In brief: Many causes/sites
Bad breath can have GI cause, as simple as what food's eaten.
Bowel blockage, lesions can cause odor. A physician can evaluate. If a tooth is decaying, it might have a persistent odor. That decay can occur even under a crown. A patient should keep asking the dentist or doctor to evaluate if no cause of persistent smell is found. Dental/tongue hygiene is important no matter what cause. See comments.

I agree and if nothing else if found, you might require endoscopy to look down your esophagus and into the stomach and perhaps bronchoscopy into the lungs. There can be infections brewing there that can smell awful. Also one of my patients who had bad breath (called halitosis) actually was found to have a cancer of his esophagus so he was happy he looked into it!

Bad breath can have many causes. From a dental standpoint periodontal disease is a major player as well as dental infections. Ketosis from a all protein diet can also create breathe issues . Many patients can often gain better breathe from simply brushing the tongue.

In brief: Self diagnose it!
Other than common food odors that come from ingesting garlic etc.
Entering the blood and exit the lungs (or rare stomach malignancies) most bad breath comes from the surface of the tongue, ;/or from between the teeth. Floss twice daily. (skipping one day is like not flossing at all). And brush your tongue, with a touch of toothpaste, the farther back the better. Odds on, bad breath reduced!

Studies have shown that it may be better to use a tongue scrapper on your tongue as it removes bacteria where brushing can brush them into the tongue

In brief: Periodontal
Possibly periodontal disease.
Could be infected tonsils. Post nasal drip. A broken rotting tooth. And many more possibilities. Start with a visit to a dentist to see what your oral condition is if it has been a while. Other possibilities are GI related, but it would seem best to rule out your dental, gum and oral health first.

In brief: Floss,scrape,reflux
Could all be reasons for a foul dental odor. First you have to look at your dental hygiene.
Do you brush and floss regularly? If you don't, floss, bacteria gets lodged deep in your gums and your teeth and rots, so to speak. Do you have a white coat of film on your tongue.. Bacteria heaven. Get a tongue scraper, floss, brush, scrape and rinse with Any mouth rinse that has chlorine dioxide (breathRX

In brief: Bad breath
90% of bad breath can come from the bacteria in your tongue-get a tongue scrapper at the drug store and use it daily.
Oolitt is a good brand. Brushing your tongue just brushes the bacteria deeper into your tongue.

In brief: Can be due to a host
Of reasons - limited details offered in question; could be due to -- poor oral hygiene, gum disease; food impacted between teeth, medication effects; and the list goes on.
First step is to consult with a dentist asap for a comprehensive exam, x-rays and cleaning. In the interim, invest in a good mechanical toothbrush (ex: oral b triumph) and a waterpik and use them daily. Hope this helps.

In brief: Dental Abscess
From a dental standpoint, bad breath is directly related to bacteria in the mouth and often infection.
Bacteria can stay in your mouth for extended periods of time in the form of plaque which turns into the hard deposits we refer to as calculus or tartar. You need to have tartar removed by a dental hygienist. When associated with a pimple like infection near a decaying tooth, it may be an abscess.

In brief: Clean better
The tongue collects quite a bit of food, i believe the french used to use a toungue scraper like a butter knife to scrape across the tongue and remove food from the crypts of the tongue.
Brushing your tongue with the tooth brush will work too. Tonsils can also have crypts with a lot of decaying food, have your doctor look for these.
