Please google " dysgeusia"( altered taste), you probably can get detailed information. Factors associated with dysgeusia: gingivitis or periodontitis, chorda tympani injury, drugs, especially antibiotics, endocrine disease, heavy-metal intoxication,psychologic problems, zinc deficiency, idiopathic condition.Foul saliva is commonly associated with tooth cavities and periodontitis, or ill fitting prosthesis.
I have the exact same symptoms as you have described. It has been a couple months now. ENT doctor doesn't seem to be of any help. I too am concerned. Have you been able to figure what it is or any treatments that worked? Any help would be greatly appreciated. Thanks.
I've had this for about 20 years! It started, I think, with a really bad throat infection I had when I was young, and ever since then the back of my tongue smells bad, but the tip and front area are fine.
I believe the smell is related to tonsilloliths. I take care to clean out all the crevasses in the back of my mouth OFTEN, but it doesn't really help much at all except to remove tonsilloliths from ever forming.
My thinking is that it is these tonsillar crypts or crevasses that are allowing bacteria and food particles to lodge themselves into and thus emit the odour and taint the smell of my saliva and tongue. Wikipedia has a good article on tonsoliths and even shows a gross picture of one lodged in the back of the mouth crevass.
The only way to completely prevent the smell, I BELIEVE, is getting your tonsils removed. ugh
Until then, you kind of have to live with it and be vigilent about constantly cleaning your mouth -- but your saliva and back of your tongue will probably always have a slight odd odour.
Could it also be something called post-nasal drip? I have breath problems too and am considering buying one of those irrigation systems that flushes out the mucousy crap that gets stuck in the back of my throat, causing my tongue to taste sour.
I have the same problem. I brush my teeth and tongue at least 3 times a day. I also rinse frequently. 30 minutes later I have bad taste in my mouth again. I drink a lot of water and other liquids but doesn't seems to help. I constantly chew gum to cover up and helps produce saliva. I spent a lot of money on 24 hr fresh mouth products and that only seems to last a few hrs for me. Any advise is greatly appreciate.
I heard post nasal drip can be a common cause but I was wondering some people don't actually clean their tongue and it builds up stuff there I take a piece of floss and run it up and down tongue and clean it with tongue scraper it makes a difference in the taste and smell also once in a while using hydrogen peroxide deluted in some water you swish with that helps to get rid of germs.I also drink water before I go to sleep.I hope that helps.
