What is the optimal age for orthodontic treatment of a child's underbite?

Under normal circumstances, "underbite" refers to malocclusion with reverse overjet. There is no definitive best age for orthodontic treatment of children with reverse overjet; however, the period between 10 and 16 years of age is generally considered most suitable. The detailed explanation is as follows:

The age range of 10 to 16 years is a critical period for children's growth and development, during which teeth and jawbones are relatively malleable. Orthodontic treatment at this stage can more effectively adjust the position of teeth and jaws, aligning the teeth properly and improving symptoms of reverse overjet. Moreover, during this period, permanent teeth gradually replace primary teeth, and the development of teeth and jawbones becomes increasingly stable. Performing orthodontics at this time allows full utilization of the developmental potential after the completion of permanent tooth eruption, resulting in more stable and long-lasting treatment outcomes. In addition, children aged 10 to 16 usually possess adequate cooperation and comprehension skills, enabling them to better follow the dentist’s diagnosis and treatment plan, thus ensuring smooth progress throughout the correction process.

If needed, it is recommended to visit a reputable hospital and undergo the above procedures under the guidance of a qualified medical professional to improve dental alignment and jaw positioning, thereby ensuring the child's oral health and aesthetic appearance.
