I have loose teeth after braces.

I took off my braces 2 weeks ago, after wearing them for 1y. My front teeth (inferior jaw) are loose, i can wiggle them with my fingers (if i grab them and move), and they feel very very loose. I got my retainers 5 days after i took the braces off (those teeth had already shifted quite a lot, i had to push hard on one of them to make it fit into the retainer - with a lot of pain-, but after a couple of days the problem sovled). I'm quite worried about the wiggling. I want one more opinion.
