Clear Aligners, Sports & Mouthguards: A Dad’s Guide
This is a contributed post.
If you’re like a lot of active dads, you’ve probably wondered: can I still play pickup basketball, train for that half-marathon, or hit the mat for jiu-jitsu while wearing clear aligners?
Let’s be clear—aligners are powerful tools for improving your smile. But they’re not designed to take a punch, a ball, or even an accidental elbow. That’s where mouthguards come in.
In this guide, you’ll learn:
Why clear aligners don’t replace mouthguards
When you absolutely need a guard—and what kind
How to build easy routines to protect your teeth and model good habits for your kids
Why dental protection matters when you’re active
Even if you’re not in a full-contact sport, the odds of taking a stray elbow or ball to the face are higher than you think. Sports like basketball, soccer, mountain biking, and martial arts all carry real risk for chipped teeth, soft tissue damage, or worse.
A properly fitted mouthguard helps absorb the shock from these impacts, spreading out the force so your teeth—and jaw—are less likely to suffer. The ADA MouthHealthy mouthguard overview strongly recommends guards for a wide range of sports, not just boxing and hockey.
It’s not just about pain. Dental injuries can mean time off work, emergency procedures, and thousands in unexpected bills. Compared to that, a $30 mouthguard feels like a steal. And if you’re already thinking about braces protection for your son in sports, it’s worth making sure you’re protected, too.
You’re also setting an example. If your kids see you treating your smile like it’s worth protecting, they’ll be more likely to do the same—on the field and in the bathroom.
Clear aligners and how they behave in sport
Clear aligners are custom plastic trays that gently move your teeth over time. They’re effective, subtle, and easy to remove—but they aren’t built to cushion impacts. In fact, if you get hit while wearing them, those sharp plastic edges could make an injury worse.
Most treatment plans require you to wear aligners 20–22 hours a day. That leaves just enough time for eating, brushing, and—if planned correctly—high-risk sports. A short, orthodontist-approved break from trays for a game can still keep you on track.
Low-contact sports like jogging, Pilates, or yoga? You may be fine keeping trays in. But for anything involving speed, sticks, or bodies crashing together, orthodontists usually recommend taking them out and using a proper guard instead.

Wondering if you can wear a mouthguard over your aligners? Opinions vary, but most orthodontists prefer trays out, guard in—especially for hard-hitting sports. Always ask your provider what’s best for your case.
When you absolutely need a mouthguard
Some sports carry too much risk to go in unprotected. If your activity involves speed, contact, or projectiles—think football, rugby, hockey, or martial arts—a guard isn’t optional.
That’s not just our take. The AAPD policy on sports-related orofacial injuries highlights the need for properly fitted guards to prevent tooth and jaw injuries. While the guidelines focus on kids, the principles apply to adults just as much.
Need a simple rule of thumb? Try this traffic-light system:
🟢 Low-risk (trays in OK): jogging, yoga, stretching
🟠 Medium-risk (consider guard): soccer, baseball, basketball
🔴 High-risk (guard mandatory): rugby, hockey, martial arts, skateboarding
Maybe your league is “just casual” or you’ve never been hurt before—but accidents happen fast. A flying elbow doesn’t care if you’re playing pickup or playoffs.
Choosing a mouthguard when you wear clear aligners
There are three main types of mouthguards:
Stock: pre-formed and ready to wear. Cheap, but poor fit.
Boil-and-bite: softened in hot water and moulded to your teeth. Good balance of fit and cost.
Custom: made by your dentist. Best fit and protection—but also the priciest.
If you have braces, boil-and-bite guards often don’t work well because teeth move and brackets get in the way. But with aligners, you may be able to remold a boil-and-bite guard as your teeth shift—or simply remove your trays during high-contact sports.
Need help deciding when to wear your trays and when to swap in a guard? This clear aligners and sports mouthguard guide breaks down use cases, materials, and scenarios to discuss with your orthodontist.
Whatever route you choose, a guard should fit snugly, not wobble, and not press painfully against your teeth or gums. If it feels off—or like it’s pulling your trays—check in with your provider.
Game-day routines for dads and kids
Before the game, build a quick checklist:
Decide if aligners are staying in or coming out
Pack your aligner case and guard case
Check your guard for damage or warping
Brush or rinse if possible before putting anything in your mouth
After the game, your job isn’t done. Pop your trays back in as soon as you can, give your mouthguard a rinse, and do a quick self-check for soreness, cuts, or tooth pain. It’s also a good time to clean up using non-toxic oral health essentials so your aligners don’t trap bacteria.
Better yet—make it a family habit. If your kids play too, do these routines side by side. A guard in one hand and a case in the other becomes just as normal as tying your cleats.
Bringing it all together
Clear aligners don’t mean giving up your sport. With the right plan, you can stay active, protect your smile, and keep your treatment moving forward.
Start small: pick one high-risk sport you play and check whether you’re using the right protection. Talk to your orthodontist about mouthguard options. And next time you pack your gym bag, toss in both your trays and your guard—because a strong, healthy smile is worth the effort.
