Hello sir and good morning. hallitosis is a problem that can sometimes be difficult to deal with. The causes can also be many and may not even be dental sometimes e.g from the nose, food pipe or a medical problem like pneumonia or diabetes. For the basic mouth one, try getting a tongue scraper and thus is believed to be the number one cause of bad breath. After brushing for at least two minutes, use a tongue scraper to scrape it then use mouth wash. .try carrots , try chewing gum since dry mouths too can cause bad breath, eat lots of fruits adter your meals, floss regularly.
If all these don't help consider seeing a doctor who may look for a systemic cause for the bad breath or an ent surgeon who will assess you.
