Brush everyday including scrapping tongue and still have bad breath what can it be

Bad breath: Bad breath is typically of dental origin, but you are addressing that problem. Another common source is food intolerances, such as lactose intolerance. You might try to eliminate dairy products and think of other foods which might cause indigestion. You can always consult with your dentist to make sure your teeth are in good condition and consider talking to your primary care doctor food intolerances.

Hygiene appointment: When was the last time you had a professional hygiene appointment with radiographs? Speak with the dentist to make sure that you don't have any underlying dental issues and make sure to floss regularly in addition to brushing at a 45% angle to get under the interface between the tooth and the gingiva. If no dental etiology is found, you may be referred to your MD.

Determine Cause: Brushing alone may not be the answer. Cavities, periodontal problems, acid reflux, diet, and sinus infections can all contribute to halitosis. Please call your dentist for an examination and take it from there.
