I am getting bad smell from my mouth daily. I consulted an ENT doctor, he told me that issue is due to bad breath/sinus. And he advised me to do a sinus surgery to prevent bad smell, I had a surgery 1 year back but I dont feel any improvement, still the bad smell is coming.
Today I consulted an another ENT doctor , he is telling me to do a tonsil surgery. I don't know whether I should do the tonsil surgery or not.
Please advise me with the detail.
