Tooth whitening systems in dentistry

The main sign of a happy person is of course a happy smile. But there are times when people are just embarrassed to smile. This may be due to diseases of the tissues and elements of the oral cavity, unpleasant smell, missing teeth or yellowed tooth enamel. By the way, since dental clinics use a lot of popular and proven bleaching systems, the last situation can be coped with successfully. Further in the article we will tell you all about modern methods of teeth whitening in the clinic, and at home we will find out the opinion of dentists on the best method of whitening.

Classification of bleaching systems

All the available complexes for teeth whitening can be divided into two types - professional (performed only by a dentist) and for home use (performed outside the clinic). Below we will describe the classification of whitening methods in detail.

Important!Regardless of which method the patient has chosen for whitening, doctors recommend professionally cleaning the enamel 5-7 days before the procedure. This is necessary to qualitatively remove plaque and bacterial film. Otherwise, the clarification may not give the expected results.

Functions of professional systems

Whitening products and equipment used by dental hygienists are improving every year. The complexes made in the USA and Europe are mainly used - they have stood the test of time and give excellent results.

According to patient reviews, professional methods of teeth whitening in dentistry have a number of important advantages:

  • Speed ​​of performance: it only takes 1 visit before a smile shines,
  • Degree of clarification: The enamel becomes white by 8-12 tones,
  • makes the outer and inner color of the tooth enamel white,
  • The effect lasts 6 months to 3 years.

The shortcomings include the high cost, the pain associated with some methods, and the presence of contraindications.

Professional system technologies

In the dental clinic there are the following types of teeth whitening:

How is teeth whitening done in the clinic
  1. Chemical:A layer of gel containing hydrogen gel oxide is applied to the tooth enamel. After 15 minutes, it is washed off, the process is repeated up to 6 applications in one session. In addition to peroxide, fluorides and trace elements are added to such gels for remineralization. An important feature of this method is that the composition acts independently and without an external activator.
  2. Photo bleaching:The tooth enamel is also processed with a unique gel. Its components are activated by devices with bright aiming light (LED radiation or ultraviolet). Components, usually oxygen and hydrogen peroxide, lighten the tooth enamel and penetrate not only into the structure of the outer shell, but also into the dentin.
  3. -Laser:The activation of reagents takes place under the action of a laser. The bleach components penetrate the tooth enamel and facilitate pigmentation. An accurate and effective method that can sometimes even eliminate the effects of "tetracycline teeth". But it is also the most expensive.

Attention!Professional whitening is only carried out by a qualified specialist and only in a clinic. The dentist monitors the effects of medication and light equipment throughout the procedure. That is why such techniques are considered to be the gentlest and safest.

The above methods have worked remarkably well for darkening the outer tooth enamel. But what about patients who, after depulpation, got colored pigments into the inner tissue of the tooth? In this case, intra-canal whitening is used - the canal is cleaned, a temporary filling with sodium perborate is installed (it has an excellent whitening effect) and after 3-5 days the canal is closed with a permanent filling.

Home whitening systems

Everyone has bought a paste with a whitening effect at least once in their life - this is the most famous promotional product for lightening enamel. In recent years the shelves of shops and pharmacies have been replenished by other means. They are discussed below.

Types of home bleaches:

  • Complex for lightening 8-10 tones:contains a gel with an active ingredient and a universal silicone mouthguard, course duration 14 days,
  • Bleaching strips:You have a lightening agent on one edge that is securely attached to the teeth. The maximum whiteness is achieved by 10-14 methods (
  • ) found
  • Pencil gel:The fading of the tooth enamel by 2 tones is achieved by hydrogen peroxide. The composition is made with a special brush (
  • ) spreads
  • gloss gel:looks like a glossy enamel coating. Usually used in combination after applying a paste with abrasive particles.

Important to know!According to the reviews of patients who have experienced both professional and home bleaching, the latter method is significantly inferior to the former. The time to get the result is not 1-2 visits to the clinic, but 2-4 weeks. The effect is less than indicated in the ad - the actual lightening is a maximum of 2-3 tones.

Complex hygienic cleaning - alternative option

Whitening treatments can be harmful to some patient populations. In this case, the dentist will use safe professional hygiene practices. They are carried out in a clinic. Professional cleaning removes dark plaque and debris from tooth enamel and also brightens 1-2 tones. It can be used for carious lesions, gingivitis and periodontal disease during pregnancy and breastfeeding.

Hygienic cleaning methods:

  • Ultrasound: With the help of a scaler (ultrasound apparatus), plaque and plaques are carefully removed from the surface of the teeth.;
  • Air flow method:Enamel is cleaned with a suspension of water, air and the smallest abrasive particles. In addition to removing interdental deposits, the surface is gently polished. Recommended immediately after the ultrasound. A complex application leads to an excellent result in whitening tooth enamel.

The best teeth whitening system (according to experts)

According to dentists, the 4th generation zoom system is currently considered to be the best system for aesthetic whitening. The only difference to Zoom-3 is the activation lamp. In the new unit, you can change the strength of the ultraviolet and LED radiation directly during the procedure.

The bleaching gel contains 25% hydrogen peroxide, remineralizing ingredients and a light-sensitive activator. Under the influence of the lamp, the components of the gel begin to interact with the pigments in the tooth enamel and destroy them. At the same time, reducing substances get into the tissue.

Before the procedure, the patient is put on protective goggles and a retractor is attached to the oral cavity - so that the gel does not get onto the mucous membranes, the gums are lubricated with a "liquid rubber dam". The gel is applied to the front of the teeth, the zoom device is turned on. It is possible to run 3-4 applications in one session. After the procedure, the doctor will prescribe diet and hygiene promotion in order to achieve an excellent result.

“I doubted for a long time, but still decided to lighten the zoom. In about a week, she began preparing for the procedure - she underwent professional cleaning and restoration of tooth enamel. Before going to the clinic, I drank an anesthetic pill just in case. The procedure itself is completely painless. It took about an hour - there were 3 sets of 15 minutes. The doctor said that they have the latest equipment that allows you to choose the strength of the light radiation. In the evening my teeth ached a little, but in the morning I woke up like nothing had happened. 10 days later, my smile turned so white that I still can't get enough of it! I go and smile all the time. "

How to save the result for a long time

What not to do after teeth whitening

Bleaching is not enough for the effect of white teeth to last for a long time. After that, the dentist will prescribe a special diet and advise on new oral hygiene products.

In the first 10 to 14 days, the tooth enamel must not come into contact with dyes - food and cosmetics. For example, red juice, blueberries, beets, fresh carrots and herbs, coffee, wine, strong tea and ketchup are prohibited. Better to limit yourself to light foods. Smoking is also prohibited. Women should avoid using bright lipstick.

All patients are prescribed prophylactic whitening pastes and gels to fix rinses. However, the effect of the whitening wears off over time and the process must be repeated in about 1 to 3 years.
