[|Human|] Hi, a month ago I had tonsillitis and was given antibiotics. I then got a funny taste and white tongue, Dr said suspected oral thrush but treatment did not work, even fluconazole. My tongue is still white will not brush off and is sore, I seem to be getting a lot of mouth ulcers (I do get these sometimes but this is more often) and inside my lips and cheeks sometimes looks red or almost stings. What could this be? Swab that Dr did for thrush I think came back negative
[|AI|]  Hello, Welcome to ChatDoctorIf the KOH smear for fungus was negative, and the lesions did not respond to Fluconazole, then it is not oral thrush. When you are on antibiotics, it also destroys the friendly bacteria which are involved in maintaining the health of the mouth. The fissure of the angles of the mouth is suggestive of Riboflavin (a B vitamin) deficiency. Please take B complex vitamins and a multivitamin for other subclinical deficiencies and your oral health ought to improve. Take Care Chat Doctor.
