There are multiple reasons for malodour, and the commonest one is the presence of deposits On The Teeth called as calculus which cannot be removed by tooth brushing and cause continous gum inflammation. They can be removed by a procedure called as scaling for better looking teeth and improve gum health. You should also clean your tongue with your toothbrush after every time you brush your teeth and do not use a tongue cleaner for this purpose. Maintain a good level of hydration and eat fibrous foods like salads. Using medicated mouthwashes containing chlorhexidine gluconate will also be of great help (brand names like clohex/hexidine/rexidine, etc). Regards.
