“Why do I have bad breath sometimes?”?

bad breath
bettyboop asked:

Periodically I get bad breath. I floss every other day, I brush my teeth twice a day, I brush my tongue and palette once a day…and still periodically I get bad breath. It is a tendency for my teeth to harbor foods easily and I am prone to cavities but I went to the dentist and she said everything is fine. What can it be? Also, I usually get bad breath right before my period.
Oh, and is bad breath hereditary?
