HOSA Dental Terminology Practice

What is the gingiva?

1. The hard tissue of the teeth

2. The soft tissue that surrounds the teeth and alveolar bone

3. The outer layer of the tongue

4. The space between the lips and gums

The correct answer is: The soft tissue that surrounds the teeth and alveolar bone

The gingiva refers to the soft tissue that surrounds the teeth and covers the alveolar bone, playing a critical role in oral health. This tissue, commonly known as the gums, helps protect and support the teeth by providing a seal around them as well as forming the mucosal lining of the oral cavity. Healthy gingiva is essential for preventing periodontal disease, which can lead to tooth loss and other dental issues. Its structure is important because it contains connective tissues and is supported by the underlying bone, thus contributing to the overall stability and health of the dental structures. In contrast, other options refer to different anatomical structures: hard tissue of the teeth pertains to the enamel and dentin, the outer layer of the tongue relates to a completely different area of the oral cavity, and the space between the lips and gums, known as the vestibule, does not encompass the gingiva itself. Understanding the definition and function of the gingiva is fundamental for anyone studying dentistry, as it is a key component of oral anatomy and health.
