About Mouthguards

The right mouthguards for MMA and boxing protect your teeth, lips and jaw when you spar, clinch or compete. Pro Boxing Store carries single and double guards, gel-fit models that mold to your teeth, and a storage case. Use this guide to match a guard to your training, check the fit and keep it clean.

Choosing Mouthguards for MMA and Boxing

Start with how much contact you take. Bag work and pad drills ask less of a guard than hard sparring or a fight. Then compare three things:

• Fit: A loose guard makes you clench to keep it in. Boil-and-bite guards shape to your teeth once softened, following the pack instructions.
• Protection: Look for a shock-absorbing frame or layered build over the front teeth.
• Breathing: A built-in breathing channel helps when you are tired and breathing hard.

Single vs Double Mouthguards

Most fighters wear a single (upper-arch) guard because it is easier to breathe and talk in. A double guard covers upper and lower teeth for extra coverage but takes more room in your mouth.

Type	Covers	Best for	Trade-off
Single	Upper teeth	Sparring, bag work, everyday training	Lower teeth uncovered
Double	Upper and lower teeth	Fighters who want more coverage	Bulkier; can feel restrictive
Boil-and-bite	Upper or both arches	A closer fit without a dentist visit	Must be molded correctly
Custom (dentist-made)	Made from a dental impression	A dentist-made fit	Higher cost and wait time

 

Mouthguard Fit and Size Guide

A good fit stays on your upper teeth without hard biting. After molding, check that it:

• Sits snug across your front and side teeth
• Does not press on your gums or cheeks
• Lets you breathe through your nose and mouth

Sizes are listed on each product page; the Gel Max Single shows an Adult size. If you wear braces, ask your orthodontist which guard is safe to use.

Which Mouthguard for Your Sport

Boxing

Boxing means repeated shots to the head, so choose a guard that stays seated for a full round and lets you breathe through it. Many boxers prefer a single guard for that reason. Pair it with boxing sparring gloves.

MMA

MMA adds clinches, takedowns and ground work, so a guard that does not shift while you grapple matters as much as impact protection. See our MMA gloves for the rest of your kit.

Muay Thai and kickboxing

Kicks, knees and elbows add side impacts to the jaw. Look for a frame that wraps the sides of the teeth, like the side walls on the Gel Nano Mouthguard.

Mouthguard Care and Replacement

Rinse your mouth guard after every session and brush it gently with a soft toothbrush, because water alone will not clear bacteria. Let it air-dry, then store it in a ventilated case away from heat, such as a hot car. Replace it when it cracks, wears thin or no longer fits snugly.

FAQ’s

Do you need a mouthguard for boxing?

Yes, for sparring and competition. A mouthguard cushions your teeth, lips and jaw against impact, and your gym may require one, so check its rules before you train.

Is a single or double mouthguard better for boxing?

Most boxers choose a single mouthguard because it is easier to breathe and talk in. A double guard covers lower teeth too, but it is bulkier and can feel restrictive.

Are boil-and-bite mouthguards good for MMA?

Yes. Boil-and-bite guards mold to your teeth for a closer fit than a stock guard, which helps them stay put during grappling. Follow the product instructions for heating and molding.

How do you clean a mouthguard?

Rinse it after every session, brush it gently with a soft toothbrush and mild soap, then air-dry it and store it in a ventilated case. Keep it away from heat.
