In the mixed deciduous period, dentine reverse jaw and functional reverse jaw should be corrected as soon as possible. The orthodontic treatment can be considered at the age of three or four. When the child is 3 to 4 years old, as long as he can cooperate with doctors who will take an impression in his mouth, the treatment can begin. Generally, a relatively good treatment effect can be achieved in a short time. If you wait until the child is 6 to 7 years old before starting treatment, the treatment effect will be impacted because the child enters the dental transitional period.
The orthodontists used to tell us that it's best not to wait until all deciduous teeth are replaced before starting the orthodontic treatment, because it usually takes eleven or twelve years to complete the replacement of deciduous teeth. But the growth rate of the upper and lower jaws is different: The development of the maxilla may stop when one is about 10 years old, while the development of the mandible will continue until about 20 years old.
Therefore, if the reverse jaw is not corrected in time, the lower anterior teeth will restrict the growth of the maxilla when the maxilla is developing rapidly, and in turn, the growth of the maxilla will stimulate the overdevelopment of the mandible. Often when the teeth of a teenager are replaced, the only thing that can be improved is the movement of the teeth, and the impact on the bones becomes more and more difficult. This is why some children have facial problems that are not so obvious when they are young, but the more they grow up, they find that the facial shape is more wrong.
Of course, if early orthodontic treatment is carried out, there is also the possibility of recurrence. For example, the treatment in the mild teeth period has a very good effect, but in the period of dental transition or permanent teeth, reverse jaws appear again. But even so, doctors also generally recommend that the orthodontic treatment should be done early for the reverse jaw in the mild teeth period. The earlier the intervention, the smaller the impact on the normal development of the jaws, and the correction of the deciduous teeth can also have a positive effect on preventing permanent teeth from the problem.
In short, the treatment for reverse jaw is a protracted battle, and it may take several stages of treatment to resolve the problem.
