Underbite – symptoms, treatment, causes

Underbite is one of the most common malocclusions, developing in children at an early age. The key causes of its development are abnormal bone development and unhealthy habits.

What is an underbite?

An overbite is the result of abnormal bone development and bad habits. It usually becomes visible when permanent teeth emerge, although primary teeth also contribute to its formation. It is most often diagnosed in children over 7 years of age. This defect is characterized by the incorrect position of the upper jaw, which is too protruding in front of the lower teeth.A common symptom of an overbite is a lack of contact between the upper and lower teeth.

Causes of underbite

An orthodontist can diagnose an underbite during a routine examination. It is good to undergo such examination because it is easy to miss the beginnings of this defect. The main causes that can lead to the development of an overbite in infants include:

  • vitamin D deficiency leading to weakening of bones during their growth,
  • inappropriate position while sleeping or feeding,
  • pathological cervical lordosis,
  • long-term use of a pacifier,
  • finger sucking
  • premature loss of primary lower incisors,
  • hereditary bone development disorders,
  • incorrect position of the tongue when the child’s mouth is constantly open.

The ideal time for an orthodontist to assess the position of dental arches is at the age of 7-8, when the process of replacing primary teeth with permanent ones takes place.
