                        Hi,  Have you tried brushing her tongue, much like brushing teeth?  Any pharmacy has toungue scrapers/brushes.  Talk to the pharmacist.  Second, Have you tried gargling with Hydrogen Peroxide?  Get the kind that says may be used as a gargle.  Third, Take Vitamin C, Ester C, (Ester C is ph neutral and will not hurt the stomach & stays in the blood stream longer than other Cs), with bioflavonoids.  Walmart carries them.
