I thought tooth decay was the cause, so me and my best friend went to the clinic
to pull those things out. But I was wrong to my conclusion cause the unpleasant odor still remains. we did jugging during our free time, it helps a little but the odor keeps coming back..I'm thinking I was the carrier of a kind of desease, cause i observed my bestfriend aquire bad breath every time, after we stay together for few hours. I know its in me.
