Hi mam,
You can go to any clinic near by, and check your current status. Hopefully you need a new retainers that's all. Please don't use broken one it is useless.
For new retaines to be fabricated, you need new impression. Go for Hawley retainers so that small gaps can be closed, after which you can go for clear retainers.
