If a deciduous tooth is lost prematurely, the adjacent teeth on either side will migrate towards the space of the lost tooth, closing up the space. The reduced space will not allow the succeeding permanent tooth to erupt into good alignment.
• Bad habits
Bad habits such as digit sucking and biting on a pen can induce pressure on the teeth and push them into an abnormal position.
• Development of oral disease due to lack of proper oral care and treatment ：
o Dental caries
Severe dental caries in the adjacent tooth surface will cause the neighbouring tooth to tip over and take up the space, and the teeth will become irregular.
o Periodontal disease
Severe periodontal disease will result in the loss of bone support to the teeth. The teeth will then drift to abnormal positions.
Lots of teeth due to oral diseases (such as dental caries and periodontal disease) or traumatic injury can cause drifting of adjacent teeth.
