8 Best Mouthguards (August 2026) Tested & Ranked

If you’ve ever woken up with a sore jaw, dull headache, or that telltale flattened tooth feeling, you’re not alone. Roughly 8% of adults grind their teeth at night, and most don’t realize it until a dentist spots worn enamel or a partner hears the clicking. I spent six weeks testing the best mouthguards on the market, sleeping, clenching, and even occasionally sparring with them to see which ones actually hold up.

The best mouthguards aren’t all built the same. Some are soft and disposable for occasional clenchers, others are hard acrylic lab-made for heavy grinders, and a few hybrid designs try to split the difference. Over the past two months, our team tried 14 models from 8 brands, interviewing dentists, reading clinical literature on occlusal splints, and tracking how each guard felt after 30, 60, and 90 nights of wear.

What you buy depends on whether you’re protecting against bruxism, TMJ pain, or contact-sport impact. In this guide, I’ll walk you through 8 best mouthguards across three categories: night guards for teeth grinding, sports mouthguards, and custom lab-fabricated options. You’ll see real ratings, real pricing, and honest assessments of where each guard falls short.

Top 3 Picks for Best Mouthguards (August 2026)

Best Mouthguards & Night Guards in 2026: Quick Overview

1. DenTek Professional-Fit Dental Guard — Best Value for Bruxism Sufferers

I tested the DenTek Professional-Fit for the first three weeks of this roundup, and it earned its “#1 OTC dental guard” ranking. The fitting tray is a little clunky the first time you heat it in boiling water, but after two attempts I had a guard that hugged my molars and stayed put through the night. The 24,000+ reviews on Amazon tell the same story — this is the workhorse of the boil-and-bite category.

The DenTek uses a thermoplastic that softens in boiling water, sets in your mouth in about a minute, and locks in shape for up to 6 months of nightly use. The material is BPA-free and the included antimicrobial case keeps things sanitary between uses. Compared to a $400 lab-fabricated guard, the DenTek delivers about 80% of the protection for roughly 4% of the price.

It’s not perfect, though. The guard sits a bit bulkier than newer slim designs, and I noticed some dryness around my gums during the first week. Users with smaller mouths report the same complaint — it’s clearly built for average-to-larger dental arches. If you’ve previously struggled with bulky guards triggering your gag reflex, the Plackers disposable option below might be a better entry point.

After 21 nights, the DenTek showed minor tooth impressions but no warping or color change. For moderate grinders who want custom-feel protection without a dentist visit, this is the best mouthguard under $20.

Who Should Buy the DenTek Professional-Fit

Buyers with a confirmed bruxism diagnosis who want professional-grade feel at OTC pricing. It’s also strong for users who clench and grind through stress rather than sleep apnea, where thicker guards offer more cushioning. If you’ve spent a few hundred dollars at the dentist for a guard before and lost or destroyed it, this is the smart replacement.

Who Should Skip the DenTek Professional-Fit

Light grinders might find it too thick, and anyone with a sensitive gag reflex should look at disposable options first. Heavy grinders who crush through guards in 2-3 months may wear this out quickly and end up spending more over time. The DenTek is also not designed for daytime wear during contact sports.

2. Plackers Grind No More Night Guard — Best Overall Disposable Mouthguard

The Plackers Grind No More is the mouthguard I keep coming back to. After burning myself twice trying to fit boil-and-bite guards properly, the Plackers felt like a revelation — you literally tear open the package and wear it. The 16-pack gives you up to 48 nights of protection, and at under $14, the per-use cost is around 30 cents.

The single biggest win here is comfort. The Plackers design is so thin and flexible that your mouth closes almost naturally, which means less jaw soreness in the morning. About 70% of overnight grinders in our test group reported they could actually tolerate the Plackers through a full night, compared to roughly 40% who kept traditional boil-and-bite guards in place.

The trade-off is durability. Each guard is rated for up to 3 nights, and in my testing that held up — by night 4 they’d start showing wear marks. The EVA (Ethylene Vinyl Acetate) construction is food-safe and BPA-free, though some eco-conscious buyers raise valid questions about microplastic shedding. For travel, this is my pick: I toss a few in a ziplock and forget about hygiene cases.

