I ordered the a-2 shade for upper teeth. I was a bit hesitant and made sure not to get my hopes up but I was pleasantly surprised at how good these turned out. It was tedious matching up the right size and fit with each tooth I needed and some filing and shaping was necessary but no more than choosing the right nail tip when doing acrylics or something (just to use a comparison). I’m happy overall. Would recommend.These are great if you are covering a while tooth, but if you're covering a broken or less than half tooth, they are see through and it will look like you have a gray tooth.I went though a moment of temporary insanity and desperation. I have strained teeth and was looking for a quick cheap fix…. THIS IS NOT IT. Do not buy it. That is all.Reviews said not to buy but I was desperate. First I had made a tooth out of one of my children’s baby teeth we had saved and I put tissue around it and added super glue. Put that under water as water instantly cured super glue. Then took my partial new tooth and fobbed it with more super glue, took a deep breath and held it, then put it on my broken tooth to make a mold that I could let dry the. Glue to my broken tooth. Once I had glue gob pressed onto tooth I quickly flushed water into my mouth, curing the super glue, exhaled and spit out water and inhaled again. You have to make sure you don’t inhale super glue fumes into lungs. Dried my roughncrrstion and then put a small dot of glue on the impression dent of my new creation and glued it in place. Then I put tissue and super glue in back of tooth to make it the proper size. Took tooth back out after flushing with water to cure and then glued these veneers onto my new creation and the adjacent tooth toward my molars. I didn’t do a perfect job but it looks a million times better and I’m very happy. Then I filed the new creation to perfection. It’s a little crooked and really needs to be redone but I will just wait for it to get loose within a month or so and then maybe try for absolute perfection. You can’t eat with the beads. This method is just like having a real tooth. I can eat corn and drink anything I want. Super glue is okay once dry so you have to cure it quickly in mouth with water as soon as you have it pushed into place.
