(1) Tooth jitter can be caused by bumping, falling or excessive occlusion. This is because the periodontal ligament is damaged by excessive external force, and the elastic fiber between the teeth and the periodontal ligament is damaged, which makes the teeth loose.
(2) Tooth loosening caused by periodontal disease. Periodontal membrane is chronically stimulated by inflammation for a long time, and gradually degenerates and destroys periodontal membrane fibers. When these periodontal tissues supporting teeth are gradually destroyed, teeth will become loose.
(3) Periodontal degeneration can lead to loosening of most teeth. Periodontal degeneration mostly occurs in young people because of degenerative changes in periodontal tissue, destruction of periodontal fibers and absorption of alveolar bone, which leads to loosening and displacement of teeth. Tooth loosening caused by periodontal degeneration first occurs in the upper and lower anterior teeth and the first molar. Due to the displacement of teeth, the originally arranged teeth become thinner, and the upper front teeth protrude outward, resulting in gaps between teeth. Periodontal degeneration is rare in clinic, but it is very harmful, which often leads to the early tooth loss of young people and should be paid attention to.
(4) Acute periapical periodontitis, osteomyelitis of jaws and tumors in jaws can all cause tooth loosening. Some diseases that can affect gums and periodontal supporting tissues, such as necrotizing gingivitis, vitamin deficiency, diabetes, etc. It can also lead to loose teeth.
The treatment of tooth looseness should be treated in time according to the cause, and most patients can be cured.