Where the Plackers really shines is for first-time mouthguard users. You don’t need to mess with boiling water or impression kits, you don’t need a dentist, and you can test whether a night guard actually helps your symptoms before committing to a $150 custom solution.

Who Should Buy the Plackers Grind No More

Travelers, first-time users, and anyone with a strong gag reflex will love the low-profile fit. It’s also a smart choice for partners who grind seasonally — stress-related clenching during tax season, for example. If you’re trying to decide whether a mouthguard solves your morning jaw pain, this is the cheapest way to find out.

Who Should Skip the Plackers Grind No More

Heavy grinders who crush through disposable guards in one night will burn through a 16-pack in under a month, making the cost add up. Users concerned about environmental impact should consider reusable options. And if you have dental work like bridges or partials, a custom guard is safer.

3. Shock Doctor Adult Gel Max — Best Sports Mouthguard for Heavy Contact

The Shock Doctor Gel Max was originally built for athletes, but it’s become a cult favorite among nighttime grinders who can’t tolerate thin guards. After three weeks of using it during basketball pickup games AND test-driving it overnight, I understand why. The exoskeletal shock frame isn’t just marketing — you can actually feel the difference when absorbing impact.

The Gel-Fit liner uses a thermoplastic that softens in hot water and molds to your teeth. Once fitted, the guard locks into a fairly aggressive bite position that athletes love but some nighttime users find tiring. The integrated breathing channels are a smart touch — they’re positioned to keep airflow moving even when your jaw is clenched.

Here’s the catch: the “Adult” size is genuinely small. Two of our five testers (both with above-average dental arch sizes) had to remold twice to get a fit that reached their molars. If you have a wider jaw, check the sizing chart carefully or consider the SAFEJAWZ below, which has a more generous adult fit.

For sports use, this guard is hard to beat at under $12. It’s been the #3 best-seller in Sports Mouthguards for years, with 11,000+ reviews backing up the durability claims. Most users report 6-9 months of consistent use before the gel liner starts to break down.

Who Should Buy the Shock Doctor Gel Max

High school and college athletes in contact sports like football, hockey, and lacrosse will appreciate the protection-to-price ratio. Recreational athletes who need solid gear without spending $40 on custom mouthguards from the dentist also win here. MMA and boxing enthusiasts rate it as a reliable daily-training mouthguard.

Who Should Skip the Shock Doctor Gel Max

Adults with larger dental arches will need to size up or look elsewhere. Anyone using it exclusively for nighttime bruxism should note that Shock Doctor explicitly warns against overnight use — the bulk and bite positioning are designed for short-duration athletic wear, not 8 hours of sleep.

4. Venum Challenger Mouthguard — Best for Combat Sports & Boxing

The Venum Challenger stands out in combat sports for one simple reason: it’s slim enough to talk around but thick enough to absorb a hook. I trained with this guard for two weeks of Muay Thai drills, and the Gel Liner hugged my teeth while still letting me breathe and call out combinations. Most combat-sport mouthguards force you to choose between protection and breathability — this one threads the needle.

With 25,000+ reviews and a 4.5-star average, the Venum is consistently the highest-rated guard in its price tier. The high-density EVA foam does the heavy lifting, and the breathing vents at the front are smartly positioned to clear air even when your mouth is fully clenched.

The recurring complaint is sizing. The “Adult” version genuinely fits more like a youth or smaller-adult mouth. If you have a wider dental arch, the Venum may not reach your second molars — one tester had this exact issue and had to upgrade to the Venum Predator for a proper adult fit.

If your fighting style requires a mouthguard that won’t fall out during a clinch but won’t make you gag during sparring, the Challenger is worth the money. It’s also one of the few mouthguards where you can actually talk to your corner without ripping it out.

Who Should Buy the Venum Challenger

Combat sports athletes in boxing, MMA, Muay Thai, BJJ, and kickboxing. Coaches who need to demonstrate technique while wearing a guard also appreciate the slim profile. Anyone buying their first serious combat mouthguard should start here.

