Periodontal disease Periodontal disease is prevalent in the population. It is the main reason for tooth loosening. Due to various reasons, the periodontal ligament has been subjected to chronic inflammatory stimulation for a long time, causing the periodontal ligament fibers to be destroyed. In this way, the periodontal ligament is damaged and cannot support the teeth, resulting in loose teeth. External force injury In daily life, due to accidental bruises, falls, etc., the teeth are injured, and some people like to bite hard food or open beer with their teeth, etc., which easily makes the teeth loose. Excessive external force will damage the periodontal ligament, the elastic fibers between the teeth and the periodontal ligament will be affected, and the teeth will become loose. Periodontal Deformation Periodontal Deformation generally occurs in young people. Periodontal deformation is caused by degenerative changes in periodontal tissue. Periodontal fiber damage or alveolar bone resorption occurs, resulting in loose and moving teeth. . Although the probability of occurrence of this disease is low, it is extremely harmful, and it is easy to cause complete tooth loss, so attention should be paid to prevention. Other dental diseases Some oral diseases or systemic diseases can also cause tooth loosening, such as acute apical periodontitis, jaw osteomyelitis, and tumors in the jaw can also cause tooth loosening. Necrotizing gingivitis, vitamin deficiencies, diabetes, etc. can also cause tooth loosening, because these diseases affect the gums and periodontal tissue, resulting in the appearance of tooth loosening. Prevention of loose teeth 1. Correct oral care habits, pay attention to brushing your teeth without too much force, brush your teeth every morning and evening, and the time should not be less than three minutes, and pay attention to cleaning the dirt between the teeth, you can use dental floss to effectively clean up. 2. Wash your teeth regularly. Scaling can remove plaque, calculus, etc. from the teeth, effectively prevent and treat periodontal disease, and can also detect various oral problems as soon as possible, so as to achieve early detection and early treatment. 3. If there is bleeding gums, the gap between the teeth becomes larger, and the occlusion of the upper and lower teeth changes, you should go to the hospital for examination and treatment as soon as possible.
