[|Human|] I have chronic bad breath and I think it is caused by food particles getting caught somewhere behind the uvula  or where my nasal passage meets my throat , not sure,and the food breaks down into a sort of foul smelling paste as it is lodged there out of sight.This horrible smelling paste appears as tiny bits about the size of 1/3 of a rice kernel or smaller . These bits will dislodge and fall down the back of my throat , maybe 3 to for bits  once every 4-6 weeks . I spit them out but I know there is more stuck back there because my breath smells like the broken down food substance I have spit out.I am so mortified frustrated with this disgusting issue ! Thank youThis has been going on for at least 20 years but I was able to mask the foul smell with mints and mouthwash but now the smell is constant.
[|AI|]  Hello and welcome. Thanks for sharing your concern. Since it appears that the foul smell is due to food lodgment and degradation therefore it should be ad Chat Doctor. In my view first please get an endoscopy done. Based upon its report, .it can be decided about the origin of bad breath.Also, your ENT specialist can check if there is any sinusitis, which again causes such problems. Once it is ruled out then you can go for dental check up. Hope it helps. Thanks. Take care.
