Revolutionizing oral health with BLISS: a biofluorescence-led approach to chronic disease management

Dental caries and periodontal disease are the two most prevalent chronic conditions in the oral cavity. These diseases develop early in life and persist throughout a person’s lifetime, often exacerbating systemic health conditions and diminishing overall quality of life. Traditionally, dental care has focused on treating symptoms after they appear, with radiographic imaging as the primary diagnostic tool. However, such methods detect damage only after it occurs, offering limited insight into disease origin. 

 The true culprit behind these conditions is pathogenic biofilm — a structured bacterial community that forms on oral surfaces. Understanding its location and extent is critical for managing disease proactively. Disclosing solutions have long been used to visualize plaque, but they bind to proteins nonspecifically and do not differentiate between harmless and pathogenic bacteria. Additionally, their use can be time-consuming and uncomfortable for patients. 

Our solution is BLISS (Biofluorescence-Led Intelligent Screening System), a non-invasive imaging technology that visualizes biofilm in real time by detecting its natural fluorescence. Pathogenic bacteria, especially late colonizers, produce a metabolic byproduct called porphyrin. When exposed to 405nm blue light, porphyrins absorb energy and emit red fluorescence, while healthy tooth surfaces fluoresce green. This allows clinicians to distinguish harmful biofilm without the need for dyes or rinses.  

Notably, pathogenic biofilm typically forms after 3 days of plaque accumulation and is associated with both caries and periodontal disease. BLISS can detect this early, enabling personalized hygiene feedback and better preventive care. The technology is especially useful around implants, where peri-implantitis often involves biofilm hidden between threads or in deep pockets — areas not visible with radiographs. In these cases, BLISS can confirm whether biofilm removal is complete after treatment.  

Being radiation-free, BLISS is safe for use in various settings such as clinics, schools, elder care facilities, and even at home. Its portability and ease of use support routine hygiene checks without requiring specialized infrastructure. This expands the scope of dental care from reactive treatment to proactive disease prevention and long-term health maintenance. 

BLISS also serves as a powerful communication tool. Patients can see their own oral condition in real time, which fosters trust, improves compliance, and boosts motivation for home care. Clinicians report higher treatment acceptance and return rates when using BLISS, benefiting dentists, hygienists, and patients alike. 

Incorporating BLISS alongside traditional radiography allows for earlier, more accurate diagnosis of chronic oral diseases. This integration marks a shift from symptom-driven intervention to evidence-based prevention. By visualizing what was once invisible, BLISS empowers both professionals and patients to work together toward lifelong oral health.
