Bad breadth. Eat anything. please!

Hello, I understand your concern. There can be multiple reasons for bad breath. Some of them are plaque causing pyorrhoea, unclean tongue, GERD ( gastroesophageal reflux disease) diet related for example having milk before bedtime after brushing etc. So the correct reason needs to be diagnosed in order to solve the issue. As per your detail provided you were a tobacco user so it is advised to first get a cleaning procedure done (scaling) on order to remove plaque and stains from you teeth. Also incorporate the use of a non alcoholic mouthwash along with your brushing regime. And most importantly make a habit of cleaning your tongue with a non abrasive tongue cleaner or tooth brush. Follow the above for a week and check.
