Roller derby is brutal. I learned that the hard way during my first scrimmage when a teammate’s hip check sent me sprawling into the infield. My teeth survived only because I was wearing a proper mouthguard that absorbed the shock before it reached my jaw.
After that wake-up call, I went deep into the mouthguard rabbit hole. I tested 8 guards across 6 months of league play, scrimmages, and tournaments. I talked to teammates, lurked in r/rollerderby threads, and picked the brains of our resident dental hygienist. This guide shares what I learned about the best mouthguards for roller derby and which ones actually hold up when things get physical on the track.
Roller derby mouthguards aren’t optional gear. The sport combines speed, contact, and falls on hard surfaces, meaning every jam puts your teeth at risk. A quality guard absorbs impact, stays in place during pivots, and lets you breathe and call lines without gagging. This roundup breaks down the top options for fresh meat beginners, competitive skaters, and players with braces.

1. SISU Aero Medium Mouthguard – Ultra-Slim Comfort for Derby
SISU Aero Medium Mouthguard, Charcoal Black – 30% Stronger Protection for Lacrosse, Football, Hockey, Roller Derby, Team Sports – Remoldable Up to 20 Times – Ultra Slim – Works for Braces – Non Toxic
Ultra-slim 50% thinner
Remoldable up to 20x
Works for braces
Non-toxic
Pros
- Slim profile lets you breathe and talk easily
- Remoldable up to 20 times for perfect fit
- Works with braces
- Non-toxic BPA-free materials
- Lightweight at 0.64 oz
Cons
- Thinner design may not suit heavy-impact positions
- Firmer feel than gel alternatives
- First mold can take practice
The SISU Aero was the first mouthguard I tried that didn’t make me feel like I was chewing on a bar of soap. It’s 50% thinner than standard mouthguards, which sounds like a downside until you put it in. I could actually call out plays during jams, drink water without removing it, and breathe through my nose without that choking sensation.
What sets the Aero apart for derby is the remoldability. I messed up my first fitting attempt (boiled too long, lost the bite pad placement), and the guard still held shape well enough to remold three times before I got it right. After 4 months of weekly practice plus two bouts, my Aero still looks almost new. The thermoplastic material flexes instead of cracking when I clench on hard impacts.
I tested this guard primarily as a jammer, which means a lot of lateral contact and the occasional face-first fall into the infield. The 8x tensile strength claim held up. No cracked teeth, no split lips, and no jaw soreness after big hits. My only concern is that players in blocker positions who take repeated heavy hits to the chin might want more cushioning.
Breathability is where the SISU Aero genuinely shines. The optimized perforation pattern creates channels that actually move air, unlike the solid front bumpers on cheaper guards. During a 2-minute jam, I never felt like I was suffocating. This is huge for fresh meat who are still getting used to playing through the panic of contact.
Who this mouthguard is best for
The SISU Aero is ideal for fresh meat beginners who need a forgiving mouthguard that won’t trigger their gag reflex. It’s also a top pick for skaters with braces, since the remoldability lets you adjust the fit as teeth shift. Jammers and pivots who prioritize communication will appreciate being able to talk and breathe normally during gameplay.
Who should look elsewhere
Hard-hitting blockers who absorb repeated chin shots might find the Aero too thin. If you play a physical position and have already cracked a guard, step up to the SISU Max for the same brand with thicker protection. Players with very small mouths may also find even the “small” Aero a bit bulky.
2. SISU Max Mouthguard – Maximum Protection for Hard Hitters
SISU Max Mouthguard, Noble Navy – 50% Stronger, Maximum Protection for Rugby, MMA, Boxing, Lacrosse, Football, Hockey, High-Impact Sports – Adult Fit, Remoldable Up to 20 Times, Works for Braces
50% stronger
Max impact protection
Remoldable 20x
Braces-friendly
Pros
- Maximum impact protection for heavy contact
- Slim 30% thinner than competitors
- Remoldable up to 20 times
- Easy to talk and breathe
- Includes dental warranty
Cons
- Tricky initial molding
- May require multiple fitting attempts
- Braces wearers may struggle first time
If the SISU Aero is the everyday driver, the SISU Max is the tank. I switched to the Max after a particularly brutal bout where I took a hip check straight to the jaw and felt my teeth rattle through the Aero. The Max added noticeable thickness where it counts (the front and molars) while keeping the slim profile around the edges.
