Streptococcus salivarius M18 is a specific type of beneficial bacteria naturally found in the human mouth. This bacterium belongs to a group of microorganisms known as probiotics, which are live microorganisms that offer health benefits when consumed in adequate amounts. It works to support a healthy oral environment, helping maintain the natural balance of microorganisms within the mouth.
Understanding Streptococcus salivarius M18
Streptococcus salivarius M18 is a distinct strain of the Streptococcus salivarius species, identified for its contributions to oral health. It is a common inhabitant of the oral cavity, found in healthy individuals. This bacterium contributes to the diverse community of microorganisms that reside in the mouth, helping maintain the natural microbial balance.
Its Impact on Oral Health
Streptococcus salivarius M18 contributes to oral health through several mechanisms, primarily by inhibiting the growth of harmful bacteria. This strain produces antimicrobial substances called bacteriocins, specifically salivaricin A2 and B, which target common oral pathogens. These bacteriocins are effective against Streptococcus mutans, a bacterium largely responsible for tooth decay, and other bacteria associated with bad breath and gum disease.
The bacterium also aids in reducing plaque formation through the production of enzymes such as dextranase and urease. Dextranase helps break down the sticky dextran polymers that contribute to plaque buildup on tooth surfaces, while urease helps stabilize the pH levels in the mouth. This dual action helps prevent the accumulation of dental plaque and reduce the acidic environment that can lead to tooth decay. Streptococcus salivarius M18 can also support healthy gum tissue by exerting anti-inflammatory effects, helping to reduce inflammation associated with conditions like gingivitis and periodontitis. Its ability to displace odor-producing bacteria also contributes to fresher breath.
Incorporating Streptococcus salivarius M18 into Your Routine
Streptococcus salivarius M18 is commonly available as an oral probiotic supplement. These supplements are often found in forms designed for direct application in the mouth, such as lozenges or powders intended to dissolve slowly. The lozenge form allows the beneficial bacteria to be distributed throughout the oral cavity, promoting direct contact with oral surfaces. For optimal results, these supplements are generally taken after brushing teeth or professional dental cleanings, when the oral flora may be temporarily out of balance.
Safety Profile and Considerations
Streptococcus salivarius M18 is generally considered safe for human consumption due to its natural presence in the oral cavity of healthy individuals. Clinical trials have supported its safety profile. Side effects are rare and typically mild, if they occur at all. As with any supplement, individuals with compromised immune systems or pre-existing medical conditions should consult a healthcare professional before beginning use.
