Yes, but you can only wear fixed ones. There is no harm, that is, it will hurt for 2.3 days every time you exert force, and most people can bear it. You can't eat hard things like almonds. Then, after all, wearing things on your teeth will affect your appearance. I just wore it for more than a week, and it didn't hurt at all on the fourth day. Now I can chew hard things with my big teeth. The white ceramics I made are not obvious, but my lips are still a little protruding, which is a bit embarrassing. I hope it helps you.
