> A dentist will sell a custom fit version for several hundred dollars. (Both are useful for their need, the custom fit are more comfortable, but at a 10-20x price hardly worth it). I have one of these, my dentist wants me to wear it because apparently I grind my teeth, but turns out I can't wear it. A whole bunch of stuff goes wrong: The thickness means I have nowhere to put my tongue and between that and how it adds volume to my molars my jaw can't close all the way, saliva builds up in front of and below the guard (between the teeth/gums and lips) where I can't do anything to swallow it, and the plastic taste is terrible - the longest I've lasted is about 10 minutes before I have to run to the bathroom and take it out.
