Tongue: Perhaps you need to clean your tongue....Tooth brushing the tongue is one method, but, using a tongue rake is a more efficient option. Once a day, after you get a head start with more than once a day for a few days in the beginning, will jump start you to better breath. Also keep up your flossing.

Simple solution: In the majority of cases, the cause of bad breath, or halitosis, is the product of bacteria in the mouth. The proper diagnosis is the key to a successful treatment. See your dentist for Halimeter test, diagnosis and bad breath treatment that depends on its cause. Good luck.
