In healthy people, the major reason is due to microbial deposits on the tongue, especially the back of the tongue. Some studies have shown that simply brushing the tongue reduced bad breath by as much as 70 percent.

Brush at least twice a day with an ADA approved fluoride toothpaste and toothbrush. Floss daily to remove food debris and plaque from in between the teeth and under the gumline. Brush or use a tongue scraper to clean the tongue and reach the back areas. Replace your toothbrush every 2 to 3 months.
Brush and floss your teeth at least twice a day, especially before going to bed at night.
