Cofounder at Bristle here. In short, we found that analyzing the oral microbiome from a simple at-home saliva-based test is 88.32% accurate at diagnosing gum disease (even when we ignore severity of disease). We're working on improving the accuracy through improvements in our bioinformatics and data pipelines. With ~47% of Americans over 30 having some form of gum disease, we're hoping this data helps to improve methods of preventing gum disease beyond the failing dogma of "brush and floss more"
