haha there's a thread for teeth brace ya?

I'm also wearing teeth brace, for a year now... had 4 teeth extracted too, but i feel the upper 2 teeth shouldn't be extracted coz i feel there were enough space... Now there's still these 2 big gap up there... Are these gaps really will be filled up eventually? the doc got ask me to put on the elastic as well, but for months, i feel the gaps are still the same....

and during last appointment, the doc put something like a 'stopper' behind some of the teeth... now my teeth can't bite fully, really make eating difficult....

hey guys wanna ask, what are the good alternarives to invisalign? Invisalign is too expensive for me. I have heard about zenyum and clear smile but zenyum seems to be only for cosmetic adjustment.
Some of the clinics i have asked are doing XX smile which i am not sure whether is it same as clearsmile?
Any good recommendations?
