What is the main characteristic of subgingival biofilm?

The main characteristic of subgingival biofilm is that it resides below the gumline. This area is often a site of significant bacterial accumulation and is important to consider in periodontal health. Subgingival biofilm consists of microorganisms that can lead to periodontal diseases, which are often not visible without specialized dental instruments.

In contrast to biofilms that are found above the gumline, subgingival biofilms are more difficult to access and require professional dental cleaning for effective removal. Daily brushing typically does not reach the areas below the gumline, making it essential for dental professionals to manage this biofilm during dental cleanings. Understanding the location and nature of subgingival biofilm assists dental professionals in forming effective treatment plans and educating patients about the importance of gum health.
