I go to the orthodontist and for fifty cents they have a U shaped "Therapy Wafer" I keep in my mouth, especially at night. prevents me from clenching my teeth while I sleep. I can also use it during the day.

I buy a bag full of them.

for a little more $ a dentist can make a bite plate. I think $50.

for $500 my orthodontist made me a retainer. (well it came with the braces package deal). but he made mine slightly special, knowing I clench my teeth, he made it so my bottom teeth actually hit the top retainer first, just before my teeth would normally touch. this helps prevent me from developing TMJ, which one can develop from clenching teeth.

so I can wear my retainer all day if I want so I don't clench. well I still clench just my teeth don't touch so it doesn't develop pain.

those are my ideas. I like the 50 cent U shaped flat wafer as a cheap place to start. I sleep with it at night. (they say it's flavored but they really aren't, unless "plastic" is a flavor).
