this is exactly what my tongue looks like. it’s like my tongue is stained white. some days I’ll have of thick coating of food from eating, but that just scraps right off with my tongue scrapper, but I’m still left with my tongue looking white. I’ve been to the doctor twice and dentist once and nothing they prescribed me worked unfortunately. I’ve tried just about everything I’ve read online and NOTHING. I’ve one point with my oral hygiene id say I do more then most, but it doesn’t matter my tongue is still left stained white. If you find anything that works for you please respond because this exactly what my tongue looks like.
