Anyone ever use a night guard for teeth to keep them from grinding?

The dentist recommended I get a mouth guard to protect my teeth from grinding against one another while I sleep. I've noticed that I do grind them, when I am trying to relax and fall asleep. They say that my grinding is the cause of a "disk" in my jaw deteriorating.

If you have used a mouth guard, did it work? The dentist was gonna charge around $300 for a custom one but I saw one at Walmart that looked more comfortable. It looked as if it only covers the back teeth, which is what I need. I'm just too cheap to spend the money with knowing if it really helps. Can't return a mouth guard, after all.

I used one in the past and it helped me although it took a while to get used to it. I used to wake up and find I had taken it out in my sleep and would find it in random places.
I had an expensive official one and then a cheap over the counter ready made one and the expensive one definitely fit better and was more comfy. Just a crazy amount of money for something that seems simple.

@mangomonkey Yes I bet. I started to purchase while I was at walmart but I was like, no I'll probably spit that big thing out. I"m gonna see if I can find a pic of one I was considering. See what you think since you've used one from dentist and OTC

@iamnikki that doesn't look too comfy.
I'd go for one that goes over all your bottom teeth

@mangomonkey K. I have some cheap mouth guards I bought since it was suggested for this teeth whitening kit I bought a while back. Thank you
