Review: Fits perfectly if you follow the instructions - Followed the instructions exactly the way it said and it’s the best fitting mouthguard I’ve ever had for MMA and BJJ. Fits perfect and I can’t remove it without my hands. Plus it doesn’t give you the gag reflex. Tried to remove it without my hands by just pushing with my lips and tongue but it’s stuck in there.
Review: Great guard for the price. - Pretty good. This is my 3rd one. I love how these stay in place during grappling, kick boxing, boxing, sparring ect.

## Questions & Answers

**Q: How do I clean my mouthguard?**
A: We suggest using OPRO cleaning tablets to ensure your mouthguard stays hygienically clean and minty fresh. Do not use toothpaste or anything abrasive as this will cause damage to your mouthguard.

**Q: Can I remold my OPRO mouthguard if it doesn’t fit perfectly the first time?**
A: Yes! Our Instant Custom and Self-Fit mouthguards (Bronze, Silver, Gold) are remoldable, provided that the fitting instructions are carefully followed. This allows you to refine the fit for maximum comfort and protection.

**Q: Our Precision-Fit Commitment**
A: At OPRO, our ultimate goal is to ensure you are satisfied with every OPRO product you purchase. We hope you are delighted with the fit of your purchase, but if you are not for any reason, our dedicated team is ready to assist you.

**Q: At what age would I change from a junior to an adult mouthguard?**
A: Our junior mouthguards are suitable for children up to age 10. When they reach the age of 10, we suggest that you use an adult mouthguard.

**Q: Do OPRO Self-Fit mouthguards contain latex or BPA?**
A: No, all of our mouthguards are free from latex, BPA, and phthalates.

### ⭐⭐⭐⭐⭐ Great guard for the price.
*by C***Y on January 15, 2026*

Pretty good. This is my 3rd one. I love how these stay in place during grappling, kick boxing, boxing, sparring ect.

### ⭐⭐⭐⭐ Not great for competition
*by D***R on January 7, 2026*

Got the mouth pc last second for a mma fight had coming up. Used it and it honestly worked not as good as expected. I felt like it wasn't as large as others I have had and in general covered less of my teeth. I had some cuts on my gums and in my mouth after the fight. What I do like about it however is the colors and how I was able to reboil for a better fit. Good mouth guard but not for competition.
