These teeth work great! At first today it took me about five tries to get the thermal beads right, but at the end I got it, and now they are better yet. It does take some time to get all the plastic adjusted right to where you do not have speech problems but if you order you will like these teeth. I ordered extra beads and actually glued the beads to the back of the teeth to make it more permanent. Thanks for a great low cost temporary smile until I can get my dental work done.
