Answer Question
What material makes it stronger than the “soft flexible” 3mm guard?
I have VERY strong/heavy grinding. I got 2 mouth guards from you guys about 2 years. One was acrylic, which I bit right through. Now the soft, more durable 3mm one is beginning to have holes in it. I don’t want to spend more money on a model that’s made with exactly the same material and just as thick. Any info is appreciated. Thank you!
