How to choose the right boxing mouthguard

A boxing mouthguard is a protective device for the teeth and the temporomandibular joint, used during training sessions and sparring. This protection reduces the risk of enamel chips, cracks, dislocations, and cuts to the oral mucosa. Even with light contact, the load on the teeth remains high. The guard absorbs part of the impact, distributes pressure, and creates a cushioning layer between the teeth and soft tissues. A properly fitted model does not interfere with breathing, does not trigger a gag reflex, and keeps its shape during regular use.

What is a mouthguard used for?

With a direct hit, the jaw receives a sharp load: the teeth clamp together with force, and the impulse is transferred to the joint and bone. Without protection, the pressure concentrates in one area, increasing the risk of tooth fractures and ligament damage. A boxing mouthguard distributes the impact across the entire arch, partially absorbs the energy, and keeps the jaw in a stable position.

The material works as a buffer between the teeth and the lips. This reduces the number of bites, lowers the risk of cuts, and protects the roots from microcracks. During contact, the guard also stabilizes the tongue, which reduces the likelihood of injury. That is why boxing mouthguards are essential for beginners.

Types of boxing mouthguards

There are two main types available on the market:

1. Single‑jaw model — covers the upper row of teeth. It is lighter, does not restrict lower jaw movement, and is suitable for beginners.
2. Double‑jaw version — fixes both rows. This design stabilizes the joint more effectively but partially restricts breathing.

By manufacturing method, products are divided into three categories: standard pre‑formed guards, thermoplastic boil‑and‑bite models, and custom guards made from a dental impression. A ready‑made model is cheaper but fits the anatomy less precisely. A custom dental version is the most accurate but costs more. Thermoplastic options are considered optimal in terms of price and protection.

Choosing the right mouthguard size for boxing

Size is selected based on age and jaw structure. Manufacturers offer both junior and adult versions. A kids’ boxing mouthguard is shorter and narrower and is designed for primary and mixed dentition. An adult guard will not fit properly in a child’s jaw and may shift during impact.

A properly sized guard should stay in place without constant biting. There should be no pressure on the palate or gums. If the guard slips, presses, or prevents you from closing your mouth, the size is incorrect.

How should you fit a boxing mouthguard?

Thermoplastic models must be molded to your bite before use. Basic steps:

1. Place the guard in hot water according to the instructions.
2. Remove it with tongs and let the surface cool slightly.
3. Put it on the upper teeth and close your jaws.
4. Press the material against the teeth and gums with your fingers.
5. Hold for 5–10 seconds and then cool it in cold water.

After molding, the guard should not fall out when talking or inhaling and should remain stable when opening your mouth. Reheating is allowed once. Frequent remolding damages the material.

How to wear a mouthguard correctly?

Wear protection during all exercises with a risk of head impact: sparring, partner drills, and contact training. Skipping the guard even for one session increases the risk of injury.

After training, rinse the guard with warm water, clean it with a soft brush if necessary, and let it dry. Store it in a ventilated case. Overheating deforms the material. If cracks or deep dents appear, replace the guard.

How much does a boxing mouthguard cost?

The price depends on material density, thickness, and brand. Simple standard options are cheaper but lose their shape faster. Thermoplastic guards last longer and adapt more precisely to the bite. Custom dental guards are the most expensive.

If you train regularly, it is more practical to buy a boxing mouthguard with a fitting option. Such protection lasts longer and ensures a stable fit. A mid‑range model is optimal for beginners.
