Okay, so ive been having breath problems for a few years now. No one tells me but i know its really bad, and it makes me come across as anti social and unfriendly, when really i just dont want people to smell it. I have IBS, dont know if thats the problem though. I had a dentist appointment a few days ago and my teeth and gums are healthy etc, i brush twice a day with an electric toothbrush, floss and clean my tongue and after 15 minutes or so it smells. i thought it might be post nasal drip because i am always clearing my throat and it feels like there is mucus there. I also read about tonsil stones but i cant see any there (i checked with a light) but there is a horrible taste coming from the back of my mouth.I have considered going to the GP now because i am sick of this problem and think it could be something not relating to my mouth, sorry for going on guys but i want advice because i am sick of chewing gum and want to approach people, many thanks guys.
