Researchers distinguish

two groups of causes

, due to which the teeth may not look perfectly white: internal and external staining.

Internal staining is associated with the characteristics of the body. Here are its main reasons:

  • heredity - then your teeth by nature will be slightly yellower than those of the same age;
  • age - over time, the enamel wears out and yellow dentin begins to shine through it;
  • high level fluorine content - fluorine strengthens the teeth, but at the same time it can give them a yellowish tint;
  • taking antibiotics and changing the color of fillings .

External staining is associated with environmental factors: from smoking to food and drinks that contain a lot of coloring substances (pigments ) In this situation, the teeth turn yellow due to the composition of the food.

For example, if a person drinks a lot of tea, coffee or cola , the colored substances from these products settle on tooth enamel, and the teeth turn yellow.

In some people, the enamel is yellowish due to the pigment that is part of it. There is no need for whitening, this is a purely aesthetic procedure.

As a rule, teeth whitening does not harm. Moreover, in home remedies with high concentrations of hydrogen peroxide, the destruction of the yellow pigment occurs at a lower 87H, that is, in an acidic environment.

As a result, minerals (calcium and fluoride ions) are “drawn out” from enamel - teeth are demineralized. Because of this, teeth can become more sensitive.

The same thing happens with enamel every day when we eat carbohydrate-rich foods. It is not worth using “acidic” whitening products for the same reason that you do not need to eat too much sweet : this can cause tooth decay .

But if you properly prepare for whitening, that is, remineralize the teeth before and after whitening, there will be no harm and tooth sensitivity will not increase.

You can whiten your teeth in several ways. If we are talking about whitening (and not about

professional hygiene

of the oral cavity or about Airflow - this is brushing your teeth with air flow, which sometimes erroneously called bleaching), then this procedure is always done chemically.

Here are the two most popular types of chemical bleaching :

  1. Simple chemical , or "office", - whitening without activation by light, mainly with hydrogen peroxide. Since peroxide bleaching creates an acidic environment that “pulls” mineral substances from enamel, this method is considered aggressive.

  2. Chemical with light activation - with this type of whitening, the solution applied to the teeth is illuminated by a lamp, thereby activating. This method does not damage the enamel and therefore is considered sparing. In the latest generations of such systems (for example, Zoom 4), the concentration of the bleaching agent is lower than in "office" bleaching, and 160H is neutral.

Strips, gels, and other devices that can be purchased at the store or on the Internet have a very low concentration of bleaching agent. The effect, most likely, will not be.

Sometimes in advertising you can see laser or ultrasonic whitening. But it is rather marketing. These methods are ineffective.

In the whitening strips there is a very low concentration of the active substance, and you need to apply them on the teeth daily. As a result, teeth lose much more minerals than in the dentist’s office, and their whitening effect is weak.

There is another problem. Since buyers use the strips at their own risk, without consulting dentists, there is a risk of overdoing it. This can lead to excessive tooth sensitivity, gum irritation, enamel demineralization.

This is a fairly effective way of whitening: gel for mouthguards are produced by professional manufacturers, such as O192alescense or Zoom.

Mouthguards are made according to individual casts.

At home you will need to fill the mouthguard with a special gel and put it on. Depending on the composition of the solution, the system will have to be worn from several minutes to several hours a day. At the same time, the funds are used less concentrated than those used by the dentist, so you have to use the mouthguard for a long time - up to two weeks.

There are two types of whitening pastes.

Abrasive pastes remove the yellow pigment from the enamel, almost like sandpaper. The abuse of such pastes threatens with increased tooth sensitivity. In addition, abrasive pastes return only a natural color, the reaction of chemical clarification does not occur.

Enzyme pastes cleave plaque without damaging the enamel. They also only restore the teeth to their natural color without brightening them.

Pasta with soda remove only traces of tea and coffee. Such pastes are not able to cope with natural yellowness.

Hydrogen peroxide from a pharmacy cannot whiten teeth, because there is too low concentration of active substance for this. The benefits of pharmaceutical peroxide are about the same as those of apple cider vinegar, activated carbon, kaolin clay, coconut oil and fruit peel. If these tools really worked, no one would have whitened their teeth at the dentist.

Zoom 4. With this technique, a special gel is applied to the surface of the teeth, which is activated by the light of an ultraviolet lamp. The ultraviolet light is cold, so it does not heat the gel and the surface of the teeth, so the procedure is painless. And since the 258H gel is close to comfortable for the teeth, enamel does not demineralize during bleaching. The effect of the procedure is excellent: the teeth become whiter by several tones.

The Zoom 4 * method can only be used in a dental clinic, because before bleaching it is necessary to carry out professional cleaning of the oral cavity and remineralization of the teeth. This will help strengthen the enamel and avoid excessive sensitivity. Whitening is done in one visit and takes 45-60 minutes .
