1, congenital mass element
Congenital tooth development deformity, which is characterized by poor arrangement of teeth in adolescence;
2. Long-term tooth loss
Long-term tooth loss will cause adjacent teeth to collapse and form too large tooth gap;
3. Severe dental caries
Tooth decay, a gap formed after bacteria corrode teeth;
4. Periodontal disease
Periodontal disease can lead to the absorption of gum and alveolar bone. The longer the time, the more obvious the root exposure and the larger the teeth gap.
The most important group-periodontitis
Among the four factors of appeal, periodontal disease is the most important reason.
Normal and healthy gums
Normal and healthy gums, full gums between teeth. From the picture, you will see that there are still some small gaps, but they are well supported by gums and periodontal tissues.
Gingiva of periodontitis patients
The gingival condition of periodontitis patients is characterized by a large gap between teeth, swelling and atrophy of gums, and exposure of root. From the picture, the gingival and periodontal tissues have obvious atrophy and bone absorption is also very obvious.
