I got my tongue pierced just under a week ago and there is a crater like indent developing on the top of my tongue. Why is this and what can I do to get rid of it?

This is because of the jewelry resting on the top of the piercing. I got one with my belly button and my tongue. But the one on my belly button is gone now, and the one on my tongue is almost gone. I got my tongue and belly button pierced about two months ago.
