I feel for you. I've had the same problem...I hesitate to talk to people. Im not sure if its my tonsils, adenoids. teeth or sinuses but it is foul. At times it smells like really bad morning breath at other times it smells like feces. I'm thinking your problem which may also be my problem is post nasal drip. I did start taking some supplements and purchased a colloidal nasal spray and the morning type breath disappeared...not sure how long it lasts cause at night i can smell it again. Ive purchased all of the different types of mouthwashes and can say that i have had some success from BreathRX but as i stated it's usually temporary...which i guess is better than nothing. I would still try some of the suggestions here because everyones problem is unique and what may work for some may not work for others. I also read somewhere that you can take Colloidal Silver and hold it over the tooth or in your case the empty socket and that helps. So to condense my suggestions: Colloidal Silver use it to drink and put it in a nasal spray, BreathRX mouthwash and toothpaste, chlorella,and the always tried and supposedly true and least expensive remedies is gargle with peroxide and water or salt water.