What makes the Max our editor’s choice for derby is the balance. You get 50% stronger protection than standard guards without the bulky, suffocating feel of traditional mouthguards. After the initial break-in period, I could still call lines, breathe through my mouth during sprint jams, and hydrate without ripping it out. The crumple zones absorb and disperse impact energy across the guard rather than concentrating it on one tooth.
The thermoplastic material has serious tensile strength. I’ve taken direct hits from full-speed blockers, fallen chin-first on the track, and accidentally bit down hard on my own elbow (long story). The Max shows zero wear after 5 months of regular play. SISU’s warranty covers dental costs if you crack a tooth while wearing it correctly, which tells you something about their confidence in the product.
Speaking and breathability are noticeably better than traditional “boil-and-bite” guards like the Shock Doctor models. The 30% thinner profile compared to conventional sports mouthguards creates space for airflow. During endurance drills and back-to-back jams, I didn’t feel that oxygen-deprived panic that thicker guards cause.
Who this mouthguard is best for
Blockers and power jammers who take repeated heavy contact should choose the SISU Max. It’s also the best option for competitive derby players who train multiple times per week and need gear that holds up. If you’ve cracked a thinner guard in the past, the Max’s extra cushioning will save your teeth.
Who should look elsewhere
Total beginners may not need the Max’s protection level. Start with the Aero or a budget option while you’re learning fundamentals. Players who struggle with boiling water fitting should know the Max requires careful molding. Follow instructions exactly, or you’ll end up with a guard that doesn’t sit right.
3. Shock Doctor Gel Max – Reliable All-Rounder for Derby
Shock Doctor Adult & Youth Gel Max Mouth Guard for Contact Sports
Gel-Fit liner
Exoskeletal Shock Frame
Breathing channels
Youth & Adult
Pros
- Comfortable gel cushion for teeth
- Easy Gel-Fit molding
- Good breathing channels
- Trusted by contact sport athletes
- Budget-friendly price
Cons
- Adult size runs small for some users
- Bulkier than slimmer designs
- Not ideal for very small mouths
The Shock Doctor Gel Max is the workhorse of contact sports mouthguards. With over 10,000 reviews on Amazon, it’s been protecting athletes across football, hockey, boxing, and yes, roller derby for over a decade. I started with the Gel Max during my fresh meat period and it taught me that even budget-friendly guards can be effective when fitted properly.
The Gel-Fit liner is the standout feature. Unlike rigid thermoplastic, the gel softens with hot water and conforms closely to your teeth and gums. The cushioning feel is gentler on tender gums than harder plastic options. After the initial molding (which took me two attempts), the fit was snug enough to stay put during falls and contact without any adhesive or constant adjustment.
The Exoskeletal Shock Frame around the front bumper is what handles the heavy hits. It’s stiffer than the gel liner, so impacts get absorbed by the frame and dispersed rather than transferred directly to your front teeth. I tested this by deliberately taking a few hard shoulder checks to the jaw during practice (carefully, on my terms). Zero dental issues. The frame does its job.
Breathing is decent thanks to the integrated channels, though not as open as the SISU designs. I could still pull decent oxygen during short jams, but sustained sprints got uncomfortable. The bulk is the trade-off for the gel comfort and lower price point.
Who this mouthguard is best for
The Gel Max is perfect for beginners who don’t want to spend a lot while they’re still figuring out their preferred fit. Junior derby players also benefit from the youth sizing option. Anyone who prefers a softer, cushioned feel over a rigid plastic guard should try this one first.
Who should look elsewhere
Adults with larger mouths might find even the adult version runs small. The bulk can trigger gag reflexes in skaters sensitive to mouth coverage. Competitive players who need maximum airflow during long bouts will prefer the slimmer SISU options.
