MMS is an excellent anti-bacterial agent. However... I would urge you not to skimp or gamble with Antibiotics and tooth infection. Because there is always the possibility that the Miracle-Mineral-Supplement does not impact the entire strain of infection which could in turn lead to a serious secondary infection after all is said and done.
PS. Tooth infections can easily lead to life threatening conditions. Take it from someone who knows! it's not worth the risks. Grab a good probiotics, stay the course and do all you can to clobber that infection.
