Wedge-shaped teeth defect

The most important enemy for teeth and the culprit of their destruction is caries. But there is another problem that has nothing to do with caries, called “wedge-shaped defect” (because of the corresponding shape of the enamel chips). A wedge-shaped defect is the destruction of the hard tissue of the tooth in the cervical region. Most often, enamel chips occur on the frontal teeth, that is, in the smile zone.

The problem has deep roots and requires an integrated approach to treatment. However, there are no unsolvable problems for modern dentistry. Read about why teeth are decaying and in what ways dentists solve this problem in the article.

Erasure of teeth and wedge-shaped defect: causes

For a long time, external factors were considered the cause of the wedge-shaped defect, namely, brushing teeth with abrasive pastes, chemical effects on enamel. The patient was recommended, first of all, to replace the hard brush with a soft one, to exclude from the diet foods containing acid dangerous for enamel (in particular, citrus fruits).

However, the real cause of tooth decay at the base, as well as tooth abrasion, is systematic mechanical stress. When chewing, the maximum stress falls on the root zone, and the enamel in this area just has the smallest thickness. First, microcracks on the enamel appear in this place, and then a wedge-shaped chip occurs.

Chewing stress is not the main cause of the wedge-shaped defect. For example, teeth wear out with age is observed in all people, and chips in the neck of the tooth are much less common. This indicates a fundamentally different mechanism for the development of pathology.

The root cause of the wedge-shaped defect is malocclusion. This is how it works:

  • 1
    The patient has a dental occlusion disorder and no orthodontic treatment has been performed.
  • 2
    With a defect in the bite, the load on the teeth during chewing is unevenly distributed.
  • 3
    Teeth, which have an increased load, are quickly erased, and the surface becomes flat at the place of erasure.
  • 4
    With flat, erased edges, the food is not cut by the incisors when biting off, but torn. This requires more effort and the teeth are stressed.
  • 5
    Due to the high load, the enamel is damaged at the base of the tooth, a wedge-shaped defect is formed.

According to statistics, the frequency of diagnostics of a wedge-shaped defect in patients increases with age.

Symptoms and stages of development of a wedge-shaped defect

The wedge-shaped defect develops in several stages:

  • 1
    At the initial stage, it is impossible to diagnose pathological changes visually without special optical equipment. Sensitive symptoms of the destructive process are also absent.
  • 2
    Superficial damage to the enamel. At this stage, signs of destruction become noticeable. On the enamel, cracks up to 0.2 mm deep and up to 3.5 mm wide are visible, there is a slight sensitivity of teeth with a defect.
  • 3
    Moderately pronounced defect. At this stage, the cracks acquire a wedge-shaped shape, are located at an angle of 45 °, increase in depth to 0.3 mm, and in width. There is a moderate reaction of the affected teeth to hot, cold, sweet, sour.
  • 4
    Stage of deep tissue damage. The defect is clearly visible. The destruction spreads in depth, increases in length up to 5 mm. The teeth become hypersensitive.

The wedge-shaped defect can extend to the deep tissues of the tooth and reach the nerve. In some cases, with deep tissue damage, the tooth crown is chipped. The problem usually affects several adjacent teeth.

Many dental diseases, pathologies in the initial stages proceed imperceptibly, and they can only be diagnosed with a professional examination using special tools and equipment. Therefore, Amel Dental specialists never tire of reminding patients of the need for regular preventive examinations in dentistry.

Treatment of a wedge-shaped tooth defect

The main principle of effective treatment of any disease is to fight not only the consequences, but also the causes. First of all, a patient with a wedge-shaped defect of teeth must undergo an examination by an orthodontist, who will diagnose and choose the optimal method of bite correction (aligners, installation of a bracket system).

Along with orthodontic treatment, according to indications, the patient can be prescribed the following treatment methods:

  • applications for the purpose of remineralization, strengthening of hard tissues of teeth;
  • desensitive toothpastes (with hypersensitivity);
  • filling using modern composite materials;
  • installation of veneers as part of the aesthetic restoration of worn out teeth, correction of minor occlusion defects;
  • installation of the crown.

Important! Orthopedic, therapeutic methods of treating a wedge-shaped defect by themselves (without orthodontic treatment) eliminate only the consequences, but do not solve the problem, since they do not eliminate the main cause of the defect – a violation of occlusion.

Prevention of a wedge-shaped defect: recommendations of Amel Dental specialists

Why wait for teeth to decay when it is possible to prevent wedge-shaped defects on the teeth? To do this, you just need to be more attentive to your health:

  • brush your teeth correctly;
  • do not often use whitening and other pastes that may contain components that are aggressive to enamel;
  • regularly visit the dental clinic – this will allow the doctor to identify a predisposition to tooth erasure and the appearance of a wedge-shaped defect and to eliminate the problem in a timely manner.

Some patients ignore the dentist’s recommendations for correcting minor malocclusion. In this case, the savings often lead to serious dental health problems, which are even more expensive and can cost a beautiful smile. Keeping your teeth healthy is much easier and cheaper than getting it back. Amel Dental specialists are ready to help you in solving any problems, but they urge you not to wait until the problem becomes global, but to treat your teeth on time.
