Má occlusionão dentária: what é, symptoms and treatment

Dental occlusion is the contact of the upper teeth with the lower teeth when closing the mouth. Under normal conditions, the upper teeth should slightly overlap the lower ones, that is, the upper dental arch should be slightly larger than the lower one.

Dental malocclusion is, then, any change in this mechanism, which can cause damage to teeth, gums, bones, muscles, ligaments and joints.

Although in most cases, malocclusion is very mild and does not require treatment, there are cases where it is quite severe, and it is recommended to consult a dentist to start treatment, which may include the use of appliances or surgery, for example.

Main symptoms

In addition to the aesthetic alteration, the symptoms of malocclusion can be very difficult to identify, as it is a problem that appears over time and, therefore, the person gets used to it, without realizing that their teeth are changed.

Still, some signs that may indicate that there is a dental malocclusion are:

  1. Teeth wear, causing teeth not to be smooth at the top;
  2. Difficulty with discomfort when biting or chewing;
  3. Frequent presence of caries;
  4. Loss of one or more teeth;
  5. Teeth with very exposed or sensitive parts, causing a lot of discomfort when eating cold or sweet foods;
  6. Frequent headaches, pain and ringing in the ears;
  7. Problems in the jaw joint.

In some cases dental malocclusion can also be responsible for causing bad posture and spinal deviations.

Which doctor to consult

Dental malocclusion is usually identified and treated by the dentist, who may order a dental X-ray to confirm the diagnosis, indicating the most appropriate treatment.

Types of dental occlusion

The main types of dental occlusion are:

  • Class 1: normal occlusion, in which the upper dental arch fits perfectly with the lower dental arch;
  • Class 2: the person appears to have no chin, as the upper dental arch is much larger than the lower arch.
  • Class 3: the chin looks very large as the upper dental arch is much smaller than the lower one.

How the treatment is done

Treatment for dental malocclusion is only necessary when the teeth are very deviated from their ideal position and usually starts with the use of orthodontic appliances to try to put the teeth back in the correct place. The use of this type of appliance can vary between 6 months and 2 years, depending on the degree of malocclusion.

During braces treatment, the dentist may still need to remove a tooth or place a denture, depending on the case, to allow the teeth to have the space or tension needed to return to their ideal place.

In the most serious cases, in which the alteration of the mouth is very accentuated, the appliance may not be able to place the teeth in the correct place and, therefore, the dentist may recommend having an orthognathic surgery to change the shape of the bones of the face.
