Oral structures refer to the various parts of the mouth that play essential roles in functions like eating, speaking, and breathing. Key components include the lips, tongue, teeth, gums, and palate. Each of these structures contributes to the overall health and functionality of the mouth. The tongue aids in tasting and manipulating food, while the teeth are crucial for biting and chewing. The gums support the teeth, and the palate forms the roof of the mouth, separating the oral cavity from the nasal cavity. Together, these structures ensure proper oral function and hygiene.
