i had braces for 2 yrs. i got them off about 4years ago. and i havent really worn my top one in the past 2-3 years. (yes i know bad) well i am starting to feel them move. and my top retainer doesnt fit anymore.
i know that you can get the plastic/metal retainers (the ones i had), clear retainers (they look like invisalign but they are retainers), and permanent retainers.

i want a clear retainer for my top teeth now. (the reason why i never wore my plastic/metal top retainer was b/c i never got used to how far the plastic went back... ugh i cant stand it)
how much would it cost approximately???

also can i get some info on permanent retainers? even though i wear my bottom retainer every night my teeth still move some during the day. so i was thinking of getting a permanent retainer.

thanks
if you dont know what i am talking about....

(i just found this on the web)

a traditional metal retainer is called a Hawley Retainer.
a clear retainer is called an Essix Retainer.
and a permanent retainer is called a bonded retainer.
