Periodontal disease (gum disease) is a polymicrobial biofilm infection that breaks down tissue and bone, potentially leading to tooth loss if untreated. This chronic infection starts in the mouth but can spread and often goes undiagnosed. Untreated periodontal disease has been linked to systemic conditions such as digestive disorders, cancer, diabetes, cardiovascular disease, rheumatoid arthritis, and Alzheimer’s. The Feno™ Saliva Test provides patient-specific data to help guide clinically relevant treatment options.
