I am missing a few teeth and had a chipped tooth. After reading other reviews I decided to try Instasmile. I ordered top and bottom. They sent me the impressions and puddy right away. After first try, I didn't get the molding right. They called me and explained the right way to get it right. They were professional and understanding to my needs. I got it right the next time. I sent the impressions back and they made my teeth to perfection! I was astounded by how they made the teeth like my younger years teeth to the exact!!! You will not be sorry if you try them. My teeth are pretty and gave me my confidence back. THANK YOU INSTASMILE
