Loose teeth with pre-finisher

[xjiaa]

Hi everyone,

I had my braces removed around 2 months ago and was given a pre-finisher appliance to adjust my overbite. I've been biting into it as instructed, however I've noticed that my bottom four front teeth have been loose and will move back and forth when I apply pressure onto it with my finger. I'm extremely concerned about this issue with the fear that this mobility will be permanent or teeth will fall out in the future. Can any provide me with any assurance?

Thank you,