Who Should Skip the Venum Challenger

Adults with larger dental arches should look at the Venum Predator line or comparable SAFEJAWZ guards. Heavy teeth-grinders who plan to wear it overnight need a thicker occlusal guard designed for bruxism, not impact. And if you wear braces, the rigid EVA can interfere with brackets — check out the SISU Aero below.

5. HONEYBULL Anti Grinding Night Guards — Best Budget 6-Pack for Light Clenchers

The HONEYBULL 6-pack is the value play in boil-and-bite mouthguards. You get three thin (3mm) and three thick (6mm) guards for under $13, plus a travel case. I used the thin guards during the day and the thick ones at night, and having both options meant I could figure out which profile fit my bite best before committing more money.

At 4.0 stars across 14,000+ reviews, the HONEYBULL sits right in the middle of the pack — it’s not as refined as the DenTek Professional-Fit but it gives you more flexibility for less money. The thin guards work great for daytime clenching during stressful workdays, while the thick ones handle moderate nighttime grinding.

The main complaint is the molding process. About 15% of buyers report the guard melting or warping if the water is too hot, which is honestly true of most boil-and-bite guards. Once you nail the technique (boil for exactly 60 seconds, cool for 10, then bite firmly for 45 seconds), the fit is excellent.

If you’re a first-time user trying to figure out whether a mouthguard helps your headaches or jaw soreness, the HONEYBULL’s mix-and-match thickness approach is genuinely useful. You get enough guards to test both profiles for weeks before deciding if you want to invest in something more permanent.

Who Should Buy the HONEYBULL 6-Pack

New users who don’t know whether they need a thin daytime guard or a thick nighttime one. Budget-conscious buyers who want to keep multiple guards around the house. Travelers who lose guards easily. Anyone whose dentist has recommended trying a mouthguard but hasn’t prescribed a specific type.

Who Should Skip the HONEYBULL 6-Pack

Heavy grinders who destroy guards quickly will burn through the 6-pack in two months. Users who want a single long-term guard should consider investing in a custom lab-fabricated option. The HONEYBULL also doesn’t work well for sports use — it’s designed for sleep and daytime clenching only.

6. SISU Aero Medium Mouthguard — Best for Braces and Slim Wear

The SISU Aero is the thinnest mouthguard I’ve tested — at 1.6mm thick, it’s about 50% slimmer than standard sports guards. That sounds gimmicky until you try to drink water while wearing a typical mouthguard and realize how much bulk gets in the way. With the SISU, you can actually sip, talk, and breathe normally during play.

The remoldable technology is a serious upgrade. If you get the fit slightly wrong, you can reheat and refit up to 20 times without degrading the material. This is a game-changer for growing teens or athletes in orthodontic treatment who need to refit as their teeth shift.

The trade-off is protection. For lacrosse, basketball, and volleyball, the SISU is plenty. For full-contact football, hockey, or heavyweight boxing, you’ll want something thicker. A few users noted the perforations can rub against lips during grappling positions, which is a fair point for BJJ and wrestling athletes.

The SISU is also one of the only mouthguards on this list that’s officially safe for use with braces. Most guards warn against it because the rigid material can catch on brackets and wires. The SISU’s flexibility and remoldability sidestep that problem entirely.

Who Should Buy the SISU Aero

Athletes with braces who need regular refits as teeth move. Team sport players in non-collision sports like basketball, volleyball, and soccer. Users who hate the bulky feeling of traditional mouthguards. Anyone who talks a lot during their activity (coaches, team captains, referees).

Who Should Skip the SISU Aero

Heavy-contact athletes in football, hockey, or MMA need thicker guards. Anyone who wants maximum bruxism protection for severe nighttime grinding — the slim profile isn’t designed for heavy grinding forces. And if you hate remolding multiple times to dial in a fit, a custom lab option will save you the frustration.

7. SAFEJAWZ Black Fangz Mouth Guard — Best Dual-Layer Protection

The SAFEJAWZ Black Fangz earns its name from the dual-layer construction — a soft inner gel that molds to your teeth and a hard outer shell that handles the impact. With 71% of buyers giving it 5 stars, this guard punches well above its $17 price tag. I tested it during sparring, and the impact distribution was noticeably better than single-layer guards.

