Several conditions: Several conditions in the mouth can cause halitosis (bad breath), such as gum disease, dental infections, poor dental hygiene, tonsil infections, multiple oral ulcers, etc... In children (or sometimes adults), if constipation is severe, the stool can be backed up so far that there are fecal odors coming out the mouth... so an exam is needed to see what is going on.
