I've sent in my impression of my teeth to get my Snap-on Smile custom fit. They sent me the box with the putty in it to make the impression. They also send one extra just in case. Well they have rejected both of mine that I have sent in for different reasons one was supposedly the putty was under mixed. Then my second one I sent they said I had drag marks for my teeth so that one would it work well now I'm all out of the potty and I'm guessing they want me to buy more? I just want my teeth to be pretty.. So sad more??
