Instasmile are a company that makes clip on veneers for teeth. I paid £474 for a full set of top and bottom veneers. I was sent only the impressions kits to start the manufacture of the end product. The materials from the impressions products injured my mouth that I have a swollen upper lip and blisters. Instasmile have declined my impressions over and over again. I have cancelled my order and asked for a refund to no avail User's recommendation: Avoid.
