Im doing my braces with Dr Anitawaty at Subang Perdana. You should meet her before you decide.
My case is one of the pioneers, which doesnt involve extraction.
Today I just put on my power chains, cos I think the gaps made are enough already. (yup, made gaps without extraction)
So, its time to pull the teeth in. 

Actually, next Saturday I also have to participate in a mini showcase of how successful the new method is. 
She's gonna give a brief or something to fellow practitioners.

From what I understand, the literature (which is a lot of bull) said something about if youre more than 12 years old.
Any attempt on rearrangement of the teeth will result in nerve complications.
It's not really proven, but dentists everywhere have taken it as gospel so they just pull out your teeth.
