Brief Answer:
Halitosis

Detailed Answer:
Hi,

Thanks for the query.

Bad breath or Halitosis is usually caused due to dental problems or ill oral health.
As you have visited a dentist and ruled out ill dental health, I would advise you visit an ENT specialist for examination and treatment.

Follow these instructions which will help in reducing bad breath:
1. Consume plenty of water (min 2 - 3lts/day). Drink a glass of water an hour before and after every meal. This will make sure consumption of adequate water.
2. Brush and floss your teeth twice a day. I believe this would have been advised by the dentist.
3. Clean your tongue with tongue cleaner every day.
4. Betadine oral wash - 5ml in 50 ml of water, gargle twice a day.
5. If any chronic oral infections like tonsillitis or pharyngitis. Please get it treated from an ENT specialist with antibiotics.
6. Gargle with water after every meal to avoid any food particles left in the mouth.
7. You can have mouth fresheners after every meal.

Hope this answers your query. If any further questions, will be happy to help.

Regards.
