When teeth are extracted, bad breath is to be expected especially if the tooth gets infected. It usually clears up as the infection drains out and the site heals. Normal post-extraction bad breath can be eliminated by rinsing the mouth several times a day with a solution of 1 teaspoon salt to 1 cup of warm water, according to WebMD.

Bad breath can also be a sign of a dry socket, which happens when a blood clot fails to form in the extraction site. Bad breath from a dry socket is accompanied by other symptoms, such as pain radiating into the eye or ear, a bad taste in the mouth, visible bone in the socket, and swollen lymph nodes. According to WebMD, a patient should call the dentist if severe pain or bleeding last for four or more hours after an extraction.
