What's up with my tongue?

First of all lets discuss what a weird word “tongue” is when you think about it. Also, this was my random wikipedia article one time when I started Safari and I haven’t been able to stop thinking about how grotesque it sounds.

Okay back to business. I have had weird tongue “issues” since I can remember. First….my tongue is rarely red/pink like everyone else’s, but more whitish. Like this…..And it also gets those holes in it when I eat a lot of acidic food or sour candy. Currently I have two large holes on the surface of my tongue where the pink is showing through like in that picture. The whitish-ness has never been painful….just recently I took a flosser and tried to scrape the white off. Some of it did come off and it was really gross. But when I scraped too hard, it didn’t hurt, but a little bit of it did bleed a tiny amount. So, wtf is that???? I should also add that I’ve had multiple doctors appointments and dentists throughout my life who have seen my tongue like this and don’t even comment on it, so I’m pretty sure it’s nothing serious. I do brush my tongue. It does not seem to do anything. I have great oral hygiene. And some days it’s not white at all. But others, it’s very white! What is going on! And yes, I drink a lot of water. Does anyone else on here have this or know what it is?
