Are Genetics The Only Factor That Cause Crooked Teeth?

July 15, 2019

According to the American Association of Orthodontists, more than one-third American adults are not satisfied with their smiles. Smiles are the first thing people notice among social circles and gatherings.

We all want perfect teeth to be able to smile confidently. Sadly, this isn’t the case with everyone. Uneven or crooked teeth play a major role in hindering self-confidence as people are always apprehensive and reluctant to smile.

Many people believe that genetics play a huge role in the emergence of crooked teeth. Researchers have found a strong relation between our jaw structure and how it has developed over time through our genes. But this isn’t the only reason; we’ve listed the rest down for you.

They may seem like harmless habits, but with constant and slow pressure, can cause the teeth positions to change.

Are Genetics The Only Factor That Cause Crooked Teeth


Clenching or grinding of teeth leads to crooked teeth. Many people do this while sleeping and aren’t aware of it. Thumb sucking is very common among children and is carried till adulthood which causes the teeth to become misaligned.


An arched or a slouched position can lead to malocclusion which is when the upper and lower jaws aren’t aligned.

Slouching or resting your chin forward with your hand tends to cause pressure on the jaw. Bad posture surprisingly can lead to crooked teeth too. Slouching on a chair or computer leads to a crooked spine which will cause the lower jaw to protrude. Issues such as overbites and underbites are common which further aggravate the misalignment.


Scientists believe that due to the modern diet—where processed and soft food is consumed—chewing hard isn’t required. This has led to our jaws becoming smaller than the previous generations. As time has progressed, lesser chewing is required to extract nutrients from food. This had led to the shrinkage of the jaws which has contributed to crooked teeth.


Dentists have found that those who regularly sleep on their stomachs end up applying pressure to their teeth which can last the whole night.

This causes both the jaws and teeth to get misaligned due to the applied force. There is no certain age for it but can happen over time, regardless of the age.
