-- do not breathe through your mouth.
-- eat fruits, vegetables, and whole grains. Chew parsley.
-- control your stress because stress makes your breath worse.
-- have a dental cleaning done at the dentist's office at least twice a year.
-- avoid onions, garlic, alcohol, coffee, spicy foods, candies, tobacco, and smoking.
-- do not use mouthwash containing alcohol or toothpaste containing sodium lauryl sulfate.
-- avoid breath mints, breath sprays, and chewing gums that contain sugar. Use sugarless gums that contain xylitol.
-- clean your teeth, tongue, and mouth. Brush, floss, and tongue scrape twice a day in order to prevent bacteria build up.

-- over-the-counter and prescription medications such as anti-depressants, high blood pressure medications, and anti-histamines can make your mouth dry.
