Overdevelopment of the alveolar bone may be related to daily bad habits, malocclusion or genetic factors, which need to be judged according to the oral and general conditions. 1. Bad habits. If bad habits such as finger sucking, lip licking, lip biting, etc. occur frequently during growth and development, it will stimulate the overdevelopment of the alveolar bone in the upper or lower jaw, which will cause facial abnormalities or misalignment of teeth. 2. Malocclusion. During the period of jaw growth and development, if the order of tooth replacement is abnormal or there are multiple teeth, abnormal eruption of teeth and other conditions resulting in malocclusion, it will also stimulate the overdevelopment of the alveolar bone. 3. Genetic factors. Alveolar bone overdevelopment is also related to genetic factors, if there is a family of abnormal development of the upper and lower jaw, their offspring may also have abnormal jaw development. Overdevelopment of the alveolar bone is related to a number of factors, it is recommended to go to the hospital to determine the specific examination.
