Yeah, emphasis on "plain". It's proposed as an addition, not an alternative, to conventonal tooth brushing.

Streptococcus salivarius M18 seems also interesting, but its results in preventing caries are much more limited, from what I can tell. It also has be taken continuously (once per day), instead being a one-time application like BCS3-L1.
