“烂牙”也叫病灶牙,是指感染的牙齿或牙龈。病牙里存在大量致病菌及毒素,不仅可致牙龈炎、根尖炎、根周脓肿,还可以在人的抵抗力下降时,随着血液循环和淋巴系统扩散到其它组织和器官,使其它组织和器官产生变态反应、感染、中毒或诱发疾病。 Rotten teeth, also called diseased teeth, refer to infected teeth or gums. There are a large number of pathogenic bacteria and toxins in the diseased teeth, which not only cause gingivitis, apical inflammation, root abscess, but also reduce the resistance of human beings as the blood circulation and lymphatic system spread to other tissues and organs. Other tissues and organs produce allergy, infection, poisoning or disease.
