What to do if the lower jaw protrudes more than the upper jaw

We often see people whose lower jaw protrudes more than the upper jaw. Such people have a longer lower jaw and a shorter upper jaw, so the lower teeth are in front of the upper teeth. This phenomenon is what we often call overbite. There are many reasons for this phenomenon.

The most important factor is genetic factors. Generally speaking, when a child has this phenomenon, the child's parents may also have this phenomenon. Let us take a closer look at the situation where the lower jaw protrudes more than the upper jaw.

Overbite, medically known as crossbite and popularly known as "underbite", is a common dental malocclusion. For children with overbite, there are three opportunities for treatment:

The first stage: the occlusion period of deciduous teeth. The best age for treatment at this stage is about four years old. At this time, the child's permanent teeth have not yet erupted and the roots of the deciduous teeth have not been absorbed. Treatment can be carried out by wearing removable appliances in the mouth. The course of treatment is about six months. Early treatment at this stage is of great benefit to the normal growth and development of the child's maxillofacial area.

The second stage: the occlusion period. After the child's four upper and four lower front teeth are replaced, he or she can continue with orthodontic treatment when he or she is about eight or nine years old. Depending on the severity of the child's deformity, removable or fixed appliances can be used from mild to severe, or even extraoral plastic surgery can be used to correct the teeth. If the treatment is timely, it will be very helpful for improving the child's facial shape and growth and development.

The third stage: permanent tooth occlusion period. Children's deciduous teeth are replaced around the age of twelve, when they are at the peak of their growth and development. At this time, children who still have overbite can continue to receive correctional treatment. Since the growth of the child's mandible and height are basically synchronized, it is still necessary to observe until the child's peak growth and development period is over after overbite correction is completed. It should be noted that orthodontic treatment should be performed in large hospitals and by doctors with extensive experience.

You can check your individual situation to see if there is any crossbite, and then get corrective treatment based on your individual situation.
