Crooked Teeth and Misalignment – Causes, Symptoms and Treatment


Many people suffer from crooked or misaligned teeth, which makes them reluctant to speak in public and causes them tend to hide their mouth. In orthodontics there are many options, even such where only the front teeth are fixed. There is always a treatment option that works best for you, so don’t give up and say “I can’t fix it anymore anyway”.

Causes of crooked and misaligned teeth

The causes of crooked and misaligned teeth can be broadly divided into the following three categories:

Inherited causes:
Heredity and malformation of the teeth during the fetal period can cause misaligned teeth.

Acquired causes:
Teeth can become misaligned due to finger sucking and tongue biting habits during infancy or diseases such as tooth decay and periodontal disease.

Malocclusion is a condition in which the teeth are not in their normal position or bite. There are several types of malocclusion, each with different causes and symptoms.


Symptoms of crooked and misaligned teeth

Symptoms of misaligned teeth may include:

  • Poor appearance of the teeth
  • Poorly aligned teeth
  • Susceptibility to cavities and gum disease
  • Poor pronunciation
  • Arthritis of the Temporomandibular Joint (TMJ)
  • Headaches and shoulder stiffness

Methods for Correcting Crooked and Misaligned Teeth

There are three main methods of orthodontic treatment for aligning teeth:

Wire orthodontics:
Wires or brackets are attached to the teeth in order to move them. This is the most common type of orthodontic treatment.

Mouthpiece orthodontics:
A mouthpiece is worn to move the teeth. It is less noticeable than braces and can be removed when you leave the house.

A clear mouthpiece is worn to move teeth. It is less noticeable and easier to remove than wire or mouthpiece braces.


Wire bracers





Cost of orthodontic treatment to straighten teeth

The cost of orthodontic treatment for straightening teeth depends on the orthodontic method and the length of treatment. For general wire braces, the cost ranges from several hundred thousand yen to several million yen. For mouthpiece braces and Invisalign, the cost tends to be higher than for wire braces.

Timing of Teeth Straightening

The earlier the teeth are straightened, the better. In general, it is good to start orthodontic treatment as soon as problems are detected, but no later than the age of 7. However, orthodontic treatment can also be done in adulthood.
