I looked for a guard that seemed designed to absorb pressure and create a barrier between my teeth. That sense of protection gave me more confidence in using it every night.
Cleaning and Maintenance
I also considered how easy it would be to keep the guard clean. Since it goes in my mouth every night, hygiene matters a lot to me. I preferred something I could rinse and store without a complicated routine. A product that is simple to maintain is much more likely to stay part of my nightly habits.
