wedge-shaped defects - non-carious tooth pathology of nature, in which the formation of V-like defect in the enamel of the tooth in the cervical area.Wedge-shaped defects that tend to occur in the canine and premolar (small molars).If abnormality is observed on one tooth, almost one hundred percent probability after a while it will be possible to detect and to neighboring teeth.

Signs and step wedge defect

accepted to distinguish four stages of a wedge-shaped teeth damage:

first stage - initial.The wedge-shaped defect at this stage it is difficult to notice, he weakly manifested visually and does not manifest symptomatically.

second stage - surface.Deepening the tooth neck reaches about 0.1 mm.

At its third stage - the average, wedge-shaped defects increases in size and deeper into the tooth enamel by 0.2-0.3 mm.

fourth stage wedge defect - deep.The depth of the

wedge reaches half a centimeter, he "gets" to the dentin and pulp chamber.

In its first stage, the disease does not bring discomfort in most cases people do not even notice it.Often, and in a second step the wedge-shaped teeth defect does not manifest itself symptomatically.His only sign - unaesthetic appearance of the tooth.But over time, the defect deepens (third and fourth stage), the person begins to disturb the high sensitivity of the teeth.They begin to respond to short-term, but the piercing pain to hot, cold, sweet, sour, and mechanical stimuli.

not need to wait for the onset of symptoms, should proceed to the treatment of a wedge-shaped defect immediately after its detection.

causes of pathology

To date there is no consensus among dentists about the causes of the wedge-shaped teeth defect.Most of them are inclined to believe that the destruction of the tooth provoke a liquid and / or gaseous food (fruit, sparkling water), as well as systematic mechanical tooth damage (for example, a hard bristle toothbrush).Assumptions Some dentists refute their other colleagues, who believe that the cause of the wedge-shaped defect should be sought in the internal processes and diseases of the human body, such as a problem with the thyroid.Until the end it is not known whether these factors cause a wedge-shaped defect, but the reason for its development, they certainly are.

In addition, the emergence of this disease can be triggered by improper bite (occlusion).Improper occlusion leads to uneven distribution of the load on the teeth.Thus, enamel permitting a greater load, and cracking usually occurs in this part of the tooth root.

All versions of the causes of the disease have the right to life.Therefore, the correct choice of methods of treatment of a wedge-shaped defect, it is necessary to consider each case individually incidence of this pathology.

Treatment wedge defect

Dentistry wedge defect occurs in two ways:

1. Eliminating disease symptoms

2. The immediate elimination of the defect

To get rid of the symptoms, ie the elimination of hypersensitivity of the teeth, on thetheir defective area is applied paints, ointments, mineral-rich solutions.This method facilitates the condition of the person, as good takes sensitivity, but we must understand that it has no effect on the defect itself.

function desensitization also perform qualitative desensetivnye toothpastes.

The most common method of treating a wedge-shaped defect of tooth - filling.Through sealing the tooth becomes nice and smooth, no sign of the former defect is not observed, the pain disappears.But the fragility of fillings spoil the overall positive picture of the method.Seals often drop out (in full or in part) or delaminate from the tooth, leading to a resumption of the wedge-shaped defects and dental caries lesions.

second method, used in the treatment of wedge-shaped teeth defects, - installation of porcelain veneers.Veneers - ceramic tiles is the front and the chewing surface of the tooth.In contrast to the filling, vinirovanie in many cases eliminating the very cause of the defects.The disadvantage of the method is that the structure, usually fragile and often can not withstand the load on the tooth.

At the fourth stage of the disease the use of any other method of treatment other than the installation of crowns - is useless.It is important to set the crowns.Their improper installation leads to the destruction not only of defective teeth, but also the adjacent teeth.

If the cause of the defect in a wedge-shaped teeth malocclusion, before starting treatment should be correct bite.The process of correcting occlusion in a long time, but the results are almost always excellent.


prevention of wedge-shaped teeth defect must include the following actions:

1. Proper tooth brushing technique.It is important to remember that the horizontal movement of the toothbrush are not allowed.Movements should be vertical.

2. Using the calcined and fluorinated toothpastes.

3. To prevent the attenuation of the enamel, it is important to time to treat oral diseases (gingivitis, periodontitis and other).

4. Conducting remineralizing dental care, ie saturation of the tooth enamel so necessary to her fluoride and calcium.

5. Early treatment of thyroid diseases.

6. Elimination of malocclusion.
