Teeth are tightly connected to the alveolar bone with the help of periodontal membrane. Under normal circumstances, the connection is firm and there is no noticeable loosening of teeth. However, when periodontal tissues are diseased, the roots are absorbed and shortened, or the teeth are damaged by external forces, the mobility of teeth exceeds the normal physiological range (0.02mm), which is called loose teeth.
Common in periodontitis, dental trauma, apical periodontitis, and mandibular osteomyelitis. In addition, deciduous teeth may also become loose during the transition from deciduous to permanent teeth; when female hormone levels change, such as during pregnancy and menstruation, the phenomenon of tooth loosening may also increase.
