for anyone with fecal or dying smell please read

i too had the same exact promblem i did everything all my wisdoms, mri of sinus .the smell was so bad i was ashamed to go to the doctors it started from a dead smell to a fecal smell .ive been going thru this for 3 years i finally found out whats wrong i went to numerous doctors ,researched on the internet.my promblem is the pulp inside of my teeth is dying therefore it breaks down into disharge wwich goes out the root of the teeth into my sinus thats why im congested like a cold an cant smell.the dentist kept telling me nothings wrong with the tooth cause nothing was wrong with the outside.when teeth dye they turn black or they can be real yellow in the middle.if you take medicine your body will discharge all the mucas out thats why when you have a bowel movement the smell lessons but your sinus production starts it back up again so the smell comes back.if you get your teeth pulled you have to do Antibiotic when your teeth is almost closed because the infection from your sinus and teeth drains down in your mouth into your open socket therefore infecting the socket. along with Antibiotics you need a nasal steriod this is for the smell in your sinus because you have had the infection so long your sinus keeps producing the mucas smell this is to stop that production out of your sinus intil your normal smell returns because your post nasal drip will have the same smell making your mouth smell and you think its still there.this is my story i dont know about anyone else but i hope it helps i would get 2 mirrors one real small and look in your mouth for any brite yellow spots on your teeth sometimes it can be under a filling see if there is any spot the filling doest cover is there a hole is it black.when you eat the smell is more strong cause your chewing on the teeth and your sinus are opening that why you can smell it better .also another way to tell is if you take medicine a couple hours after do you get chills or hot like your body is fighting a infection.plus sometime when you have a infection in the teeth you can get a bump or nudles in the mouth this is from the infection needing somewhere to drain so it forms pockets theseare called gumboils you can bust it but i dont think you should cause this will make the smell stronger cause the pus will drain out into your mouth.i hope this helps someone and i would like feedback good or bad thanks!
