Keep a food diary along with a list of all prescript
ion and over-the-counter medications, as well as vitamin or herbal supplements you take. This is especially helpful if your bad breath remains after stepping up your oral hygiene. Have a dental professional review these medications during your next oral exam. Some dental professionals specialize in bad breath, and the ADA maintains a list of each state's dental association as a resource for locating such specialists.
