If you do nothing about the crowding and/or crooked teeth, there is a good possibility the teeth may stay that way. Other than the compromised appearance of crooked teeth, a person’s bite and chewing can be affected by misaligned teeth. Abnormal wear on the teeth and jaw pain may result. Crowded teeth may cause an adult tooth to become impacted and never grow into the mouth properly. Occasionally, adult teeth may have to be removed to make space to straighten the remaining teeth. Crowded teeth may also be difficult to keep clean. Orthodontic correction at the appropriate age can help guide the adult teeth into the mouth for proper fit, function, and appearance.
