5 Habits that favor crooked teeth

5 Habits that favor crooked teeth

A survey by the American Association of Orthodontics (AAO) shows that 66% of the population has a problem of poor tooth positioning. However, archaeological studies indicate that our ancestors rarely had this problem.

Basically, orthodontics uses two forces to move teeth: pressure and traction. Anything that exerts one of these forces on the teeth is able to move it. Therefore, some habits can generate a wrong pressure on the teeth and jaw, and end up interfering in facial development.

Habits that favor crooked teeth

Common situations that generate pressure on the teeth are:

  • Sleeping In this position the face receives pressure. The pressure gets worse if you put an arm or something firmly under your head while sleeping on your stomach.
  • Support the face in the hands constantly for long periods: There is a pressure that can slowly push the teeth, resulting in crooked teeth side of the mouth, pain in the teeth and in the joint of the TMJ jaw.

In addition, some childhood habits when constant and for long periods can also cause problems:

  • Pacifier
  • Bottle
  • Toe suck or pencil

Factors that favor crooked teeth

Factors that may affect tooth development are:

  • Respiratory distress due to rhinitis
  • Tonsil and adenoid inflammation
  • Wrong projection of tongue when swallowing or speaking

But why is there such a significant increase in people with crooked teeth today?

In our body, any organ that is not exercised will not have development to its full potential. Even the organ that has reached its maximum development, if left to be used, will atrophy. Some theories have arisen trying to explain this increase in the index of bad positioning:

1. The jaws in modern man are underdeveloped, that is, smaller than the primitive peoples. This progressive reduction of the bones, not associated with the decrease of the size of the teeth, could lead to the bad alignment of the teeth, due to the lack of space for the same ones. The dietary habits of very soft diet, common nowadays, decrease the masticatory exercise and with that, it diminishes the stimulus for the development of the bones of the face. This conclusion was drawn from studies that noted a higher prevalence of malocclusion among urban populations compared to rural populations with more natural and harder eating habits.

3. The increase of cavities, due to a diet rich in sugar, leads to the loss of some teeth. Just one missing milk tooth before the exchange time, to unbalance the occlusion (tooth fitting) and to generate a derangement in the alignment of all other teeth.

Stem cells present in milk teeth contribute to health

Advances in stem cell research have led many people to search for stem cell collection and storage services contained in the milk tooth. "Today this is an investment for the future, since there are several therapies in the final stages of study, such as treatments for corneal degeneration, cleft lip and palate, and even heart attack," explains dentists Daniela Bueno, MD Genetics by the University of São Paulo and researcher in this area by the Sírio-Libanês Hospital.
