Anyone know what is a long lasting remedy for bad breath?

Depends: The cause of your breath odor is critical in determining the best remedy. It may be tongue brushing if you have a fungal infection, or you may need treatment for a periodontal infection or acid reflux. Usually tongue brushing and flossing alleviate most of the problems! thanks!
