I am suffering from halitosis, since last 1 year, I am conversing tonsil stones coming out some times but bad breath is persistent for 24 hours I am brushing my teeth and gargling lots of time in a day, I cannot talk to anybody because of this, I feel that I have a big tins stone in oropharynx which is not coming out, last time before 3 years one very big tonsil stone came out of oropharynx and from then breath was fine. Can anybody check deep if there is any such stone is present and if yes to remove.
