Mouth Guard for Grinding Teeth

Horrible product - very soft material, tastes bad especially when heated and initially forming in mouth. Accidentally over-heated first one, it shrank and didn't form right. Used thermometer for second, timed, it formed ok, but it's so soft even when cool that I could bite right through it. I'm afraid I'll either bite through it or it will come loose at night and choke me, so I won't use it. Lesson learned, get a better quality one!
