A soft meat growing in the middle of the teeth may be caused by gingival hyperplasia, caries, periodontal polyps, gum polyps and other factors. 1. Gingival hyperplasia: If affected by local stimuli for a long time, the gum tissue may proliferate, resulting in a soft meat in the middle of the gap between the teeth. 2. Caries: If caries exists, because of long-term chronic inflammation exists, will easily lead to the gap between the middle of the teeth grow a soft meat condition. 3. Periodontal polyp: after the caries damage of multiple teeth penetrates the pulp cavity and destroys the pulp chamber bottom, when the periodontal membrane reacts to the external stimuli, there is hyperplasia, leading to the phenomenon of a soft meat in the middle of the teeth. 4. Gingival polyps: teeth adjacent to the dentinal surface of the caries cavity, the gums will be to the cavity of the formation of polyps, resulting in the middle of the gap between the teeth grow a soft meat. A soft meat in the middle of the gap between the teeth is recommended to go to the hospital in a timely manner, improve the examination to clarify the cause of the disease, and follow the doctor’s instructions for treatment.
