Orthodontic issues often arise from heredity conditions. A child whose parent has an underbite will often have an underbite issue himself. Children may have crowded teeth or have too much space between the teeth. They also may have protruding or missing teeth. In some cases, they may have extra teeth or abnormal jaw growth.
Orthodontic issues may be a result of excessive thumb-sucking, early or late loss of baby teeth. Mouth breathing and abnormal swallowing may also require orthodontic treatment.
Other issues that require treatments are poor dental hygiene, poor nutrition, and accidents where damage to the face occurred. Most of the above can be treated by an orthodontist.
