Are crooked teeth hereditary?

Modern research reveals the real causes

What Causes Crooked Teeth?

Majority of children now have crooked teeth, which is evident from five years of age and is often attributed to hereditary factors. However, rather than blame genetics for crooked teeth and poor jaw development, modern research has produced evidence that points to other causes.

Mouth breathing, tongue thrusting, reverse swallowing and thumb sucking (known as incorrect myofunctional habits) are the real causes.

Allergies, asthma and an open mouth posture also contribute to incorrect jaw development. Growing up, most of us have had one or more of these myofunctional problems, which may have been the cause of incorrect dental and facial development.
