Malaligned teeth, commonly known as crooked teeth are ill spaced or crowded teeth, primarily caused due to a deficiency in the space available in the jaws to accomodate all teeth. Consequently , teeth tend to overlap each other, rather than follow a gentle, symmetrical, pleasing curve. The cause most often is early decay and shedding of the milk teeth which cause the neighbouring teeth to shorten the space for the permanent tooth. Oral disfigurement & consequent conscious inhibited smiling are the perils of such a condition & their correction is the only remedy.
