Actually the lot of reasons for bad breath. So better to visit the dentist First they diagnose properly and tell you each n every step how to protect the teeth and gums from bad breath and most importantly the brushing time duration and techniques also you should go for scaling fr better results.

Best advise to you would be-please visit a dentist & let him /her check your oral cavity thoroughly.  Then only one can give you an advise /reason behind your problem.

Hi.... Brush your teeth after you eat... Brush using a fluoride-containing toothpaste at least twice a day, especially after meals. Toothpaste with antibacterial properties has been shown to reduce bad breath odors.... Floss at least once a day. Proper flossing removes food particles and plaque from between your teeth, helping to control bad breath..... Brush your tongue. Your tongue harbors bacteria, so carefully brushing it may help reduce odors....
