Frequently asked questions about KFORCE

Is KFORCE Clean Mouthwash the result of genetic engineering?
No. KFORCE Clean Mouthwash is entirely natural. It is not a manufactured chemical, or genetically modified in any way.  It is a course of powdered mouthwash that contain beneficial bacteria that are naturally carried by about 10% of the population.  It is a way of passing the benefits of those bacteria to people who do not have them.   

How are the bacteria in BLIS K12 Throat Guard kept alive?
The bacteria in KFORCE Clean Mouthwash are freeze dried and then incorporated into a powder format

Are there any side-effects from using KFORCE Clean Mouthwash?
After extensive research, there have been no significant side-effects reported.  This BLIS-producing strain is a naturally occurring bacterium that is carried in a small percentage of the population.  It is not a manufactured chemical and it has not been genetically modified in any way.

Are there likely to be any allergic reactions from KFORCE Clean Mouthwash?People who are immune compromised should seek the advice of their doctor before using KFORCE Clean Mouthwash.

How effective is the bacteria in KFORCE Clean Mouthwash ?
Below is a scientific experiment to show the effectiveness of Streptococcus salivarius K12. A strain of Streptococcus salivarius K12 is grown vertically on an agar plate. Then nine indicator strains of bacteria labelled I1 to I9 are grown horizontally across the same agar plate and incubated for 18 hours. The inhibition area from the S. salivarius K12 can clearly be seen.

Why do you need to wait 2 hours after taking the chlorhexidine mouthwash?Chlorhexidine is a very effective antibacterial and is particularly useful against oral bacteria.  It adheres to the surface of the mouth and has been found to display antibacterial activity for up to 2 hours after being used in the mouth. If you take the KFORCE Clean Mouthwash too early you will increase the percentage initially killed off.

Will taking chlorhexidine on the second day kill off the K12 from the previous day/s?
The chlorhexidine will only kill off a percentage of the bacteria.  While it does kill off some of the K12 on the second day the overall effect is a cumulative increase over the two days.

What percentage of the population naturally has these strains of bacteria?
Most healthy people have S. salivarius strains in their mouths. S. salivarius is a naturally occurring bacterium, a predominant inhabitant of the dorsum of the tongue and the pharyngeal mucosa in humans. S. salivarius becomes established in the human oral cavity within two days after birth. The levels of S. salivarius in swab samples taken from newborn infants represent 10% of the total streptococci isolated, increasing to 25-30 % by one month of age. In adults, S. salivarius represent 17% of the total streptococci isolated from the tongue and 30% from the pharynx.

However only 10% of the population have BLIS-producing strains of S. salivarius.  KFORCE Clean Mouthwash contains BLIS-producing Streptococcus salivarius K12 which produces two types of BLIS, Salivaricin A and Salivaricin B. Strains that produce both these types of BLIS exist naturally in around 2% of the population. 

Another interesting fact is that Streptococcus salivarius is closely related (up to 99% matching) to Streptococcus thermophilus which is widely used in yoghurt and cheese manufacture.
