Professional chemical whitening in dentistry

In order for the enamel surface to acquire a white color and not be damaged, it is better to contact a dental clinic. In this case, the procedure is performed professionally with a minimum likelihood of side effects.

There are the following types of chemical tooth whitening:

Photobleaching

The essence photobleaching consists in the fact that under the influence of ultraviolet radiation, a gel containing hydrogen peroxide is transformed into an active form of oxygen. Subsequently, it seeps through the enamel, penetrating to the dentin. In this case, the destruction of the pigmented areas occurs. To achieve a stable effect, the session is repeated after 10 days.

The procedure is divided into 3 stages:

1. Initially, the surface is cleaned from plaque and dental calculus.
2. Isolation of lips and cheeks is performed (using retractor), followed by the application of the gel to the dental units.
3. Irradiation with ultraviolet light is performed within 20 minutes.

Teeth cannot be processed more than 6 times in one visit. If the effect obtained is considered insufficient, then a second session is carried out in a week.

This type of whitening has worked well among people who abuse coffee, and smokers. Practitioners warn that in some cases, allergic reactions and irritation are possible. mucous membranes.

The price of photobleaching in dental clinics is from 4500 to 10000 rubles.

Laser

Method using laser allows you to whiten your teeth, even if they have a grayish tint. At the same time, in one visit to the dentist, the dentition can be lightened by 7 tones in half an hour.

To do this, use a special Smartbleach gel (based on hydrogen peroxide). Its activation occurs due to the action of a laser, which processes each dental crown for no more than 2 minutes.

The main advantage of this procedure is the preservation of the effect for 4 years. The main disadvantage is the high price. It is in the range of 25,000 rubles.

Zoom

Technology Zoom is a kind of photobleaching, but at the same time it is distinguished by high efficiency and long-term preservation of the whiteness of the dentition.

This method is performed in stages by analogy with photobleaching, with the difference that at the end of the procedure it is supposed to apply a special gel based on calcium phosphate. It restores the structural surface of the enamel, preventing it destruction, and thereby preventing the development of hypersensitivity.

The main advantage of this technique is the long-term preservation of the effect (from 3 to 5 years), provided that the patient adheres to medical recommendations. In addition, a snow-white smile is restored even with old plaque, and age spots are removed with fluorosis.

The approximate cost of one session is 8000 rubles.

Home techniques

If the front incisors are not damaged (there are no fillings and prosthetic crowns), then the procedure for chemical teeth whitening can be done at home. In this case, special kits are used, the use of which allows you to restore a snow-white smile, but no more than 4-5 tones. There are several home chemistry systems available, notably Opalescence and PearlSmile PearLight.

Opalescence

The set includes a special mouthguard, which is filled with a special gel before being placed on the upper and lower jaw. This eliminates the need for oxygen activation.

The positive effect of the Opalescence system will be observed if the following conditions of use are met:

1. It is necessary to wear a mouthguard per day for at least 30 minutes, and in advanced forms of darkening, the time is increased to 1 hour.
2. The treatment course should be performed continuously for 12 days.

Practicing dentists believe that this system cannot significantly whiten the tooth surface, and therefore recommend it as an additional procedure.

PearlSmile PearLight

In the complete set PearlSmile PearLight has a silicone tray, special gel and wipes, and an ultraviolet light emitting lamp.

The procedure is performed in the following sequence:

1. The required amount of gel is squeezed into the tray (one third of the package).
2. After attaching to an ultraviolet lamp, the mouthguard is placed in the oral cavity, after pretreating the teeth with napkins.
3. The ultraviolet source is turned on for 10 minutes with a 30 second break.

The manipulation is repeated for 30 minutes.

According to the manufacturers, three procedures will restore a snow-white smile in 9 tones, which makes this system popular among the population. In addition, many people like how much the procedure costs - around 2900 rubles.

The negative aspects of application include the inconvenience of placing the gel on the tray. If it is applied in an uneven layer, then the surface of the dentition will have pigmentation - the restored enamel will contrast with areas of unbleached teeth.
