The reason for flesh growing in the middle of a rotten tooth and frequent bleeding

The reasons for肉 (tissue) growth and frequent bleeding in the middle of a烂牙 (decayed tooth) are usually related to pulp polyps, gingival polyps, or periodontal membrane polyps. These polyps may form when dental caries are not treated promptly, allowing bacteria to invade the pulp cavity or periodontal tissues, leading to inflammation and hyperplasia. Among these, pulp polyps commonly occur in adolescents; due to the rich blood supply of the pulp, chronic inflammatory stimulation leads to hyperplastic changes that protrude from the carious cavity and bleed easily. Gingival polyps may result from long-term food impaction and irritation from rough edges of carious lesions, causing abnormal hyperplasia of the gingival papilla. Additionally, periodontal membrane polyps usually occur during the progression of caries in multi-rooted teeth, where destruction of the pulp chamber floor causes reactive hyperplasia of the periodontal membrane forming a polyp. These polyps not only affect aesthetics but may also cause symptoms such as pain and bleeding, necessitating timely medical treatment. Treatment options typically include polypectomy, root canal treatment, or tooth extraction, with the specific plan determined according to the individual condition.
