get a full mouth scaling done from a dentist. start using antibacterial mouthwash (example: listerine) twice daily for two weeks. this is the best for stinking mouth (bad breath/ halitosis). another method for cure of bad breath is saline mouth rinse. take a small cup of lukewarm water and add 1/4th teaspoon of salt in it and rinse thrice daily for 10 days. you must get the cause identified. treating the root cause will give a permanent solution for bad breath. if the halitosis remains evenafter the use of mouthwash for two weeks consult a dentist online for further treatment.
