I so understand your problem. However, I had very persistent bad breath before I did the operation so I am not too freaked because I had it anyway.
But yeah I know what you mean.
I think it comes from 2 things:
not being able to brush the very back of the tongue where food particles collects. teeth can be brushed just fine though.
And the scabs. Now do not go poking the scabs they are meant to be there. Mine are starting to fall off but still there.
I think we are meant to have this bad breath for 10-14 days until the scabs fall off. When the scabs go completely then your breath should be normal again.
I am just hoping my breath does not return to what it was like pre op because it was terrible before.
Here's to hoping the op will make my breath better.
Btw. my op was Nov 2. So hang in there.
