What causes bad breath?
Poor oral hygiene
Too much curry the night before!
Bad breath is usually caused by bacteria in the mouth and is not usually a sign of ill health. If your mouth becomes dry, this can increase the risk of bad breath.
Get yourself a good oral hygiene routine .........
Brush twice a day with a fluoride toothpaste
Floss once a day and check for any areas that you notice bleed. Bleeding means more brushing of your gums as well as your teeth and more flossing.
Don't forget to clean your tongue, you can get tongue scrapers or just your tooth brush is good enough.
If you are still concerned then you should speak to your dentist.
