Bad breathing is not only caused from food trapping on teeth gap or plaque, but also from bacteria on the tongue. Therefore, do not forget to brush your tongue along when you brush your teeth. Normal toothbrush or tongue scraper will do. Getting rid of the bacteria from the tongue will make your teeth cleaner and reduce the bad breathing problem. Lastly, do not forget to have an appointment with the dentist every 6 months to check your oral health.
