Why Do Some People Have Crooked Teeth?

May 16th, 2018

While a small percentage of people are lucky enough to have straight teeth, most must seek an orthodontist San Tan Valley AZ company to get a perfect smile. Why does this disparity exist? Even two people within the same family can have very different orthodontic issues and require varying levels of care. The answer to this is genetics.

Evolution
It is commonly thought that humans have reached the pinnacle of their evolution, but the reality is the process has not quite finished. Going back in time to Homo habilis, Australopithecus and Homo erectus, who were ancient ancestors of current humans, there is a clear trend of the mouth and jaw reducing in size. Today, human jaws are the smallest they have ever been. Teeth have not caught up to this yet, which is why many people have to wear braces. A typical adult jawline cannot support a set of 32 teeth. This is why the majority of people have their wisdom teeth pulled and why the other teeth come in crooked, requiring orthodontic treatment. It is not fair, but genetics are the reason some people get lucky with their teeth and others need a little help.

Habits
While genetics play a strong role, bad habits can also lead to crooked teeth. For example, thumb sucking is common in babies and toddlers, but if it goes on for too long, it can cause the front teeth to change angles, leading to an open bite. Another problem is tongue thrusting or throwing the tongue forward against the teeth when swallowing. These small habits may seem harmless, but they can change the way teeth come in and may result in a condition called malocclusion, which is a bad bite.

Solutions
Those who need orthodontic care have more choices than in previous years. While most go the old-fashioned route with metal braces, there is also the option of a modern solution like Invisalign. The process of straightening teeth can be complex, which is why finding a good orthodontist is very important.

Crooked teeth are often caused by genetics, but that does not mean a person has to live with the condition. Orthodontic care can make all the difference.
