Mouthguard Buying Guide — How to Choose the Right Gum Shield for Martial Arts

A mouthguard is one of the most important — and most overlooked — pieces of protective equipment for any contact sport. The right mouthguard protects your teeth, jaw and reduces concussion risk. This guide covers everything you need to choose the right one for your training.

Do I Need a Mouthguard for Martial Arts?

Yes — a mouthguard is non-negotiable for any sparring or contact training. Without one, a single strike to the jaw can chip or break teeth, cause jaw injuries or increase concussion risk. Most clubs require a mouthguard for sparring, and all combat sports competitions mandate one.

Types of Mouthguard

Boil and Bite (Self-Fit)

The most common type for martial arts training. You soften the guard in boiling water, then bite into it to create a custom impression of your teeth. Offers a much better fit than a stock guard and good protection for regular training. Available at a range of price points — higher-end boil and bite guards (like OPRO Gold and Platinum) offer near-custom fit quality.

Custom-Fit (Dentist-Made)

Made from an impression of your teeth taken by a dentist. Offers the best possible fit, comfort and protection. Recommended for serious competitors and anyone who spars regularly. Higher cost but significantly better protection and comfort than self-fit guards.

Stock / Ready-Made

Pre-formed guards that require no moulding. The least expensive option but the poorest fit — they can be uncomfortable, restrict breathing and offer less protection. Not recommended for regular training.

Double Mouthguard

Covers both upper and lower teeth. Rarely used in martial arts as they restrict breathing significantly. Occasionally required for specific combat sports.

What to Look for in a Mouthguard

• Fit — The most important factor. A well-fitted guard stays in place without biting down, allows normal breathing and doesn't gag you.
• Thickness — Thicker guards absorb more impact but can be bulkier. Thinner guards are more comfortable but offer less protection. Modern materials allow thin guards with excellent protection.
• Breathing — You should be able to breathe normally with the guard in. This is critical for high-intensity training.
• Communication — You should be able to speak clearly enough to communicate with your coach during training.
• Dental warranty — Premium guards from OPRO and SISU come with dental warranties — a sign of confidence in their protective capability.

Mouthguards for Braces

Standard boil and bite guards are not suitable for braces — the moulding process can damage the brackets. OPRO produce a specific braces mouthguard (OPRO Gold Braces) designed to fit comfortably over dental braces without causing damage.

Which Mouthguard Brand Should I Choose?

OPRO

OPRO are the world's leading mouthguard brand — trusted by professional fighters, rugby players and Olympic athletes worldwide. Their self-fit range covers every level:

• OPRO Bronze — Entry-level self-fit guard. 11 moulding fins for a secure fit. CE approved. Good value for beginners.
• OPRO Silver — Improved fit with antimicrobial protection. CE approved with up to £12,500 dental warranty.
• OPRO Gold — Superior fit with anatomical fins that mould to each individual tooth. CE approved with up to £15,000 dental warranty.
• OPRO Platinum — Elite self-fit guard with 13 anatomical fins and dual-layer construction. CE approved with up to £17,500 dental warranty.
• OPRO Snap-Fit Gen4 — No boiling required — instant fit for those who want convenience. Available in kids and adult sizes.
• OPRO Gold Braces — Specifically designed for wearers of dental braces.

SISU

SISU take a different approach — ultra-thin guards (1.6–2.4mm) made from a perforated, high-strength material that allows natural breathing and speaking. Despite being significantly thinner than traditional guards, SISU's Diffusix technology distributes impact across the surface for excellent protection.

• SISU Aero (1.6mm) — Ultra-slim, 50% thinner than standard guards. Up to $50,000 dental warranty. Ages 7+.
• SISU GO (1.6mm) — Entry-level SISU guard. Perforations allow natural airflow. Up to $50,000 dental warranty.
• SISU Max (2.4mm) — 30% thinner than conventional guards but 50% stronger material. Up to $50,000 dental warranty. Ages 11+.
• SISU 3D — Pre-formed shape for easier fitting. Variable thickness for comfort and protection. Works with braces.

OPRO vs SISU — Which Should I Choose?

• Choose OPRO if you want a traditional boil-and-bite guard with proven protection, CE approval and a UK dental warranty. The Gold and Platinum tiers offer near-custom fit quality.
• Choose SISU if you prioritise breathing and communication during training — their ultra-thin design is particularly popular with grapplers and high-intensity trainers who find traditional guards restrictive.

Caring for Your Mouthguard

• Rinse with cold water before and after use
• Clean with a toothbrush and toothpaste or mouthguard cleaner after each session
• Store in a ventilated case — never in a sealed bag
• Keep away from heat — hot water or direct sunlight can distort the shape
• Replace when the guard shows signs of wear or no longer fits securely

Summary — Choosing the Right Mouthguard

• Beginners: OPRO Bronze or Silver — affordable, CE approved and a good fit
• Regular training: OPRO Gold or SISU Aero — near-custom fit with excellent protection
• Competition / serious sparring: OPRO Platinum or SISU Max — elite protection with high dental warranties
• Braces wearers: OPRO Gold Braces or SISU 3D
• Grapplers / high-intensity training: SISU — ultra-thin design allows natural breathing and speaking