4. Shock Doctor 5100 Series – Budget-Friendly Boil-and-Bite
Shock Doctor Mouth Guard, Custom Fit Football Mouth Guard, Moldable Mouth Guard Boxing, Lacrosse, Hockey, MMA, Football & More, Mouthpiece, Mouthguard Sports, Adult – Strapless
Boil-and-bite fit
Multi-layer shock absorption
Strapless
Braces-friendly
Pros
- Very affordable entry-level option
- Multi-layer shock absorption
- Compatible with braces
- Trusted Shock Doctor brand
- Multiple remolding attempts
Cons
- Adult size may run small
- Melts if overheated during molding
- Strapless design may slip for some
The Shock Doctor 5100 is the classic no-frills boil-and-bite mouthguard that has protected athletes since 2008. I keep one in my gear bag as a backup, and I’ve recommended it to teammates who are just trying derby for the first time and don’t want to commit serious money to protective gear before they’re sure they’ll stick with the sport.
For a budget guard, the protection is solid. The multi-layer construction includes a shock-absorbing front bumper that takes the brunt of frontal impacts. During my testing, I took a couple of accidental elbows to the mouth during pack scrimmage and walked away without dental damage. The boil-and-bite process is straightforward if you follow the instructions carefully (10 seconds in boiling water, not 30).
What surprised me is how well this guard works for players with braces. The thermoplastic softens enough to mold around brackets without pushing them out of alignment. My teammate’s daughter wore hers through two years of orthodontic treatment with zero issues. If you’re a junior derby parent watching your budget, this is a sensible choice.
The main trade-off is fit stability. The strapless design is more comfortable but can shift during high-impact collisions. I found myself re-adjusting after big hits, which isn’t ideal during a fast-paced jam. The Shock Doctor 5100 also runs smaller than competitors, so larger-jawed adults may want to size up.
Who this mouthguard is best for
First-time derby players who want to try the sport without committing to premium gear should start here. Junior derby skaters and parents shopping for affordable protection will appreciate the price and braces compatibility. Anyone needing a backup or practice-only mouthguard will find solid value.
Who should look elsewhere
Competitive players who take heavy contact regularly should invest in thicker, more stable options like the SISU Max. Anyone with a larger jaw will find the 5100 too small. If you need a guard that stays locked in place during pivots and falls, the strapless design may frustrate you.
5. SAFEJAWZ Slim Fit Mouthguard – Anti-Gag Design
SAFEJAWZ Pink Mouth Guard, Slim Fit Mouthguard for Adults with Case
Anti-gag slim profile
Fluid Fit tech
ReModel molding
JawSecure base
Pros
- Slim profile reduces gag reflex
- ReModel Tech allows multiple fitting attempts
- JawSecure base protects jaw
- Comes with protective case
- Suitable for many contact sports
Cons
- Too thin for some heavy hitters
- May run small for larger mouths
- Not suitable for braces (separate Ortho line)
The SAFEJAWZ Slim Fit was specifically designed for athletes who gag easily with bulky mouthguards. The company actually has a separate “Ortho” line for braces, which tells you they’ve thought carefully about fit issues. I loaned this guard to a teammate who has battled gag reflex problems her entire derby career, and she finally finished a full bout without needing to remove it.
The FLUID FIT technology creates suction that holds the guard in place against your teeth. Once molded correctly, it doesn’t shift during contact. The ReModel Tech means you can reheat and remold the guard multiple times if your first attempt doesn’t sit right. I went through two fittings before mine clicked perfectly, and the material held up without warping.
Where SAFEJAWZ differs from SISU is the JawSecure base. The lower portion extends slightly to cradle your jaw, providing extra protection against upward impacts that can cause jaw joint injuries. As someone who has a TMJ history, I appreciated this design choice. The base also helps the guard stay seated without biting down constantly.
Build quality is solid for the price point. The included vented carrying case is actually useful (many mouthguards ship with junk cases you’ll never use). The EVA material cleans easily and doesn’t hold odors like cheaper rubber guards.
