Invisalign..has made parts of my gums disappear..

[stellawalnuts]

I'm on my 11th set of trays (top & bottom) and I've noticed that the gum area attached to the bottom two front teeth in my mouth have begun to disappear. It kinda looks like the teeth can easily be pulled out or something. I'm HOPING it's because it's part of the moving process...but I'm not quite sure and it's starting to freak me out. A friend of mine said the same thing happened to her (just not as bad as mine) & her gum area grew back. This puts me a bit at ease but I still want to know...Has this happened to anyone else? And I've attached a photo of my teeth, look at the bottom below my two front bottom teeth.

I started to notice kinda the same thing going on in my lower teeth, you are probably brushing too hard and right after eating foods containing sugar wich I've read causes your gum to dissapear slowly. I'd say it's normal IF you are fixing crooked teeth since they'd be moving forward to where used to be no gum at all? Might grow back after some time like it happened to your friend but ask your dentist/orthodontic about it and let us know what he said =P
