The gingiva, commonly known as the gums, is the soft tissue that surrounds and supports the teeth in the mouth. It plays a crucial role in oral health by providing a protective barrier against bacteria and other harmful substances. Healthy gingiva is typically pink and firm, indicating good dental hygiene. Gingiva is an essential part of the periodontium, which includes other structures like the periodontal ligament and alveolar bone. Maintaining healthy gingiva is important to prevent conditions such as gingivitis and periodontitis, which can lead to tooth loss and other health issues if left untreated.