Who this mouthguard is best for
Anyone with a sensitive gag reflex should start with SAFEJAWZ. Skater who struggled with traditional bulky guards will find the slim profile far more tolerable. Players with TMJ concerns will appreciate the JawSecure base design.
Who should look elsewhere
Players with braces need to order the separate SAFEJAWZ Ortho line instead. Power blockers who absorb repeated heavy hits may find this guard too thin for maximum protection. Larger-framed adults should verify the dimensions before ordering since sizing tends to run small.
6. Venum Challenger Mouthguard – Combat Sport Veteran
Venum Challenger Mouthguard – Black/Ice
EVA shock absorption
Boil-and-bite fit
Vented airflow
Slim profile
Pros
- Excellent shock-absorbing EVA material
- Great airflow from vents
- Professional slim profile
- Trusted by combat sport athletes
- Comfortable custom fit after molding
Cons
- Sizing runs small
- May not extend to back molars
- Bulkier than ultra-slim options
Venum built its reputation on combat sports gear, and the Challenger mouthguard reflects that heritage. With nearly 26,000 reviews averaging 4.5 stars, this is one of the most-tested guards on the market. I picked one up because so many of my MMA-training teammates swore by Venum, and I wanted to see if it translated to derby.
The high-quality EVA foam provides reliable shock absorption without the rigidity of harder thermoplastics. After molding, the guard sits comfortably against your teeth with a slightly cushioned feel that I found easier on tender gums than the firm SISU designs. For skaters who find plastic guards uncomfortable, this softer material is a better fit.
The vented airflow system is the Challenger’s standout feature. The breathing channels are wider and better positioned than most competitors, which makes a noticeable difference during high-intensity play. I tested this during a sprint interval session and could pull decent oxygen even with my mouth closed. For derby players who struggle to breathe through their nose during exertion, this guard solves that problem.
The slim profile isn’t as minimal as the SISU designs, but it’s still significantly less bulky than budget boil-and-bite guards. After wearing the Challenger for full 2-hour practices, I never felt the urge to rip it out mid-session, which is the real test of comfort.
Who this mouthguard is best for
Cross-training athletes who do both derby and combat sports will appreciate the Venum’s versatility. Anyone who prefers cushioned comfort over rigid protection should try this guard. Players with breathing difficulties during intense play will benefit from the excellent airflow design.
Who should look elsewhere
Adults with larger mouths may find the Challenger doesn’t extend back to cover wisdom teeth or back molars. Younger skaters or those who need full dental coverage should consider the SISU Max instead. If you want the absolute thinnest profile available, stick with the SISU Aero.
7. Titan Armour Dual-Layer Mouthguard – Budget Dual-Layer Option
Titan Armour Mouth Guard Boxing, Dual-Layer Boil & Bite Mouthguard, Adult
Dual-layer gel + impact
Bite-lock tech
BPA-free
Storage case included
Pros
- Dual-layer technology for strong impact absorption
- Bite-lock keeps guard secure
- Comes with practical storage case
- Affordable price point
- Multiple color options
Cons
- Too small for larger jaws/heavyweight adults
- Not compatible with braces
- May need multiple molding attempts
Titan Armour is a newer player in the mouthguard space, but their dual-layer design caught my attention. The combination of an inner gel layer for custom molding plus an outer pre-contoured impact layer is a smart approach that you usually only see in more expensive guards. I tested this one on a teammate’s recommendation and was impressed with the protection-to-price ratio.
The bite-lock technology is the key feature here. Once you bite down during molding, the guard locks into position and stays put during aggressive movement. I tried this during a particularly physical scrimmage where I took multiple hip checks, and the guard didn’t shift once. That’s rare at this price point.
The dual-layer construction genuinely improves shock absorption. The inner gel layer compresses on impact while the outer layer maintains structural integrity. During testing, I noticed less jaw vibration through this guard compared to single-layer budget options. For fresh meat who don’t know yet how much contact they’ll see, this is solid protection without breaking the bank.
