My process was great in the beginning. The scan at the Smile Shop went well, and aligners arrived on time. However, results were not as they initially appeared on the treatment plan.
I needed certain tooth movements that would need attachments on the teeth to achieve, and being that the person I interacted with was not the actual doctor, it seems that my needs and concerns were never communicated through the chain. I wish that they would just say "We can't address that issue, this may not be the best treatment option for you," but instead they just collect the money and straighten your teeth as much as seems possible by their technology.
My final retainer was also completely miss-shaped upon arrival in that it did not fit over my gums. Customer service was clearly not familiar with my files or individual case, and I was frustrated to receive scripted responses instead of the information that I actually needed pertaining to my case. It felt more like an FAQ page than a conversation with a person.
In the end, SDC ended up being a major waste of time, money, and effort for me. I'm now going to have to pay double for Invisalign to actually address my issues with a real doctor and the proper technology.
Bottom Line: No, I would not recommend this to a friend
