Mouthguards For Combat Sports
Combat sports — boxing, MMA, BJJ, karate, judo, and Muay Thai — put the mouth and jaw under loads you rarely see in other sports. Direct strikes, clinches, takedowns, and ground exchanges all create situations where the teeth, lips, and jaw are exposed. A properly fitted custom mouthguard is one of the more important pieces of protective gear a combat athlete can own.

Pre-season fittings
At a glance: Thicker than a field-sport guard, full molar coverage, fitted to the bite. Heavy clenching during sparring shortens the life — expect to replace a hard-trained guard yearly. If you also clench at night, ask about a separate nightguard.

Common injuries
Common dental injuries in combat sports
The mix of injuries varies by discipline, but most combat athletes will be familiar with at least some of the following:
If a strike has knocked a tooth out, follow our knocked-out tooth first aid and get to a dentist quickly — the first 30 to 60 minutes are the most important. For other gym-floor injuries, our sports dental injury guide covers what to do.
Why custom
Why combat athletes need a higher standard of fit
Combat sports differ from field sports in three ways that matter for mouthguards:
A custom guard is made from layered EVA at a thickness that absorbs and disperses impact across the bite, rather than transferring it through one or two teeth. The fit hugs the molars as well as the front teeth, which is essential for grapplers — a loose guard ends up on the mat in the middle of a roll.
Off-the-shelf boil-and-bite guards have a place for casual sparring or beginners, but as training volume and intensity increase, the limits of a stock guard become obvious. Our custom vs boil-and-bite page covers the trade-offs in detail.

Who it suits
Who this suits
A custom mouthguard suits combat athletes including:
If you have crowns, veneers, implants, or recently completed orthodontic treatment, a custom guard is the more reliable choice. Combat athletes in active braces should also see our mouthguards with braces page.
Appointment
What to expect at the appointment
Scan or impression
We start with a digital scan or quick impression of your teeth. For combat athletes we usually also capture the bite so the guard sits in a way that does not interfere with clenching.
Fabrication
The guard is made from pressure-laminated EVA. Combat athletes often prefer a slightly thicker guard with full molar coverage. We can also discuss dual-arch guards if you have particular concerns.
Fitting and adjustments
At the fitting visit we check the guard hugs the teeth without lifting during jaw movements. Minor trims and adjustments happen on the day.
Review
We check the guard at your next check-up and clean. Bring it along — wear and tear, bite marks, and material breakdown are all easier to spot under the dental light.
Care & replacement
Replacement and care
Combat athletes who train multiple times a week often chew their guards during heavy rounds — that is normal and expected. Most adult guards still last a year or more, but heavy bite marks or visible thinning are reasons to replace earlier. Hot cars, dishwashers, and direct sunlight all degrade the material faster. Our care and replacement page covers cleaning routines and storage.
Payment
Health funds and payment
Sandgate Family Dental is a HICAPS provider. Where your private health fund includes mouthguard rebates, we process the claim at the practice and you only pay the gap. The rebate depends on your individual policy and annual limits — your fund can confirm before the appointment.
FAQs
Combat sports mouthguard FAQs
Do I need a different guard for boxing vs BJJ?
Not necessarily, but the priorities differ. Boxers want a guard that absorbs direct strikes and stays in place when the mouth is open. Grapplers need a guard that does not dislodge during clinches and ground exchanges. We talk through your main discipline at the scan appointment so the lab can build accordingly.
Can a custom mouthguard prevent a broken jaw?
A mouthguard can absorb some of the force that would otherwise travel through the jaw, but it cannot prevent every injury. We do not make absolute claims — guards can reduce the risk of dental and soft-tissue injury, and that is what they are designed for.
How thick should a combat sports guard be?
Most combat guards are made thicker than field-sport guards, particularly over the front teeth. The lab will spec the thickness to suit your discipline, your bite, and your preferences. Too thick can affect breathing — we balance protection and airflow.
Does a mouthguard prevent concussion?
Current evidence does not support claims that mouthguards prevent concussion. They are designed to reduce the risk of dental and soft-tissue injuries. Follow your discipline’s medical protocols for head injuries.
Can I get a guard with my fight name on it?
Most labs offer custom colours, two-tone combinations, and lettering. You can choose at the scan appointment.
I clench a lot when I roll — am I damaging my teeth?
Heavy clenching can cause wear, sensitivity, or cracks over time. A custom guard cushions the bite. If you also clench or grind at night, you may benefit from a separate nightguard — they are designed differently. See nightguard vs sports mouthguard.
How quickly can a replacement be made if mine breaks before a fight?
If your scan is on file, a replacement can usually be turned around in one to two weeks. Phone us and let us know the timing.
