My tooth smells really bad. My upper back left tooth smells really bad and leaves horrible taste in my mouth. It makes my breath smell bad too. When i floss i can smell it right away. After i brush it covers up the smell but it comes right back.

In brief: "Tooth smells"

Probably infection, either badly infected tooth or badly infected gum/bone around the tooth, or both.
Can also be from lung abscess, GERD, infected tonsils, infected sinuses, etc. Start with your Dentist. If no clear-cut dental cause can be found your Dentist will refer you to the proper Dental or Medical Specialist for further investigation.

Other possibilities include sinus infection or lung infection. The dentist is a good place to start, but if no clear dental reason is found you should consult with your personal physician.

In brief: The

The most likely cause is that there is a cavity between the back tooth and the tooth next to it.
This causes a space to form where food can get caught and that can create the bad smell you mention. I suggest you see your dentist to evaluate the area as soon as possible.
