Crossbites should be managed as early as possible because early intervention prevents the development of functional mandibular shifts, asymmetrical jaw growth, and complex skeletal deformities. Addressing crossbites in the mixed dentition phase allows for easier correction with minimal orthodontic or surgical intervention. Delayed treatment often leads to worsening malocclusion, facial asymmetry, and temporomandibular joint problems. Early correction promotes normal occlusal development and optimal jaw alignment, reducing the need for extensive procedures later. Therefore, timely management is crucial for effective and less invasive outcomes.
