Anterior crossbite and mobile lower central incisors in a 7-year-old patient: a case report.

Anterior crossbite, a permanent upper central or lateral incisor occluding lingually to an opposing tooth, can have serious dental health implications if left untreated. It usually becomes evident in the early mixed dentition, and all general dental practitioners should be aware of the condition and know how to manage it in order to prevent the possibly serious consequences.
