using various drugs might not help solve permanent solutions to mouth odour ....mouth odour can be caused by 4 to 5 major causes .....1 ....it might be caused by dental issues
2.....it might be caused by medical issues e.g ulcer and some other gastrointestinal issues 3....it might be psychological ...meaning you might still think you have it after seeing the dentist and the medicals base on it as been programmed to your brain ......... my message to everyone the first place to visit once you noticed mouth odor is a dental clinic ...from there other referal might comes in if its not dental issues .
