The hard plastic bent after two weeks of use.
It worked quite well for about two weeks. I had to mold it a couple of times to get the fit right and I had to cut it down a little, but it felt wonderful. A couple of nights ago, I noticed that the bottom hard piece was bent. It no longer fits like it used to. This night guard worked wonderfully, but if it doesn't last longer, it isn't worth the price if I have to buy another every two weeks.
