Plaque accumulated on the tooth surface near the gingival margin for a long time is the initiating factor of chronic gingivitis. Other factors such as calculus, food impaction, and bad restorations can promote the accumulation of plaque and cause or aggravate gingivitis.
Alveolar process type alveolar process disease starts from the alveolar process to destroy the bone. In severe cases, the teeth are completely buried in the soft tissue, and the teeth are loose, falling off, gum bleeding and so on. Some bone destruction is extensive, the edge is indistinct, similar to the change of malignant tumor.
Gingival swelling is mainly caused by local inflammation, mechanical damage and vitamin C deficiency, which is the root pain of teeth and the swelling of the surrounding tooth flesh.
Pharyngitis, glossitis and gingivitis are the covered organs, which separate the inner part of the mouth from the submucous organs. The function of oral membrane is to protect submucous organs and to receive and transmit stimulation from the external environment. Because the mouth is the gateway of digestive system, which undertakes chewing, language and other functions, the oral mucosa is vulnerable to mechanical, chemical and bacterial direct damage, often producing mucosal erosion. In addition, some systemic diseases appear oral mucosa damage in the early stage. Clinically, different names are given according to the scope and location of the lesions. If the lesion involves multiple mucous membranes in the mouth, it is called stomatitis. If it only invades the gum mucous membrane, it is called gingivitis. If it appears on the tongue mucous membrane, it is called glossitis.
The development of human teeth with abnormal teeth is a complex and long process. In this long process, various adverse factors inside and outside the body affect tooth development
