How long until this post-tongue ring scar will go away?

I took my tongue piercing out about a year ago and I still have this stupid indention scar thing. I want to get my scoop piercing, I always have wanted to but I want that scar gone if possible.

Just an FYI if it looks weird it's because I had crystal light earlier😅. But there is an indentation in my tongue where the piercing was. I also didn't want to get my teeth in the pic...
