Aly asked:
I brush my teeth, floss, and use mouthwash daily. I went to the dentist a week ago and she told me that my gums and teeth were healthy. I also brush the tongue whenever I brush. I thought I might have something wrong with my inner organs, so I went to the doctor, but he too, told me that they were healthy. I do smoke, but I only smoke 1-2 cigarettes a day or a few per week. I also chew sugarless gum and drink water. Why do I have occassional bad breath? Sometimes I do and other times, I don’t. Why?
