I feel like I have this really bad scent and I don't know what it is. I brush my teeth twice a day, sometimes 3 times, I use mouthwash. I gargle to swish, but a few hours later I get the same result. That weird feeling that I have a bad scent in the back of my throat. How do I get rid of this?! My throat doesn't hurt or anything. I feel fine but I don't know what this is. Should i be concerned and please, if anyone knows, tell me how to get rid of the scent and feeling!
