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.
- Teeth do not become crooked by chance and modern research reveals most orthodontic problems are the result of incorrect jaw development.
- Braces and extracting teeth in teenage years does not solve the underlying causes of crooked teeth and incorrect facial development.
- The most up-to-date evidence reveals hereditary factors or big teeth in small jaws are not responsible for crowded teeth or incorrect jaw development.
