What is the treatment of halitosis ?
- Maintain a good oral hygiene by brushing your teeth at least twice daily (especially after eating sugary food). Brush your tongue as this will brush away all food remains and bacteria. Use a dental floss every day to remove food remains between your teeth. The following video shows the correct way to brush your teeth:
- Drink water regularly or chew a sugarless chewing gum. This will stimulate production of saliva which will wash away remained food particles and bacteria.
- Avoid eating foods containing garlic and onions.
- If bad breath persists, schedule a dental checkup. A normal individual must do a dental checkup every 6 months.