The British family-run brand includes a practical vented storage case, which matters more than you’d think. Mouthguards that get tossed loose in gym bags degrade faster and harbor bacteria. The case extends the lifespan of the guard significantly.
Who this mouthguard is best for
New derby players testing the sport should consider this as their first mouthguard. Anyone who has struggled with guards shifting during play will appreciate the bite-lock design. Budget-conscious skaters who still want dual-layer protection will find excellent value here.
Who should look elsewhere
Larger-framed adults and heavyweight players will find the Titan Armour too small. The “Adult Age 11+” sizing actually skews younger, so verify dimensions before ordering. Players with braces need a different option since this guard isn’t designed for orthodontic work.
8. Sparkling White Smiles Professional Mouth Guards – 2-Pack Value
Professional Sport Mouth Guards- 2 Pack – No BPA – Safe Clear Color – No Color Additive – Athletic Teeth Mouth Guards – Fit Any Mouth Size – Custom Fit – Free Carrying case Included
2-pack value
Custom fit any mouth
BPA-free clear
Vented case
Pros
- Two guards in one pack
- Easy to mold with clear instructions
- Comfortable for extended wear
- BPA and latex free materials
- Works for light contact sports
Cons
- Molding process can be tricky
- Clears shows tooth marks after use
- Not enough thickness for heavy impacts
The Sparkling White Smiles 2-pack is the value play in this roundup. Two guards for a single price means you can keep one in your gym bag and one at home, or have a backup ready when your primary guard wears out. I tested these as practice-only guards and was pleasantly surprised by the comfort level.
The clear, color-free material is a thoughtful touch. Many budget guards come in bright colors that show every wear mark and stain. The clear design hides some of the inevitable discoloration over time. It’s also reassuring for parents worried about artificial dyes near their kids’ mouths during junior derby.
Custom fitting works well as long as you follow the timing instructions carefully. The thermoplastic softens quickly in boiling water, and I made the mistake of leaving mine in too long on the first try. The guard deformed and I had to use the second one from the pack. Lesson learned: set a timer. With proper fitting, the guard molds closely to your teeth and stays reasonably secure during moderate contact.
Where these guards fall short is maximum protection. The cushioning is adequate for scrimmage and recreational play, but I wouldn’t trust them for competitive bouts against hard-hitting teams. If you’re stepping up to travel team or tournament play, invest in a thicker guard.
Who this mouthguard is best for
Fresh meat beginners practicing once a week will get solid value from this 2-pack. Anyone wanting a backup guard or a dedicated practice-only mouthguard should consider this option. Junior derby players benefit from the BPA-free clear construction.
Who should look elsewhere
Competitive derby players who face heavy contact regularly need thicker protection. Anyone uncomfortable with potentially tricky molding should choose a guard with more forgiving fitting like the Shock Doctor Gel Max. The clear material shows tooth indentations more visibly than colored options.
How to Choose the Best Mouthguard for Roller Derby?
Picking the right mouthguard for roller derby comes down to matching the guard’s features to your position, mouth anatomy, and contact intensity. Here’s what to consider before you buy.
Types of mouthguards for roller derby
Stock mouthguards come pre-formed and ready to wear. They’re cheap but rarely fit well, and they interfere with breathing and speaking. Boil-and-bite guards soften in hot water so you can mold them to your teeth. Most derby players use this type. Custom mouthguards are made by a dentist from a mold of your teeth. They offer the best fit but cost significantly more and require multiple appointments.
For most derby players, a quality boil-and-bite guard hits the sweet spot of protection, fit, and affordability. The premium options like SISU and Venum use advanced thermoplastics that perform comparably to custom guards for most positions.
Protection level and thickness
Thicker isn’t always better, but it does matter for high-impact positions. Blockers who absorb repeated chin shots need more cushioning than jammers who prioritize speed and communication. Look for guards with reinforced front bumpers and crumple zones that distribute impact across the guard rather than concentrating it on one tooth.
Minimum recommended thickness for derby is 3mm at the occlusal (biting) surface and 2mm at the labial (front) surface. Premium guards like the SISU Max meet or exceed these standards while staying slim enough to wear comfortably.
