Anybody who has had badbreath for along time knows how bad chlorine dioxide is.It works for a short period of time then your badbreath comes back worse.It is considered a carcinigenic, just imagine if you swallowed it, The reason it works at the begining for bacterial infections is because they are transient bacteria, bo and bb are an overgrowth of resisdent bacteria.Same reason it works for cancer and aids they are viruses and not resisdent in your body.Thats why so mant people can not get rid of there bb or bo.You have to reverse the bacterial population so more friendly resident bacteria are able to trive and compete for the food vrs the unfriendly resident bacteria.believe me its not as easy as just taking probiotics
