Bad Breath: Causes & Treatment

The problem of crooked teeth is observed in most people as they transition from adolescence to adulthood. Having crooked teeth not only affects your confidence but also makes you prone to various dental issues that can affect your oral hygiene. Among all the crooked teeth causes, genetics also play a role. Let’s take a look at this in detail.

Are Crooked Teeth Genetic?

Considering all the crooked teeth causes, genetics can significantly influence the development of crooked teeth in people. If your family members have previously developed crooked teeth throughout their life, then you can also be prone to the same issue. These issues can mainly occur in the form of underbites and overbites.

Other teeth misalignment issues developed in people due to genetics can include misalignment of the jaw, developing extra teeth, having larger teeth than usual, etc. If you are prone to crooked teeth issues due to genetic reasons, then you should take extra care to maintain your oral hygiene through good dental habits and routines. Apart from genetic influence, external factors are also responsible for crooked teeth in people.

External Causes for Crooked Teeth

Various external reasons can lead to crooked teeth. Being aware of these causes will help you to take better care of your teeth to avoid misalignment and the issues arising due to them.

Constant Wear and Tear

We regularly use our teeth for chewing, biting, and grinding food throughout our life. Our teeth experience stress and pressure throughout our life which leads to the gradual movement of teeth. With time, the health of our teeth also starts deteriorating leading to crooked teeth as we age.

Teeth Loss

We start losing our milk teeth in childhood which leaves room in our mouth at regular intervals. The remaining teeth start compensating for this space by moving into the space available which leads to crooked teeth. Pair this with improper eating habits and you are more prone to the occurrence of crooked teeth till you reach adulthood.

Tongue Posture

Believe it or not, your tongue posture plays a major role in having a good set of teeth that are straight and even throughout. Most people don’t know that your tongue should rest comfortably on the roof of your mouth. Improper tongue posture can leave insufficient space for your teeth, leading to crowding.

Evolution of Diet

It is believed that the evolution of diet in the last century played a significant role in modern-day dental problems. The industrial revolution pushed the consumption of processed food into an everyday diet that is soft and doesn’t require much chewing or grinding of food. This led to underdeveloped jaws and more dental problems such as a cavity, plaque, tooth decay, etc.

Before the industrial revolution, people used to savour a primitive and natural diet that exercised the jaw and teeth leading to healthy development. Our early ancestors had stronger jaws and better-aligned teeth without the invention of products that are required in the modern world to keep your teeth healthy.
