When my taste gets really bad I have a collection of mucus in my lungs. That needs treated. Antibiotics usually take care of that right away. However one can get sores or fungi in the mouth, maybe in the throat. Talk to your Dr. if u can.

Mine reminds me of car exhaust.

I have the same problem. There must be something to do to get rid of it. Cant be me teeth as i have none and i do clean my gums frequantly

Yes, what can be done for it, nothing, just let it go,

I find that sucking on some peppermint candy helps and its helps settle the stomach alittle too.
