What is the cause of baby teeth overbite?

There are many common dental problems. When solving dental problems, you should choose simple methods so as not to damage the teeth. Many people choose methods randomly when solving dental problems, which is of no help to the teeth and will induce dental diseases. So what is the matter with baby teeth being overbite? The following is a detailed introduction to this type of problem so that parents can have some understanding.

What is the cause of baby teeth overbite?

There are many factors that lead to overbite, such as genetic factors and the influence of some systemic diseases. Here I would like to draw the attention of parents that some factors caused by bad habits are still related to you. For example: During the breastfeeding period, if the baby is held in the supine position to be fed with a bottle, the lower jaw needs to push forward to suck hard, which can cause "overbite".

For example, if you don't pay attention to your child's bad habits of biting the upper layer, which causes the lower jaw to protrude, it will gradually lead to reversed front teeth and protrusion of the lower jaw. Some children suffer from chronic inflammation and hypertrophy of the tonsils in their mouths, which makes breathing difficult and causes the mandible to protrude forward to increase space for breathing, which eventually causes mandibular protrusion.

During the child's tooth replacement period, if the deciduous front teeth are retained, it means that they should fall out and give way to their successor permanent teeth, but they still remain in place. This causes the position of the subsequent permanent teeth to erupt abnormally. If the maxillary deciduous central incisor is retained, the maxillary permanent incisor will erupt on its palatal side (i.e. behind it). When retained deciduous teeth fall out, the maxillary incisors are easily wrapped up in the oral cavity by the mandibular front teeth when the upper and lower jaws bite, resulting in the lifting of individual teeth. Therefore, parents can still play a very important role in preventing the occurrence of overbite.

How to prevent and treat "underbite"?

First of all, during the infant and toddler period, parents should pay attention to the correct breastfeeding posture, always pay attention to changes in the child's oral teeth, and promptly discover and correct bad habits such as biting the upper lip and sticking out the tongue. At the same time, actively prevent the occurrence of caries. If a child has mandibular protrusion or severe underbite, he or she needs to go to the hospital to see a doctor as soon as possible. The best time for correction is between 3 and 5 years old. Because there is a great possibility of changing tooth position and moving the mandible during the deciduous teeth period, many simple removable appliances have good therapeutic effects, and functional appliances can also produce good results. The course of treatment is generally 3 to 5 months.

If crossbite occurs when permanent teeth erupt, early orthodontic treatment should be performed to prevent it from affecting the child's appearance in the future. Otherwise, as age increases and bone development is completed, treatment becomes more difficult. It should be noted that although crossbite has been corrected, it may still recur before growth and development are completed. Patients who have undergone correction still need regular checkups to observe the development of the jaw and teeth to prevent recurrence of crossbite.

After understanding what is causing the overbite on baby teeth, when improving this problem, you need to follow the doctor's advice. Moreover, after the overbite on baby teeth appears, it needs timely treatment. Otherwise, if it becomes serious, it will also affect the growth of baby teeth, making future treatment more responsible.
