Malocclusion Symptoms & Causes

In-Depth

What causes malocclusion?

There is no one single cause of malocclusion. Many different factors are involved, including genetic factors and/or environmental factors.

  • Children who suck their thumbs or fingers beyond the age of 5 have an increased chance of developing malocclusion.
  • Children with a very small space between their baby teeth are at risk for having problems with malocclusion when their permanent teeth appear, because the permanent teeth are larger and require more space.
