Will a baby's underbite correct itself naturally?

　　Under normal circumstances, "di bao tian" refers to reverse bite (underbite). Babies with reverse bite usually will not improve naturally, but the condition can be gradually improved through timely intervention. The detailed explanation is as follows:

　　The formation of reverse bite mainly includes genetic factors and acquired factors, such as improper feeding posture and不良 oral habits like finger sucking and biting the upper lip. Dental and jaw developmental problems caused by these factors generally will not improve with age. If not treated promptly, the condition may worsen as the child grows, not only affecting facial aesthetics, but also potentially leading to decreased chewing function, impaired digestion and absorption, and consequently affecting overall health. It may also cause speech problems and have negative effects on the child's psychological well-being.

　　Once reverse bite is detected in a baby, it is recommended to promptly take the child to the dental department or orthodontic department of a reputable hospital. The doctor will evaluate the child's specific condition and provide appropriate intervention at the right time. For example, during the primary dentition stage, removable orthodontic appliances may be used to guide the normal development of teeth and jaws.

　　In daily life, prolonged bottle feeding should be avoided, and不良 habits such as finger sucking and biting the upper lip should be corrected.
