Check teeth again: Do you still have your wisdom teeth? If so they tend to build up plaque which causes mouth odor. Do you floss every day? Rarely halitosis (bad breath) can come from diseased tonsils. Are they large or painful? Do you have symptoms of sinusitis (headache, fever, cough, nasal congestion)? Sinusitis can cause bad breath in some cases. Try flossing more and have wisdom teeth removed.