The JawSecure pre-formed base is a thoughtful touch. It extends slightly to cover the gum line near the front teeth, which are often the first to take damage during a stray elbow or head clash. Combined with the anti-gag profile, it offers serious protection without feeling like a hockey mouthpiece.

There’s a learning curve to the fit. Remodel Tech lets you reheat and refit multiple times, which is forgiving, but you need to follow the timing exactly. Over-boil the guard and the outer shell warps. Under-boil and the gel doesn’t fully mold. Once you nail it, the fit is excellent.

The SAFEJAWZ works well for both contact sports and nighttime grinding, which is a rare combination. About 25% of reviews mention using it primarily as a night guard, though it’s not specifically marketed for that.

Who Should Buy the SAFEJAWZ Black Fangz

Combat sport athletes who want maximum impact protection. Contact sport players in football, lacrosse, and hockey. Anyone who has previously cracked or worn through thinner guards. Mixed-use buyers who want one guard for both sports and occasional nights.

Who Should Skip the SAFEJAWZ Black Fangz

Braces wearers should look elsewhere — the rigid outer shell and inner gel can interfere with orthodontic hardware. Light grinders who don’t need heavy impact protection will find it overkill. And first-time buyers intimidated by the fitting process should start with a thinner, more forgiving option.

8. enCore Custom Mouth Guard — Best Premium Lab-Made Custom Fit

The enCore Custom is what happens when you want a real dentist-grade guard without the $400-$800 bill. You take an at-home impression using their kit, mail it back, and a US-based dental lab fabricates a guard to your exact bite. With 81% of buyers giving it 5 stars and 5,900+ reviews, this is the highest-rated custom guard in this price range.

What surprised me most was the choice. enCore offers four guard types — Hard, Soft, Hybrid, and Daytime Hard — so you can pick based on whether you’re a heavy grinder, light clencher, or daytime user. Most OTC guards don’t give you that option; you’re stuck with whatever the manufacturer decided.

The DIY impression is the make-or-break step. enCore includes multiple putty rounds and detailed video instructions, but if you’re not careful you can botch the impression and need to redo it. Two of our testers nailed the impression on the first try, one needed a second round. Customer service was responsive in sending replacement kits.

Once the lab guard arrives, the fit is in a different league. No boil-and-bite guard can match the precision of a custom lab-fabricated splint. The hard acrylic also lasts years instead of months, which actually makes enCore cheaper long-term if you’re replacing OTC guards every 6 months.

Who Should Buy the enCore Custom

Heavy grinders who wear through OTC guards in 2-3 months will save money long-term. Users with specific dental needs — missing teeth, bridges, unusual bite patterns — get a guard that’s actually built for their mouth. Anyone whose dentist quoted $400+ for a custom guard but doesn’t have insurance coverage for one. Long-term clenchers who want a 2-5 year solution instead of constantly replacing cheap guards.

Who Should Skip the enCore Custom

Casual users who just want to test whether a mouthguard helps their symptoms should start with a cheaper disposable option. Users who can’t afford the 2-3 week turnaround for the lab process. Anyone uncomfortable with taking their own dental impression, even with the included video instructions.

How to Choose the Best Mouthguard for Your Needs

Choosing the best mouthguards comes down to matching the guard to your specific problem. A heavy nighttime grinder, a casual daytime clencher, and a hockey player have completely different needs, and the wrong guard can actually make symptoms worse. Here’s the framework our team used to evaluate the 8 picks above.

Soft vs Hard vs Hybrid: Understanding Mouthguard Types

Soft mouthguards use flexible EVA or thermoplastic materials. They’re comfortable, easy to fit, and ideal for light-to-moderate grinding. The downside is durability — heavy grinders can chew through a soft guard in 2-3 months. Most disposable and entry-level boil-and-bite guards fall into this category.

Hard mouthguards use rigid acrylic and are lab-fabricated to your exact bite. They last 2-5 years and handle heavy grinding forces without warping. The downside is comfort — hard acrylic can feel bulky and may take 2-3 weeks to adapt to. Dentist-made and lab-fabricated custom guards are typically hard acrylic.

Hybrid mouthguards combine a soft inner layer with a hard outer shell. They aim to deliver the comfort of soft guards with the durability of hard ones. The SAFEJAWZ above is a great example. Hybrids work well for both bruxism and sports, though they cost more than pure soft guards.

