Wisdom Teeth--Can they be causing bad breath?

A year ago I had my upper and lower left wisdom teeth pulled because they had pus coming from them and made my breath smell really bad and left this gross taste in my mouth. A year later, the smell and taste is back. I still have my upper and lower right wisdom teeth. I was thinking this was the problem, which it may be but when I touch my gum where my upper left wisdom tooth was, it smells extremely bad. Is it possible that something is draining from it causing me bad breath? Please help.

It can definitely be a cause of bad breath, especially if you can isolate the bad smell to some degree.  Try to clean the area as much as you can with brushing, flossing and a mouth rinse.  I would suggest seeing a dentist to evaluate the tooth/teeth to make sure it doesn't become infected (or isn't currently infected).  It would be better to take care of it as soon as possible before any other symptoms start such as swelling, pain, etc.

I don't have a bad breath if I talk. It only comes on if I eat or drink. What could be causing this. Its embarassing.
