Why do children’s teeth grow unevenly?

When children grow to a certain stage, they will start to change their teeth, and some children will have uneven teeth due to certain reasons. Many parents hope that their children can have straight teeth, so it is important to understand the causes of crooked teeth. There are two main reasons for uneven teeth. Let me introduce them to you one by one.

Congenital causes: The growth and development of teeth are affected by internal and external factors of the human body. When 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, this condition will be passed on to their children.

Acquired causes:

(1) Improper use of the pacifier. When feeding a child, if the bottle is positioned too far forward and upward or the baby lies flat on his back to feed, the lower jaw will be sucked forward, which will eventually cause the lower jaw and lower dental arch to move forward, compress the upper dental arch, and form an "overbite" deformity of the front teeth.

(2) Premature or late loss of deciduous teeth can cause uneven teeth growth. If the deciduous teeth are not treated in time, or they fall out due to trauma, the teeth on both sides will shift into the gap, making the gap smaller and causing the permanent teeth that erupt later to be uneven due to lack of space.

(3) When people have difficulty breathing through their nose due to enlarged tonsils or nasal diseases, they often switch to mouth breathing and sleep with their mouths open. As air flows through the mouth, the upper palate bulges upward, and the left and right sides of the upper dental arch become narrower. The front part of the upper dental arch protrudes forward, and the erupted front teeth are not only tilted forward, but also arranged in a disorderly manner, forming a face with open lips.

It is also important for children to develop good habits for their dental health as they grow up. Many children like to stick out their tongues or bite their fingers. In fact, this habit is very detrimental to the healthy growth of teeth. Biting your fingers will make your teeth

The upper and lower incisors protrude forward, causing microstomia. In addition, children need to maintain good oral hygiene.
