Are the spirochetes present in mouth pathogen?

Answer 1

Spirochetes, particularly Treponema denticola, are present in the oral cavity and can be associated with periodontal disease. While not all spirochetes are pathogenic, their presence is often linked to oral infections and inflammation, especially in individuals with poor oral hygiene. They can contribute to the complex microbiota of the mouth, potentially exacerbating periodontal conditions. Therefore, while they can be part of a healthy oral microbiome, certain species may pose a pathogenic risk under specific circumstances.
