How to have fresh breath all day?

I brush my teeth with an electric brush for 2 minutes, use an OraBrush tongue cleaner/scraper on my tongue, floss, and use mouthwash. Yet, throughout the course of the day I find myself having to chew gum because my mouth starts to feel not-so-fresh. What is the cause of this bad breath to come within 3-4 hours and how to do I stop it from happening?
And I mean to say that I want the fresh breath without having to chew gum and mints all day.

Mouth spray. You didn’t say anything about not mentioning that..

Is Tongue Cleaner Effective for Bad Breath?

Why is it so?

it can be effective as it can keep your tongue free from bacteria. but it cannot totally keep the whole mouth clean. proper techniques of brushing and flossing can effectively get rid of bacterial plaque which causes bad breath and other dental problems. the use of an all natural oral rinse is a great way to wash away food particles left on teeth and gums, it also promotes oral hydration, keep bad bacteria at bay, keeps teeth and gums in good condition and promotes fresh breath and clean mouth.
