Hello I am new here...I am 4 days post-op and I have experienced bad breath as well, what has worked for me is to brush my teeth 3 times a day and also make sure you are drinking your liquid diet on time...mine is every 2 hours and in between 4-6oz of water, that also avoids the bad breath. What I can not stand is the air that goes down my stomach every time I swallow, it makes me want to throw up sometimes
