in some cases, two more sessions are held.

With yellowness teeth, photobleaching cope perfectly, and gray plaque almost does not remove .In some cases, after the procedure, there is an increased sensitivity of the teeth.In this case, the dentist appoints the use of remineralizing pastes.

Home teeth whitening

At home, you can use both mechanical and chemical means of clarifying tooth enamel.

To dental home whitening methods are:

1. Application of various whitening toothpastes.Use them with caution, because the composition of pastes include abrasive powders.They not only clean the plaque, but also disrupt the structure of the enamel.
2. Teeth whitening with activated charcoal.The drug has a double effect - as an abrasive it cleans the enamel from the coating and detoxifies putrefactive bacteria and toxins.For bleaching, rastolchennye carbon tablets are used, which are mixed with toothpaste or chewed in a pure form.
3. Use of hydrogen peroxide.Peroxide is the basis of most dental whitening gels.At home, a 10% solution is used.To remove the yellow coating with peroxide, rub or rinse the teeth.In the first case, the tooth enamel is wiped several times with a cotton swab dipped in the solution.For rinsing 25 drops, 3% of pharmacy peroxide is diluted in a third of a glass of water.After each procedure, the mouth is rinsed with water.
4. Whitening gel in kappa.The set includes kappas, divided for upper and lower teeth, and a special gel for bleaching.Before the procedure, the mouthguards fill with gel and stick to the teeth.The duration of the procedure can be different.Before use, you should read the instructions.
5. Pencil for teeth whitening.This is the simplest and most accessible dental way of brightening tooth enamel.The pencil contains a gel, which contains carbamide peroxide.In the light of a special lamp, this means emits free atomic oxygen, which penetrates deep into the enamel, removing pigmentation.With this procedure, you can lighten the enamel by 6-10 tones.
