Key Takeaways

No, athletic mouthguards and aligner treatment generally do not interfere with each other when the mouthguard fits properly and is used during high-contact sports.
Clear aligners are worn for 20-22 hours a day to move your teeth, while a mouthguard protects them from sports-related impacts. Since they have different roles, the main thing is to use the right protection without disrupting your aligner routine.
Can You Safely Use an Athletic Mouthguard During Aligner Treatment?
Yes, you can generally use an athletic mouthguard during aligner treatment, but the right approach depends on your sport, mouthguard, and treatment plan.
Different types of mouthguards help protect teeth from blows that clear aligners are not designed to absorb. This is especially important in sports with regular contact. A systematic review found that dentofacial injuries affected about 28% of participants across the contact sports studied.
The mouthguard should feel secure without squeezing your teeth or irritating your gums. If it becomes uncomfortable, do not keep forcing it into place.
What Should You Do With Your Aligners Before a Game?

Remove your aligners before a game and wear a mouthguard instead. Keep that time as short as possible so you can stay close to your 20-22-hour daily wear schedule. Your dental professional can advise on the right mouthguard for your sport.
Do not wrap your aligners in a tissue or throw them into your gym bag. They can easily be lost or damaged. Put them in an ALIGNERCO Protective Case instead. This is also an easy way to manage clear aligners during sports without adding another thing to remember after the game.
How Do You Know If Your Mouthguard Still Fits Properly?
A good sports mouthguard should stay in place without feeling too tight. It should not hurt your teeth, press heavily on one area, or rub against your gums.
Your mouthguard can feel different as your treatment progresses because your teeth are gradually moving. If it suddenly feels tight, loose, or uncomfortable around certain teeth, have the fit checked rather than trying to force it into place.
When Should You Replace Your Mouthguard During Aligner Treatment?
Consider replacing your mouthguard if it becomes tight, loose, uncomfortable, damaged, or difficult to keep in place. A change in your tooth position can also make an older guard less suitable.
You do not need to replace it simply because time has passed. Its current condition and fit matter more.
A 2025 systematic review found that custom-made mouthguards may provide better fit and comfort than self-adapted options.
Choose the Custom ALIGNERCO Sports Mouthguard During Treatment
If you play high-contact sports regularly, having a mouthguard made for sports can make protection easier and more comfortable. The ALIGNERCO Sports Mouthguard is custom-fit, BPA-free, and 4mm thick for athletic protection.
It is made for practices, games, and other high-contact activities. It is there to protect your teeth during sports, not to replace your clear aligners.
Keep Your Smile Protected While You Stay on Track
Athletic mouthguards and aligner treatment can fit into the same routine because they do different jobs. Your aligners work throughout the day to move your teeth, while your mouthguard protects them when you're playing a high-contact sport.
Follow your treatment instructions, keep your trays safe when they are out, and pay attention to changes in mouthguard fit. A little planning can help you protect your smile without making aligner treatment harder to manage.
FAQs
1. Can I wear a sports mouthguard with clear aligners?
Yes, but not at the same time. You need to remove your aligners before putting in your mouthguard.
2. Do I wear my aligners under a mouthguard?
No. Remove your aligners before putting in your mouthguard, since wearing both together can affect the fit and protection.
3. Can a mouthguard affect aligner fit?
A poorly fitted mouthguard can cause pressure or discomfort, but a properly fitted one should not normally interfere with your aligner treatment.
4. Can sports damage clear aligners?
Yes. A hit to the face can crack or warp them, so remove them before the game and store them in a protective case.
