Many factors are involved in the development of these problems. We generally classify them into two categories:
A)Hereditary factors: when a child has inherited the specific dysfunction from their ancestors (e.g. a case of prognathism found in one of the parents or grandparents) B) Environmental factors: while the genetic information is correct, certain factors alter its correct expression, causing it to deviate from the norm:
Loss of space due to premature extraction of a baby tooth.
