What is the cause of crooked teeth? Why is the tooth crooked?

Crooked teeth and their lack of coordination is a very common problem among different people. This problem can be seen in both children and adults. Teeth that don’t match perfectly and proportionally, or more simply, are uneven, will reduce the attractiveness of your teeth.

If you are not satisfied with the appearance of your teeth and therefore the appearance of your smile, or if the crookedness of your teeth causes health or speech problems, you can straighten them and have an impressive and beautiful smile. In this article, you will learn more about the main causes of crooked and uneven teeth, as well as how to correct the position of the teeth in order to straighten the teeth.

What factors cause crooked teeth?

Both baby teeth and permanent teeth can become crooked over time. In children, due to lack of space or small upper and lower jaws, there is not enough space for teeth to grow. Therefore, teeth come out of unusual paths and continue to grow in an inappropriate way.

Having some inappropriate habits such as finger sucking or objects and toys in childhood can cause crooked milk teeth in children. Heredity and genetics may also play a role in crooked teeth.

Having crooked milk teeth does not mean that your child will have crooked permanent teeth. However, if there is not enough space for the teeth to grow, you should wait for your child’s permanent teeth to fall out.

Other things that can affect crooked or uneven teeth include:

Jaw size

The modern diet and the soft, processed foods that many people consume require less chewing than the foods our early ancestors ate. This change has caused the size of the human jaw to change over time, and in general, people today have smaller jaws. Scientists believe that our short and evolved jaw may be responsible for the crowding, misalignment and crookedness of our teeth.

Poor performance habits

Functional habits are repetitive behaviors that affect the muscles or functions of the mouth or face. Some of these habits are:

  • thumb sucking
  • Excessive use of pacifiers or bottles
  • Tongue contact with teeth
  • mouth breathing


Malocclusion refers to the misalignment of the teeth and their lack of coordination in the upper and lower jaws. When the natural alignment of the teeth and jaws is disturbed, it is said that a person has malocclusion.

The most common types of malocclusion include overbite and underbite. If you have an overbite, the front teeth in your upper jaw protrude a relatively large distance from the front teeth in your lower jaw. And if you have an underbite, this will be the other way around and your lower jaw teeth will be in front of your upper jaw.

Genetics and heredity

If one or both of your parents have crooked and crowded teeth, chances are you will also suffer from this problem. If you inherit crooked teeth, you may even have more problems with crooked teeth than your parents.

Poor dental care

When you visit a dentist regularly, all possible problems with your teeth will be diagnosed as soon as possible. And their treatment will also be easily solved at the very beginning of their appearance. But if you don’t pay attention to your oral and dental hygiene and don’t go to the dentist, you should see many dental problems in the future.

Poor nutrition

Poor nutrition, especially in children, can lead to tooth decay and poor growth. All these problems can lead to crooked teeth of your children.

Facial injury

A blow to the face or mouth can dislodge the teeth and cause one or more teeth to be knocked out.

Problems and complications caused by crooked teeth

In some cases, crooked teeth can affect your quality of life. For example, misaligned and misaligned teeth may affect your ability to chew and cause pain in your mouth every time you eat.

In addition, some people may be embarrassed to open their mouth or smile due to the ugly or irregular shape of their teeth. Other problems that can be caused by crooked teeth include:

  • Periodontal disease: When the teeth are uneven, it is difficult to clean between them. This condition can lead to tooth decay and gum disease. If left untreated, gingivitis can lead to periodontitis. Periodontitis is a serious infection that can cause damage to bones and teeth.
  • Difficulty chewing food: Crooked teeth can also interfere with the process of chewing food, which may cause problems with digestion.
  • Excessive wear: Crooked teeth can also cause teeth to wear together. Sometimes you may bite your tongue, lips or lips.
  • Speech problems: If your teeth are in the wrong position, they can cause you problems in the way you say and pronounce some words and letters.
  • Decreased self-confidence: Dissatisfaction with the appearance of your face can lead to a feeling of lack of self-confidence in you and, as a result, your social isolation.
