I want to get clear braces, so I’ve booked consultations at both Gangnam Central and ID. I noticed that the prices for Invisalign seem to vary quite a bit depending on the clinic. Some places offer them at really low prices, so does that mean not all Invisalign is the same? I’m worried that if I go without doing proper research, I might end up wearing ineffective braces. I’m curious how everyone else was able to distinguish between them and get treatment.
