Wrestling, Grappling and Sambo Mouthguards

Quick answer: in wrestling, grappling and sambo, the teeth do not take punches but head, knee or shoulder impacts in close-quarters work, often unpredictable ones. The right mouthguard has a low profile, lets you breathe through your mouth when you are flattened on the mat and stays in place when the jaw is pushed. A boil-and-bite model is fine for starting out; a custom-fit model is better for competitors and for combat sambo, where strikes are added to the throws.

Impacts without strikes, but very real ones

In grappling sports, dental injuries rarely come from a deliberate blow. They happen during a clash of heads on a leg shot, a knee coming up during a guard pass, a shoulder to the chin on a throw or a fall to the mat. These impacts arrive without a guard up or any warning, which makes them all the more dangerous for the incisors and lips.

The mouthguard, or gum shield, separates the two arches, cushions the sudden closing of the jaw and protects the soft tissues from the teeth. It also limits injuries to the tongue and cheeks in a tight scramble.

Olympic wrestling, grappling and sambo: similar needs

Freestyle and Greco-Roman wrestling are practised standing and on the mat, with constant head-to-head contact. Grappling, with or without the gi, extends the fight on the ground with submissions, where the head is often controlled or crushed. Sport sambo resembles wrestling with leg locks; combat sambo adds strikes, and the mouthguard is then required just as it is in the other striking disciplines.

In France these three families come under the French Wrestling Federation, whose rules specify the protective equipment allowed or required for each discipline and category. In every case, the common criterion remains the same: a slim, stable model that lets you breathe. The BJJ guide looks in more depth at Brazilian jiu-jitsu.

Breathing with an opponent on your chest

On the mat, your cardio depends on being able to breathe under pressure, often with your mouth open, while an opponent crushes your ribcage or face. A mouthguard that is thick or extends too far back triggers the gag reflex and forces you to spit it out, which exposes your teeth at the worst possible moment. Look for a low profile, short at the back and clear of the palate.

It must hold on the upper arch without you clenching your teeth: if you have to bite down constantly to keep it in, you lose air and tire your jaw. Test the guard under pressure on the mat, not just standing up.

Boil-and-bite or custom-fit, depending on your level

To discover wrestling or grappling, a carefully moulded boil-and-bite mouthguard (thermoformable, moulded at home in hot water) is enough. Mould it according to the instructions, let it cool and check that it stays in with your mouth open. Do not trim it yourself beyond what the manufacturer allows: you would weaken its structure.

For several sessions a week, competition or combat sambo, a custom-fit mouthguard made from a dental impression offers a slimmer profile and a hold that does not depend on your bite. At Proteksports, generally allow 5–10 days after your impression has been approved. If your training mixes groundwork and strikes, the MMA guide details the trade-offs between the two.

Rules, competition and young wrestlers

Requirements vary by discipline, federation, age category and organiser: recommended in Olympic wrestling, often required in grappling and compulsory in combat sambo. Read the current version of the rules and show your guard to your coach before the event. On inspection day, it must be clean, in good condition and properly fitted.

Wrestling is taught from a very young age in clubs. In children, check regularly that the mouthguard is not squeezing an erupting tooth and replace it as soon as growth makes it unstable. With orthodontic braces, ask the orthodontist for advice before choosing.

Fit, care and ordering

The steps common to all sports are in the instructions and the comparison.

In wrestling, grappling or sambo, test the model under pressure on the mat before approving it for competition.
