First of all, they will tell you that you are a candidate to lure you in. I do not have as hard case as some of the people, but because of the premolar, my front teeth will never be straight.
"Teeth are constantly wanting to shift, so yes, when you have the aligners out, your teeth will move back to where they previously were because they have not settled. " - per there email.
I will have to wear retainer till the rest of my life at night. SO till the rest of my life I will pay 99.00 dollars to renew that retainer. Not bad?! Right!
"Once you are done with treatment, you will be able to order retainers. The retainers will settle your teeth so they will not move. You will only wear the retainers at night, however, you will have to wear them for the rest of your life if you do not want your teeth to shift back. This is vital in any treatment that moves teeth, including the traditional orthodon'tic appliances. " NO ONE told me this before the treatment! Which I believe, is a scam!
They work only with your front teeth: from K9 to K9. They call it "desired U shape" which will cost me 99.00 every time when I will decide to renew my retainer. And again, no one told me about it.
It is a trap. DO NOT GO WITH THIS METHOD. It does not help, you will be stuck with it, and and the end you will pay even more than those regular braces. It will NOT give you a desired result, because the smile it is NOT only about the look, it is also about your health.
