@MrHanky, i happy for you. also had chronic bb for 20 year plus but, recently after series of experimentation a combination of less than $10 natural is currently working for me, has reduced by bb from 95% to 3% in less than 2 week prior application.And kill most of the vsc bacteria which create sour mouth & bb within minute after brushing.
Fortunately, for me i did not much money because i quickly notice the get-rich scherme with the so-called breath specialist and their product's which are mean't to only cover bad breath.
i think doctor's are the last people to trust when it comes to bad breath. From the list of product's on physical store & online you agree with me that they know little or nothing about bad breath. it's just a guess work or experiementation with patient in order to get the proper idea.
