Recent advances in sequencing technologies, systems biology, and computational modeling have significantly improved understanding of the oral microbiome. Under healthy conditions, the oral microbiome exists in a benign and balanced relationship with host tissues. However, shifts in this microbial community (dysbiosis) are a key aetiological factor underpinning gingivitis. If left unresolved, gingivitis can progress to periodontitis, and result in tooth loss; furthermore, periodontitis has been associated with systemic conditions including diabetes, cardiovascular disease, and cerebrovascular disease. 

Clearer differentiation between health-associated and disease-associated microbial communities is now possible, and research is beginning to elucidate the pathways that govern microbial balance and stability. While interest in microbiome modulation through everyday consumer products is increasing, most oral care approaches remain focused on broad-spectrum antimicrobial activity rather than selectively supporting beneficial microbial communities. This gap creates an opportunity to develop targeted strategies with the potential to guide the oral microbiome toward a healthier and more resilient state.
