Company was exceedingly helpful every step of the way. All questions answered rapidly. The process was not nearly as difficult as I thought it would be and anyhow I got it right the first time because I never had to use the extra mold tray. The veneer set itself is outstanding. For the first time in 20+ years I can grin big with my mouth open without worrying about who's looking at the gaps in my teeth. They look natural, and matched my natural color (I only got veneers for the top) quite well. In fact, after I sent them pictures they told me i'd selected a shade for the veneer too dark and it would not match. They were right. I couldn't be happier with how they look. I got the more expensive ones that they say you can eat with. You can, sort of. But they're not as sharp as natural teeth and they do move a bit when I bite down hard--which can be occasionally painful--so I'd still say it's best to remove them for eating. But they do appear to be extremely tough. The fit is extremely snug and there's no worries about them slipping off when I don't want them to. It isn't going to happen. The first few days of getting used to them can be a little rough, as they do hurt a bit from time to time until your mouth adapts to them. After the third day of wearing them I ceased even noticing them. Like I said, I'm very happy with the product and if these break or something you can believe I'll run, not walk, to Instasmile and get another set.
