DoctorSaliva Insight
This organism is commonly found in healthy oral environments and is usually not harmful. Balance matters because even commensal bacteria can contribute to problems if the overall microbial ecosystem becomes disrupted.
Where It Lives
Tongue, saliva, dental plaque
What It Does in the Mouth
Metabolizes lactic acid produced by other bacteria, helping to neutralize acid in the mouth. Generally protective against cavities in balanced amounts.
