Invisalign and buttons?

Question

I just got the first tray (of 20!) and I have 11 buttons, 2 of which on my upper front teeth. is there a chance that they'll take off some of the buttons before the end of this 40 week treatment?

Answer 1

It depends if the teeth move into the right positions

Answer 2

not really, i only of 2 on each top and bottom

i have 4 attachments(buttons)

and i they dont take it off... unless it falls accidently so i had three and got another one again
