My 9 month old granddaughter has what looks like a brownish black smear on her tongue. She was diagnosed with mercer not long ago and has been using a neb for croup
Anyone have a clue? It is not sore will not come off.

My Thanks to ALL, Kathy

Are you guys washing her mouth out after she uses the nebulizer or puffers? (it could be a fungus)
Also has she beenon any anti biotics? Has her doctor seen the mark?
Have the parents or you tried to brush it off with a toothbrush?

Kathy, I understand your dilemma, but looking for a diagnosis over the internet can be a dangerous thing.

Your granddaughter should be seen by her pediatrician for a proper diagnosis and treatment.

What do you mean "she was diagnosed with mercer"? I've never heard of that. Do you mean MRSA? Has she taken antibiotics recently?
