Hi. what should i do to stop bad breath ?

Determine the cause: Determine the cause. Once you know what is causing your halitosis, then you can address the problem. Is it dental issues (cavities or gum disease)? Is it your diet? Gastric reflux? Tonsil stones? Oral hygiene? As you can see, it is impossible to tell over the internet, without an exam or med history, what your problem might be. Please see a local dentist and physician to be examined and treated.

Dental evaluation: See a dentist and find the cause of your breath problem. It may be decay, gingivitis, tarter build up or other causes. Brush and floss twice a day.

Source of odors: 3 sources of mouth odor: Descending from the sinuses, post nasal dripping. Ascending, stomach gasses and acid reflux, or oral. Is there any periodontal issues (untreated pocketing) that could be beyond the reach of your oral care regiment? could also be from behind where you can reach with the tongue scraper. Get the other factors checked out. May want to use probiotics
