I just got my first guard from Clearclub and it fits great. Less than 1/10 the price (I think $90 for a year, get a new one every six months) and the same polymer tray molds that the dentist uses. Might be worth a shot.

I’ve had several night guards from dentists but chewed through them pretty quickly and it gets expensive.

I’ve been wondering about these sites, there’s several of them. I really need a new guard but I’ve seen some reporting that dentists might be a very high risk place to be. Did you have any problems with fitting / making the mold?

No it was a piece of cake. Exactly like the dentist’s assistant did it at the office, with likely the same putty. Tray looked the same too.

I’ll note in my case that if the guard isn’t precisely balanced I get a worse ache in my jaw, as I can often redirect all the tension towards a single tooth. You may be lucky in that a one size fits all guard is sufficient!

I have a dentist-fitted guard and it's much more comfortable. Highly recommended.

The cheapest guards made of only soft plastic, which will not slide easily across the lower teeth. Get one with base of hard plastic.

Expect to spend over an hour getting it fitted just right, minimizing stress concentration points.

My dentist warned against store-bought guards because they're not as adjusted to the wearer and could damage your jaw in the long-term.
