tooth displacement
Introduction
Introduction When periodontitis develops to a certain extent, the teeth tend to tilt toward the more severely damaged side due to the destruction of the alveolar bone of the fixed teeth.

Cause of tooth displacement
One of the symptoms of periodontitis, the periodontal disease patients with gingiva atrophy, less cementum, the crown fulcrum moves downward, a slight force can move the teeth.

Examination of tooth displacement
If the condition is mild, the alveolar damage is not much, the teeth are not loose, and the teeth can be restored by orthodontic treatment after controlling the periodontitis; if the condition is serious, the alveolar bone damage absorbs more than 1/2 of the length of the root, and the teeth are loose. It is impossible to reset the teeth.

Symptoms of confusing teeth
Abnormal tooth structure: refers to abnormality of tooth development caused by various obstacles during tooth development or matrix calcification during tooth development, and leaving permanent defects or marks on the tooth tissue. Commonly, enamel hypoplasia, dentin dysplasia, dental fluorosis and tetracycline staining teeth.
Large gaps in the teeth: It is because of the poor development of the teeth or the large gap between the teeth caused by the damage of the posterior teeth, which leads to eating teeth or affecting the appearance of the teeth.
Dislocation of the tooth: under the impact of a large violent attack, the tooth may be partially or completely dislocated. Due to the tear of the periodontal membrane, even the neurovascular bundle entering the pulp from the apical foramen also tears, and the tooth is loosened and tilted clinically. Elongation and pain, hinder chewing. When the teeth are completely dislocated, the teeth are separated from the alveolar socket, or only the soft tissue is connected, often accompanied by gingival tears and alveolar bone fractures.
Crowded dentition: The clinical manifestation is that the teeth are crowded and misaligned, mainly because the amount of teeth is larger than the amount of bone, and the shape of the arch is abnormal.
Widening of the teeth: the gums are filled with gingival nipples. In a person's life, the number of gingival papilla necrosis is many, and the height of the gingival nipple will gradually decrease, which makes the teeth gradually widen, which is a sign of human aging. If the gums are not properly cleaned and the gums are often inflamed, it will accelerate the gingival nipple loss, causing periodontitis and widening of the teeth.
Abnormal teeth: The development of human teeth is a complex and lengthy process. In this long process, various unfavorable factors inside and outside the body can cause different types of developmental abnormalities in different stages of tooth development, such as abnormal teeth eruption, abnormal number, abnormal morphology and abnormal tooth structure. X-ray examination is required for late teeth, abnormal roots, fused twins, multiple teeth, ambushed teeth, and dental caries. Patients with suspected congenital syphilis should be aware of the bones in other parts, often requiring X-ray examination.