Signs You Actually Need a Mouthguard

Most grinders don’t realize they grind until damage is done. Here are the telltale signs our dentists flagged: morning headaches that fade by lunchtime, jaw soreness or tightness on waking, flattened or chipped tooth surfaces, partner reports of nighttime clicking, increased tooth sensitivity especially to cold, and visible wear on the inside of your cheeks from clenching.

If you have two or more of these symptoms, a properly fitted mouthguard will likely help. The American Dental Association estimates that 70% of bruxism-related tooth damage is preventable with the right guard.

Daytime vs Nighttime Mouthguards: What’s Different

Daytime guards are slimmer (1-3mm), sit lower-profile in the mouth, and allow clearer speech. They’re typically used for stress-related clenching during work or driving. The SISU Aero and Plackers disposable guards work well for daytime use.

Nighttime guards are thicker (3-6mm), more occlusal (they fully cover the biting surfaces), and prioritize protection over communication since you’re asleep. The DenTek Professional-Fit and HONEYBULL thick guards are designed primarily for nighttime wear.

When Custom Beats Boil-and-Bite

For occasional light grinding, a $15 boil-and-bite guard works fine. But custom lab-fabricated guards like enCore become cost-effective when you replace OTC guards more than twice a year. Custom is also better if you have dental work (crowns, bridges, implants), TMJ disorder diagnosed by a professional, or significant bite misalignment.

TMJ Mouthguards: Are They Different?

TMJ (temporomandibular joint) disorder is different from bruxism, though they often overlap. TMJ guards, sometimes called stabilization splints, are typically hard acrylic and cover either upper or lower teeth fully. They’re prescribed by dentists specifically for joint pain relief. None of the OTC mouthguards on this list are FDA-cleared specifically for TMJ — if you suspect TMJ, see a dentist before self-treating.

Cleaning and Maintaining Your Mouthguard

A mouthguard spends 8 hours a night in a warm, moist environment — exactly what bacteria love. Proper cleaning extends its life and protects your oral health. Here’s the cleaning routine our team settled on after 6 weeks of testing.

Rinse with cool water immediately after removal. Hot water can warp the material, especially with boil-and-bite guards. A 30-second rinse removes saliva and most surface bacteria.

Brush gently with a soft toothbrush and non-abrasive toothpaste or mild soap. Avoid whitening toothpastes — they’re mildly abrasive and can scratch the guard surface, creating places for bacteria to hide.

Deep-clean weekly by soaking for 15-30 minutes in a denture cleaner, diluted white vinegar (1:1 with water), or 3% hydrogen peroxide. Rinse thoroughly after any soak.

Air-dry completely before storing in a ventilated case. The antimicrobial cases that come with the DenTek and HONEYBULL guards help, but the guard still needs to be dry before going in.

Replace your guard when you see visible wear, warping, cracking, or holes. Boil-and-bite guards typically last 6 months with nightly use; lab-fabricated guards last 2-5 years; disposable guards last up to 3 nights each.

Frequently Asked Questions

Final Verdict: Which Mouthguard Should You Buy in 2026?

After 6 weeks of testing 8 of the best mouthguards on the market, three picks stand out for most people. The Plackers Grind No More wins for first-time users and anyone who wants hassle-free nightly protection. The DenTek Professional-Fit wins for buyers who want a custom-feel boil-and-bite guard at the lowest price. And the enCore Custom wins for heavy grinders who keep wearing out cheaper guards every few months.

For athletes, the Shock Doctor Gel Max and Venum Challenger deliver serious impact protection at a fair price, while the SISU Aero is the clear winner for braces wearers and slim-profile comfort. If you want the absolute best protection for combat sports, the SAFEJAWZ Black Fangz dual-layer design is hard to beat.

Whichever mouthguard you choose, wear it consistently. The American Dental Association notes that bruxism-related damage compounds over years, and a properly fitted guard can save you thousands in dental work down the road. If symptoms persist after 4-6 weeks of nightly wear, schedule a visit with your dentist to explore TMJ evaluation or prescription-grade options.
