B. dentium is a source of anaerobic infections, and is also tracked in polluted water to trace the source of fecal contamination. Scientists have shown that B. dentium can cause tooth decay in humans. Due to its high tolerance of the acidic environments reached by the human mouth (pH 4.5), B. dentium can sustain growth in the oral cavities, cause harm to the teeth, and break down sugars.
B. dentium has been identified by researchers at Baylor College of Medicine and Texas Children's Hospital as producing a neurotransmitter that may play a role in preventing or treating inflammatory bowel diseases such as Crohn's disease.
