Google says it’s left over acidity from the apple that goes from your teeth to your tongue. Health tap says reflux so the answer is probably acidity. Also this was an easy google search, not an elif question.

This is a sub to get answers to questions last I checked. Not a sub to tell people to google it.

The implication of subs like this is you've researched an issue before asking for clarification. Yes google is the first step in that.

The first step is google, second or third is ask reddit, the question has already been asked here too.

Welcome to your ELI5 guide, on your right, you can see the basic rule of this subreddit, and if you look closely, you might see that the number 1 rule is "be nice", and number 8 as "don't guess"

While the poster likely violated rule 7, that is for the mods to judge and not us.

I wouldn’t say I guessed, I looked up on google and gave a source, both things I referenced talked about acid, either from the apple or reflux. And it’s not like my comment was rude, blunt maybe, but not rude

Okay let me clarify a few things, I had looked at the rules before posting this and I did see and read rule 7. I then went to the search bar and searched for a post similar to this that would answer my question and didn't find any so I made this post. If I had seen a post that would've answered my question, I wouldn't of made this post. I might delete this post in the morning idk, I'll decide then. Sorry for violating rule 7, let's just all be nice to each other please.