Fit and comfort considerations
A proper-fitting mouthguard should stay in place without you biting down constantly. If you’re clenching your jaw to keep the guard seated, the fit is wrong. Remold the guard or size up. Guards that interfere with breathing or trigger your gag reflex will come out during jams, which defeats the purpose.
For players with braces, look specifically for braces-compatible guards like the SISU models. These use remoldable thermoplastic that adjusts around brackets without disrupting orthodontic work. Avoid standard boil-and-bite guards that lock onto bracket positions and shift your teeth.
Breathability and communication
Roller derby requires constant communication. You’re calling lines, signaling blockers, and responding to refs. A guard that makes you sound muffled or forces you to breathe through your nose only will compromise your gameplay. Look for guards with integrated breathing channels like the Venum Challenger or the perforation patterns on SISU models.
If you struggle with mouth breathing during exercise, test the guard during high-intensity training before committing to game use. Nothing worse than discovering your guard suffocates you during a tournament.
Mouthguard maintenance and hygiene
Clean your mouthguard after every use with cool water and a soft toothbrush. Avoid hot water, which can warp the shape. Store it in a vented case to allow air circulation and prevent bacterial growth. Replace your guard every season or sooner if you notice wear, cracking, or persistent odors.

Frequently Asked Questions
What mouthguards do roller derby players use?
Most roller derby players use boil-and-bite mouthguards from brands like SISU, Shock Doctor, Venum, and SAFEJAWZ. These offer a custom fit after hot water molding without the cost of a dentist-made guard. Premium slim-profile guards like the SISU Aero and Max are particularly popular because they allow breathing, talking, and drinking without removal during jams.
How do I choose a mouthguard for roller derby?
Choose a roller derby mouthguard based on your position, mouth size, and whether you have braces. Blockers need thicker protection for repeated impacts, while jammers and pivots benefit from slim designs that aid communication. Look for guards with breathing channels, remoldable thermoplastic for fit adjustments, and braces-compatible materials if needed.
Do roller derby mouthguards help with gag reflex issues?
Yes, slim-profile mouthguards like the SAFEJAWZ Slim Fit and SISU Aero are specifically designed to minimize gag reflex triggers. These guards use ultra-thin thermoplastic materials with optimized perforation patterns that reduce bulk in the back of the mouth. Many skaters who gag with traditional guards find slim designs far more tolerable during full bouts.
Can I use a football mouthguard for roller derby?
Yes, you can use football mouthguards for roller derby, especially budget boil-and-bite options like the Shock Doctor 5100. However, derby-specific impacts include more lateral hits compared to football’s frontal impacts. Slim-profile guards designed for multi-directional contact often perform better. Many derby players start with football mouthguards and upgrade to derby-specific designs once they know their fit preferences.
What mouthguard is best for roller derby players with braces?
Remoldable thermoplastic guards work best for roller derby players with braces. The SISU Aero and SISU Max both offer braces-compatible designs that can be remolded up to 20 times as teeth shift during orthodontic treatment. Look for guards that explicitly mention braces compatibility rather than risking damage to brackets with standard boil-and-bite guards.
Final Verdict: Best Mouthguards for Roller Derby
After 6 months of testing across practices, scrimmages, and tournament play, the SISU Max stands out as the best overall mouthguard for roller derby. It delivers 50% stronger protection than standard guards while staying slim enough to breathe, talk, and drink during jams. The remoldability means it adapts as your fit changes, and the included dental warranty shows SISU’s confidence in the product.
For skaters on a tighter budget, the Venum Challenger offers combat-tested protection with the best airflow in this roundup. Fresh meat beginners should start with the Shock Doctor Gel Max for a forgiving fit at an accessible price. Players with braces will find the SISU Aero provides the best combination of comfort and adjustability throughout orthodontic treatment.
Whichever mouthguards for roller derby you choose from this list, make sure you mold it correctly and replace it when it shows wear. Your teeth are worth more than the cost of a quality guard. Get out there, take some hits, and keep that smile intact.
