Pharyngitis, glossitis, gingivitis

The oral mucosa is a covering organ that separates the interior of the oral cavity from the submucosal organs. The function of the oral membrane is to protect the submucosal organs and to receive and deliver stimuli from the external environment. As the mouth is the portal of the digestive system, it is responsible for chewing, language and other functions. Therefore, the oral mucosa is susceptible to mechanical, chemical and bacterial direct damage, and often causes mucosal erosion. In addition, some systemic systemic diseases have oral mucosal damage at an early stage. Different names are given clinically according to the scope and location of the lesion. If the lesion spreads to multiple mucous membranes in the oral cavity, it is called stomatitis, those who only invade the gingival mucosa are called gingivitis, and those who are manifested on the tongue mucosa are called glossitis.
