This works 100%. Instead of doing what the post said, i just used a lime and added some water and rinsed my mouth with that and at the end i used mouth wash, i used listerine but it shouldnt matter. I brush my teeth, i eat, i do the lime and water thing, and then mouthwash, and so far its been working very well but you do have to rinse out the lime and mouthwash well.
Also if you wake up with a white tongue then its probably coming from an unidentified source in your room and you might need to get rid of that first before you start this, but this also works if you do it before you start the day the only thing is that it might not get rid of BB permanently.
I want to revive this post because now i have an explanation to this. So this helps you completely get rid of bad breath/white tongue caused by patm(maybe non-patm related bb too), it doesnt cure patm but only one aspect of it. This works because apple cider vinegar is very acidic, around 2-3 on the ph scale(1-14 1 being most acidic and 14 being most basic), and this is very great at getting rid of patm for some reason, my working theory is that one component of patm is ammonia(11 pH) which is counteracted by an acid, this works because acid and bases counteract each other. I know that low ph solutions get rid of patm because i tested on myself, i only have patm in my hair and i used a lime(one of the most acidic fruits on earth) on my hair and it reduced the intensity of my patm. I think that any acidic solution will help reduce reactions and so this is why apple cider vinegar "cured" the OP's patm, his BB was the sole cause of patm reactions. If you have bad breath/white tongue caused by patm then try this but instead of apple cider vinegar which i heard smells bad, you can use lime or lemons or anything that is edible and very acidic. I would recommend anything within 2-3pH and not anything higher, maybe 3.5pH but it might not be as effective as intended.
Why do you think this works? and how long have you had patm for?
How long have you had success and does it lead to no reactions.
