The oral cavity is the anatomical region encompassing the mouth and its various structures. It includes the lips, teeth, tongue, gums, and the hard and soft palates. The oral cavity serves multiple essential functions, such as the initial processing of food through chewing, the formation of speech sounds, and the initiation of the digestive process through the secretion of saliva. Additionally, the oral cavity plays a role in taste perception and is a gateway for both respiratory and digestive systems. Regular oral hygiene practices, including brushing, flossing, and regular dental care, are crucial for maintaining oral health and preventing oral diseases.
