The function of human oral epithelial cells is to withstand friction and prevent foreign bodies from entering, which can play a protective role.

Human oral epithelial cells refer to the densely arranged epithelial cells on both sides of the narrow part of the oral cavity and a small amount of intercellular matrix, which belong to a type of epithelial cells. The surface is covered with mucosa, which can prevent bacteria, viruses, mycoplasma, and other pathogenic microorganisms from invading the submucosa under the oral mucosa. They are indispensable epithelial cells in the human oral cavity, capable of effectively reducing the incidence of oral diseases and digestive system diseases, and play a crucial role in maintaining health.

It is necessary to develop the habit of brushing teeth in the morning and evening and rinsing the mouth after meals to maintain oral hygiene and prevent damage to oral epithelial cells.
