What role does keratinized gingiva play in oral health?

Keratinized gingiva plays a crucial role in oral health by acting as a barrier to pathogens. This specialized tissue, which is tougher and more resistant to abrasion than non-keratinized tissue, is instrumental in protecting the underlying structures of the periodontal tissues from microbial invasion and damage. The keratin layer offers a physical barrier against bacteria and other harmful substances that can cause periodontal disease.

Moreover, the health of keratinized gingiva is essential for maintaining the integrity of the oral mucosa. If the keratinized gingiva is compromised, it can lead to inflammation or infection, which may contribute to various dental issues, including gingivitis and periodontitis. Thus, this protective function is vital for maintaining overall oral health and preventing disease.
