Thanks beave, I’ve been using a tongue scraper and brushing my whole mouth and it’s still here. My dr has no idea. It could be from the antibiotics but i finished them weeks ago so I’m wondering if I need something else in case it’s a bacteria or fungus? I’ve obv scoured the Internet and it’s not the black hairy tongue that seems to come up in a lot of searches, it’s brown and flat patches. Regardless, once I figure out how to treat it I’ll update this just in case it ever happens to anyone here.
