Children with receding jaws are treated in different ways depending on their age. If the age is less than 4 years old, it can be observed temporarily; if the age is more than 4 years old, it usually needs to be improved by changing bad habits, wearing braces, orthodontics and other methods. 1. Age less than 4 years old: Since children’s jaws are not fully developed, or due to poor development of facial muscles, jaw retraction may only be temporary and can be observed temporarily without special orthodontic treatment. 2. Age over 4 years old: (1) Changing bad habits: Some children like to bite their lower lips for a long time or often like to breathe with their mouths open, these bad habits can lead to the phenomenon of jaw retraction, so parents are advised to correct the children’s bad habits in time. For example, when parents find children biting their lower lips, they should play with them more often to divert their attention, and if they like to breathe with their mouths open, they can adjust their sleeping positions; (2) Wearing orthodontic appliances: functional orthodontic treatment can be used, generally by changing the environment of the facial and jaw muscle groups, promoting occlusal development and craniofacial bone growth so as to achieve the purpose of correction, generally applicable to the growth spurt and growth period of the child; (3) Orthodontic surgery: generally for children with mild or moderate jaw retraction during the permanent teeth period, it is generally recommended to take this way of treatment after all the teeth have erupted, in this case, you must go to a regular hospital and under the guidance of a doctor. In addition for children with more serious jaw retraction, you can wait until adulthood for surgical treatment.
