Thrush how to make it go away?

Thrush=fungus: Thrush is relatively common in infants/children, but not so in health adults unless something happened..Such as recent use of antibiotics, infections, steroid uses (such as those for asthma/copd/allergies), or immunosupressed states such as hiv, cancers etc...So, check with your doc. If it is thrush, it can be easily treated, but this requires a prescription from your doc... Good luck.

See your doctor: You don't say where you have it so depending on the region see your dentist or physician so they can prescribe the appropriate medication.

Thrush in an adult?: You should be seen by a doctor and tested for immune deficiency states, including hiv. Normal adults who are not diabetic or taking antibiotics should be having thrush without some underlying reason. Go get evaluated.
