Bruxism - the clinical name for teeth grinding - affects an estimated 8-10% of adults and causes enamel erosion, jaw soreness, and headaches that compound over time. A well-fitted night guard creates a protective barrier between upper and lower teeth, absorbing the force that would otherwise chip enamel. These five guards range from lab-fabricated custom options to reliable OTC picks.

Dental Duty Professional Dental Guard
Dental Duty ships an impression kit, you mail back your molds, and a dental lab fabricates a guard designed to your exact bite. The dual-layer construction - soft cushioning interior with a harder exterior shell - handles moderate to heavy grinding without feeling rigid against the teeth. The turnaround is typically 2-3 weeks.
Pros: True lab-fabricated fit, dual-layer material handles most grinders, solid case included Cons: Longer wait for the finished guard, not ideal if you need relief immediately
Tranquil Guard Pro Night Guard
The Tranquil Guard Pro targets moderate grinders who want a soft, comfortable fit without the steeper price of hard acrylic. Medical-grade EVA material absorbs impact without feeling bulky. The impression process is straightforward, and most users report it fits snugly enough to stay in place through the night without causing morning jaw stiffness.
Pros: Comfortable soft feel, good for light-to-moderate grinding, easy impression process Cons: Soft guards wear faster than hard acrylic with heavy grinding
Pro Teeth Guard Custom
Pro Teeth Guard offers three hardness tiers - soft, hybrid, and ultra-hard - making it one of the few mail-in services that caters specifically to severe grinders. The ultra-hard acrylic option mimics what a dentist would prescribe at a fraction of the in-office cost. Each guard comes with a protective case and a satisfaction guarantee.
Pros: Hard acrylic option available for heavy grinders, tiered options, guarantee included Cons: Hard guards require an adjustment period, thicker profile than soft alternatives
SleepRight Dura-Comfort Night Guard
The SleepRight Dura-Comfort skips the impression process entirely - its self-adapting wing system adjusts to fit without boiling or molds. It’s a genuinely useful option for people who want protection tonight rather than in three weeks. The design holds the jaw in a slightly open position, which some users find reduces clenching intensity.
Pros: Immediate use, no impression required, adjustable fit wings Cons: Not as precisely fitted as lab-made options, some users find the wing design bulky
DenTek Comfort-Fit Dental Guard
DenTek is the most accessible entry point on this list - a boil-and-bite guard available at most pharmacies and easily found online. It won’t match the fit of a lab-made guard, but for light grinders or first-time users who want to test whether a night guard helps before investing more, it’s a perfectly reasonable starting point.
Pros: Very affordable, widely available, quick fit with boil-and-bite method Cons: Looser fit than custom options, may not stay in place for heavy grinders
What to Look For
Grinding severity determines which material you need - soft EVA for light grinding, hard acrylic for severe bruxism. Custom vs. OTC matters more than brand: a lab-fabricated guard retains and distributes force far better than a boil-and-bite. Check whether the guard covers upper or lower teeth - most cover upper teeth, but lower coverage is available and preferred by some wearers. Always verify the return/remake policy before ordering a custom impression guard.
Final Thoughts
If you wake up with jaw pain or have been told you grind at night, a night guard is one of the most cost-effective dental investments you can make - the enamel it protects cannot be replaced. Start with DenTek to confirm a guard helps, then step up to a lab-made option like Pro Teeth Guard or Dental Duty once you know the right hardness tier for your needs. And always run your choice by your dentist, especially if you have existing dental work.
Frequently asked questions
How is a mail-in custom night guard different from a boil-and-bite guard?+
Mail-in custom guards use dental-impression putty to capture an exact mold of your teeth, which a lab then uses to fabricate a precisely fitted guard. Boil-and-bite guards are softened in hot water and pressed manually, producing a looser fit. Custom lab-made guards typically offer better retention, more even bite force distribution, and greater comfort for long-term nightly use.
How long does a custom night guard last?+
A well-made custom night guard typically lasts 1-3 years depending on grinding severity. Heavy grinders may wear through a soft guard in 6-12 months; hard acrylic guards last longer but take more adjustment time. Rinse after each use and store in the provided case to maximize lifespan and prevent bacterial growth.
Can I use a night guard if I have dental work like crowns or veneers?+
You should consult your dentist before using any night guard if you have crowns, veneers, bridges, or implants. Some guards can put uneven pressure on restorations. A properly fitted custom guard is generally safer than a boil-and-bite option in these cases, but professional guidance is essential to avoid damaging existing dental work.
