I have had a white tongue coating for months it seems as though everything i eat stains my tongue, been to PCP and ENT, had allergy test, brush biopsy, given antibotics, and tongue meds to no avail, i have had various sensations over the past 6 months with my tongue, nausea,
dry mouth at times, nasty taste in mouth, tingling on tip of tongue, burning sensation, also irrirated more by certain toothpaste, mouthwash, and spicy foods. Going to see dentist next week, hoping there is some relief.
