J.K.
I had that when I was little. I got a retainer with a hole in the top and a wire guard that came down. I was suppose to keep my tongue behind the wire guard and in the hole when I swallowed. I also had a lisp when I said my S's so I went to speech therapy. I had to train my tongue to not thrust when I swallowed and when I said my S's before they'd put braces on me. I also had to stop sucking my thumb. I was a mess and so were my teeth. But the retainer helped and so did the braces. Good luck!!
