Why Do Teeth Grow Crooked?

Misaligned TeethNot everyone has a set of great-looking teeth, and the condition can affect not only your smile but also your confidence and health. Some people deal with the stress, discomfort and anxiety of having a set of less than perfect pearly whites – for instance, when one has crooked teeth. Numerous problems can arise from having crooked teeth; among these, gum disease, tooth wear and tear, tooth injuries and difficulties in chewing,

Dental practitioners consider crooked teeth a major dental issue with various effects on oral health. Misaligned teeth can also have a negative impact on mental health, as well; due to the potentially confidence-damaging situations which may arise as a result of the problem.

What are some of the causes of this condition, also known as malocclusion, exactly?

Societal ‘Advancements’

Malocclusion has long been a dental problem. Experts in the past tried to deduce what causes this phenomenon, and they came up with controversial conclusions. Back in the 1940s, it was thought that racial inbreeding was the cause, although authorities in the field have since proven this wrong.

Other, more logical reasons included the drastic change in human diet. A study published in the Proceedings of the National Academy of Sciences notes how, 10,000 years ago, humans shifted from being hunter-gatherers to farmers. Upon examination of ancient hunter-gatherer and farmer skulls, the researchers noticed that the latter had shorter, wider jaws. The former had narrow, jutting jaws. Short jaws evolved as a way of adapting to the consumption of softer foods (i.e. crops instead of freshly killed meat). A short jaw also means that there’s less space for teeth to grow. This results to teeth crowding.

An Ugly Inheritance

Babies inherit a lot from their parents. Just like they may inherit hair colour, nose shape, eye colour, and everything else, they can also inherit their parents’ dental structure. This goes to show that crooked teeth may very well be genetic, though not in an entirely ‘conventional’ way.

Studies show that shorter, smaller jaws provide less space for teeth to grow in. In babies, the situation can go like this: the little one inherits the father’s large teeth and the mother’s smaller jaw. Thus, there’s not enough space for those sizeable teeth to fit, as they grow. As soon as teething kicks in, each tooth ‘fights’ for position in the jaw, leading to unsightly crowding.

Taking note of these reasons can be helpful if you’re seeking treatment soon. It’s fortunate that practices such as Jiva Dental offer Invisalign, a great treatment option for crooked teeth. Given the right circumstances, the treatment can provide visible results within just several months. Look into Invasalign, as a viable solution for crooked teeth.
