LORIOUS Mouthguard Review: 6-Pack Teeth Grinding Guard Tested

Quick Verdict

If you're hunting for an affordable mouth guard for teeth grinding that doesn't feel like biting down on a slab of hard plastic, the LORIOUS 6-pack deserves a spot on your shortlist. After two weeks of real-night use — including one particularly gnarly stress-dream night — it held up better than I expected for a boil-and-bite product. It's not a dental-office custom guard, but for the price, it does the job. I'd give it a solid 4.2 out of 5 for mild-to-moderate bruxism and sports use.

What Is the LORIOUS Mouthguard?

The LORIOUS mouthguard is a 6-pack of boil-and-bite dental guards marketed primarily at bruxism sufferers — people who grind or clench their teeth at night. It also doubles as a sports mouthpiece and whitening tray, which adds a layer of versatility you don't always see at this price point. Each guard is made from BPA-free, phthalate-free medical-grade material and can be trimmed and re-molded as needed.

I first heard about these when a coworker mentioned she was using a generic mouth guard from Amazon for her teen's braces-related grinding. That led me down a rabbit hole of overnight jaw pain solutions, and the LORIOUS set kept appearing in threads as a budget-friendly entry point. So I grabbed a set, labeled one for "review testing" and the other five for "backup," and got to work.

Hands-On Review

Night one, I boiled the water, dropped the guard in, and followed the instructions. The package recommends 20-30 seconds in boiling water — I went with 25. After letting it cool for what I thought was the right amount of time (spoiler: it was about 3 seconds too long), I bit down. The fit was... okay. Not great. There was a gap along my left molar that I could feel when I ran my tongue over it.

Rather than suffer through a week with a subpar fit, I re-melted it on night three. This time I was more aggressive — pressed harder with my fingers, made sure the material fully wrapped around the back molars. The difference was immediate. By night four, I'd forgotten I was wearing it. That's the real test: does it disappear once you're asleep?

What surprised me was the material memory. After five consecutive nights, the guard still snapped back to my custom shape when I reheated it for cleaning. Some boil-and-bite guards get lazy after a few cycles — this one didn't. I also appreciate that the package includes six guards. If you grind heavily on one side (as many people do), you can swap guards to let them rest and extend their lifespan.

The plasticky smell I mentioned earlier? It's there on day one, straight out of the packaging. After the first two washes with cool water and mild soap, it faded significantly. By the end of week one, I couldn't detect it anymore. Your nose may vary, but it's worth knowing so you don't think something's wrong.

For sports use, I tested one guard during a weekend basketball scrimmage. It's not a proper athletic guard — the material is thinner than what you'd get in a boxing or football mouthguard — but for recreational play and practice, it works fine. Just don't expect it to absorb the kind of impact a football lineman deals with.

Who Should Buy It?

The LORIOUS mouthguard is a good fit if:

• You've recently started noticing jaw soreness or tooth sensitivity and want a budget-friendly first step before seeing a dentist
• You need multiple guards for a household — the 6-pack is genuinely good value
• You're looking for a dual-purpose guard that works for mild bruxism and occasional sports
• You want to try a custom-ish fit without committing $300-600 to a dentist-fitted occlusal guard

Skip this if: you've been diagnosed with moderate-to-severe TMJ disorder or your dentist has already recommended a custom hard acrylic guard. Boil-and-bite guards like the LORIOUS simply can't provide the precision fit or durability that heavy grinding and jaw dysfunction demand. For those cases, this is a temporary patch, not a solution.

Alternatives Worth Considering

If the LORIOUS doesn't feel right after your first couple molds, here are two alternatives worth knowing about:

SomnoGuard AP ( Bruxism Dental Guard) — This is a two-layer guard with a harder outer shell and softer inner cushion. It's a step up in construction quality and tends to hold its shape longer. Pricier at around $40-50, but the fit is more consistent out of the box.

Chomper Labs Custom Night Guard — For a true custom fit without a dentist visit, Chomper Labs sends you an at-home impression kit. You mail it back, and they build a guard specifically to your teeth. It's in the $80-120 range and is noticeably more comfortable for long-term bruxism management.

FAQ

Final Verdict

The LORIOUS mouth guard for teeth grinding is a competent, affordable option that punches above its weight for mild-to-moderate bruxism. The 6-pack value, BPA-free materials, and versatile fit options make it a smart first purchase if you're new to dental guards or want coverage for multiple users. The initial odor and learning curve on molding are minor inconveniences, not dealbreakers.

Will I keep using it? Honestly, yes — I've already rotated in guard number two and haven't woken up with that familiar jaw ache in over a week. For anyone on a budget or just starting to take bruxism seriously, this is a low-risk place to start.
