I'm estatic with my Instasmile snap on veneers. They look so natural and at last I can smile for photographs without trying to disguise my horrible 'pirate smile' gappy teeth. It took me six attempts with the impression moulds to get a perfect impression of my natural teeth and gums and, although frustrating, it was worth the effort as the technicians at Instasmile are being maticulous about impressions for good reason; they want to make perfect looking and fitting veneers. So don't be put off if Instasmile reject the photos of the impressions that you submit; keep persevering and the results will be astounding! I can eat and drink with them fitted but soft foods only, not crunchy apples, nuts or chewy meat; and drinks shouldn't be too hot either. You can wear them daily but I choose to save them for special occasions so that they will last longer, as their normal lifespan is supposedly 3-5 years. My top and bottom set cost £300 so if I can get 5 years wear out of them that's £60 a year or just over £1 per week. An absolute bargain!
