A new review of research suggests that bacteriophages, viruses that infect and kill bacteria, may offer a new way to prevent and treat dental cavities. Cavities are caused by bacteria like Streptococcus mutans that form plaque and produce acid that damages teeth. Current treatments rely on antibiotics or fluoride, but these can harm helpful mouth bacteria or lead to resistance.
The review looked at several phage-based approaches, including phages called φAPCM01, SMHBZ8, and Av-1, as well as enzymes produced by phages. These phages target cavity-causing bacteria directly, breaking them open (lysis) or breaking down the sticky biofilm they create. This could allow for a more targeted treatment that spares the rest of the mouth's microbiome.
It is important to note that this is a review of early laboratory research, not a clinical trial in people. No safety data or side effects were reported, and the studies were not done in patients. The findings provide a theoretical foundation for future treatments, but much more research is needed before phages could become a cavity treatment.
For now, the best way to prevent cavities remains brushing with fluoride toothpaste, flossing, and regular dental visits. This research is a promising step, but it is not ready for your dentist's office.
