The distances between teeth may occur with the continuous abnormal growth of the jaws. Missing teeth can cause the surrounding teeth to move, due to the extra space, creating gaps between the teeth. Problems with too much space and distances between teeth can lead to problems with gums (due to lack of protection offered by teeth), periodontal bags and increased risk of periodontal disease.
Teeth overcrowding occurs when there is not enough space inside the jaw for all the teeth to fit normally. When left untreated, the condition of highly crowded teeth can worsen over time, leading to very crooked teeth. This condition can lead to plaque buildup, tooth decay and increased chances of gum disease.
An overbite occurs when the upper teeth overlap the lower teeth. This usually has genetic causes. It is also caused by bad oral habits or over-development of the bone that supports the teeth. This can lead to problems with the gums, irritation and /or damage of the lower teeth and can cause painful problems of the jaws and maxillary joints.
Open bite often occurs when some teeth fail to have physical contact with their opposing teeth, for proper biting. Most often, it is caused by an abnormal genetic structure of the jaw or excessive sucking of the thumb. An open bite can cause defective or painful chewing and even speech dysfunction. This can also lead to larger problems such as thermo-mandibular joint (TMJ) disorder.
Sub-bite may occur when lower teeth overlap the upper frontal teeth. It is usually caused by lower growth of the upper jaw, higher growth of the lower jaw, or both. It can also be caused by the total lack of upper teeth. This can prevent the normal functioning of the frontal teeth or molars, which can lead to tooth ageing. It can also cause painful problems of the jaw and maxillary joints.
