What is the cause of the child's crooked teeth?

Many children have crooked teeth. Parents are worried about their children's future image. So when many children have crooked teeth, many parents want to know more about it. What is the cause of crooked teeth? In order to help you solve this problem as soon as possible, please read the introduction below. I hope it will be helpful to your child.

There are many reasons for uneven teeth, but the main reasons are congenital and acquired, and the acquired reasons are more important. Congenital causes: The growth and development of teeth are affected by internal and external factors of the human body. If the fetus is stimulated in the mother's body, or the mother is ill or malnourished during pregnancy, it will affect the normal development of the fetus's teeth and jaws, causing the teeth to be misaligned after they erupt. If parents have crooked teeth, it will be passed on to their children. Acquired causes include the following:

1. The method of using the pacifier is incorrect. When feeding your baby, if the bottle is positioned too far forward and upward, or if the baby lies on his back for a long time to feed, the lower jaw will suck forward, and over time the lower jaw and lower dental arch will move forward, the upper dental arch will be compressed, and the front teeth will form an "overbite" deformity.

2. Premature loss or retention of deciduous teeth can cause uneven teeth growth. If caries in deciduous teeth are not treated in time, or if they fall out due to trauma, gaps will appear. At this time, the permanent teeth have not yet erupted, and the teeth on both sides will shift into the gap, making the gap smaller. As a result, the permanent teeth that erupt later will not have enough space and will be crooked and move in and out.

3. Enlarged tonsils or nasal disease make it difficult to breathe through the nose, causing you to breathe through your mouth and sleep with your mouth open. As air flows through the oral cavity, the upper palate is subjected to upward pressure and cannot develop downward normally, causing the upper palate to bulge upward. The left and right sides of the upper dental arch also become narrower, and the front part of the upper dental arch protrudes forward. The erupted front teeth are not only tilted forward, but are often arranged in disorder, forming a facial shape with open lips and exposed teeth.

4. The impact of bad habits on teeth is as follows:

1. Sticking out or biting the tongue: When the front teeth are about to erupt, there will be mild discomfort or itching on the gums. Some children like to stick out their tongues, lick their gums or bite their tongues. Over time, the habit of sticking out or biting the tongue is formed, which causes the erupting teeth to be blocked by the tongue, and the upper and lower incisors cannot contact each other, resulting in a deformed incisor opening.

2. Licking teeth with the tongue: During the loosening period of deciduous teeth, some children like to lick them with the tip of their tongue. After forming a habit, they lick the newly erupted permanent teeth. The licked teeth are pushed outwards, and over time, the crowns of the teeth tilt forward and open in a fan shape. The upper and lower lips are not easy to close, resulting in an "open lips and exposed teeth" deformity.

3. Biting fingers or pencils: Some children like to bite their fingers, or put pencils between the upper and lower teeth. As a result, the upper incisors protrude forward, the lower incisors move backward, the teeth become shorter, the upper and lower teeth cannot touch each other, and the teeth are crowded and uneven, which manifests as a small mouth deformity. Educate the baby not to lick the teeth with the tongue when they are growing, and then wear corrective braces.

What's the matter with children's crooked teeth? This article gives a detailed introduction, so many parents can have a specific understanding of the above content and understand why their children's teeth are crooked. Then carry out targeted and effective correction. I believe that after a period of correction, their children's teeth can be straightened as soon as possible.
