Choosing the right mouthguard is not a minor detail. In boxing, kickboxing, Muay Thai, and MMA, this protection comes into play whenever there is contact: during sparring, intense training sessions, and, of course, in competition.
A good mouthguard must protect, remain stable, allow for proper breathing, and be tolerable even when the pace picks up. It's not enough for it to just "stay in your mouth": it must fit the dental arch well, not force continuous biting, and not cause discomfort during technical work or combat.
In this guide, we will see how to choose the most suitable mouthguard for your level, your discipline, and how often you train.
Why it's essential to use a mouthguard in combat sports
The mouthguard is a fundamental protection in combat sports because it helps to absorb and distribute part of the impact when blows to the face, close contacts, or sudden pressures on the jaw occur. Its role is not to "make you invulnerable," but to help reduce the risk of dental trauma, lip and gum injuries, and stress on the mouth during activity.
In boxing, kickboxing, Muay Thai, and MMA, the mouthguard is not only useful in competition. Even in the gym, during sparring, partner drills, or high-intensity sessions, it can make a big difference in terms of safety and confidence. Those who train know that when the mouthguard is comfortable and stable, you can better focus on technical execution, guard, distance, and the work required by the coach.
This is why it's important to understand how a mouthguard works: protection depends on several elements combined, such as material, thickness, fit, and ability to stay in place even when breathing with an open mouth or talking between rounds. In a complete training bag, the mouthguard is not a secondary accessory, but part of the technical equipment. Using it regularly means training with greater awareness, choosing protection consistent with the real contact of your discipline.
Types of mouthguards available
There are three main types of mouthguards, differing in terms of protection, comfort, and adaptability.
- Pre-formed mouthguards are ready to use and not customizable: they can be immediate, but tend to offer less stability and comfort, especially during intense training.
- Boil-and-bite mouthguards, or thermoformable ones, are heated and molded to the dental arch. This is often a balanced solution for those who train regularly, provided the molding is done correctly.
- Custom-made mouthguards are created by a dental professional from an impression of the athlete's dental arch. They offer the highest level of personalization, retention, and comfort, with higher costs and lead times. They are particularly suitable for those who engage in intense sparring, train frequently, or compete.
How to choose the right mouthguard: features to evaluate
To choose a good boxing mouthguard, kickboxing mouthguard, Muay Thai mouthguard, or MMA mouthguard, you need to look beyond aesthetics and price. The first criterion is fit: the mouthguard must remain stable without forcing you to constantly clench your jaw. If it moves, falls out, or bothers you as soon as you start breathing more intensely, it's probably not suitable or hasn't been molded correctly.
The second element is the material. The most common material is EVA, used because it combines elasticity, absorption, and comfort. More advanced models may feature multi-layered structures or different materials, but a complex design should not be confused with an automatic guarantee of greater protection: what matters is the real result in terms of fit, stability, and effective thickness.
Thickness should also be carefully evaluated. A mouthguard that is too thin may be discreet, but does not always offer adequate protection; one that is too bulky can interfere with breathing, speaking, and tolerability during sparring. The sweet spot is a balance between protection, low bulk, and comfort.
Finally, consider durability and maintenance. A mouthguard should be replaced when it loses shape, adhesion, or integrity, or if it shows cuts, deformities, or obvious signs of wear. For those who train often, checking it regularly is a good habit.
The discipline affects the choice. In boxing, fit precision and comfort between rounds matter; in kickboxing, stability is needed even when the pace picks up; in Muay Thai, retention is important in the clinch; in MMA, the mouthguard must stay put even during transitions. The best choice, therefore, is not the "most famous" model, but the one most consistent with training, sparring, and goals.
Buying guide: which mouthguard to choose
Choosing the right mouthguard depends on three simple questions: what discipline do you practice, how often do you train, and with what intensity? Beginners have different needs than those who spar regularly or prepare for a competition. Similarly, an MMA or Muay Thai mouthguard must respond to more dynamic situations than light use in the gym. In the following paragraphs, we will see which mouthguard to choose based on level, training frequency, and specific needs, including the choice of protection for younger athletes. This way, the purchase becomes more informed and less dependent on improvisation.
Which mouthguard to choose if you are a beginner
If you are a beginner, look for a mouthguard that is easy to use, comfortable, and sufficiently stable. The goal is to gradually get used to the protection without experiencing the mouthguard as an obstacle during training.
For basic technique, pad work, and light sparring, a good boil-and-bite model can be a balanced choice, especially if molded carefully. Avoid overly basic solutions that move easily or require you to bite to stay in place: at first, it's important to feel protected, but also to be able to breathe and concentrate on the fundamentals.

Which mouthguard to choose if you train more intensely
If you train several times a week, engage in medium or intense sparring, or practice disciplines with close contact such as Muay Thai and MMA, the choice must be more careful. In these cases, retention, material quality, stability, and comfort during prolonged use become essential.
A kickboxing mouthguard, boxing mouthguard, or Muay Thai mouthguard intended for intense training must stay in place even when fatigue increases. In MMA, where striking, grappling, takedowns, and ground phases can alternate quickly, stability is even more important.
If you compete or spar hard regularly, a custom-made mouthguard remains the most rigorous option. Alternatively, a good quality boil-and-bite can be an interim solution, provided it is truly stable and well-molded.

Where to find mouthguards and protection for children
For younger athletes, the choice of mouthguard must be even more careful. A children's mouthguard must be age-appropriate, comfortable to wear, and consistent with the type of activity performed. It should not be excessively bulky, but it must offer adequate protection for training, technical exercises, and initial controlled contact experiences.
For children and adolescents, growth, changes in the dental arch, and the possible presence of orthodontic appliances must also be considered. If there are doubts about the fit or the dental situation, it is always best to consult a professional.

How to properly mold a boil-and-bite mouthguard
Knowing how to mold a mouthguard is essential, because poorly executed molding can compromise fit, comfort, and protection. Each model may have specific instructions, so the first rule is to always follow the product's guidelines.
In general, a boil-and-bite mouthguard is heated in hot water to soften the material, then inserted into the mouth and adapted to the dental arch using controlled pressure from teeth, lips, and fingers. After the molding phase, it is cooled to stabilize the obtained shape. The point is not just to "take an impression," but to achieve a functional seal.
A properly molded mouthguard should remain stable, not fall out as soon as you open your mouth, not require continuous clenching, and allow for manageable breathing. You should also be able to utter a few short phrases, as might happen between rounds or during coach instructions.
If, after molding, the mouthguard moves, creates pressure points, causes nausea, or interferes too much with breathing, it may not have been adapted correctly or may not be the right model for your dental arch. In these cases, it is better to refit it, if the product allows, or replace it.
One final tip concerns maintenance after each use. Rinse the mouthguard before and after training, clean it regularly with gentle products, let it dry, and store it in a rigid, ventilated container. Avoid excessively hot water or heat sources, as they could deform the material and reduce the quality of the fit. If the mouthguard loses adhesion, thins, or shows obvious cuts, it's time to replace it.
FAQ
Is a mouthguard mandatory in combat sports?
It depends on the discipline, regulations, and the context in which one trains or competes. In many cases, a mouthguard is required during sparring and competitions, but even when it is not formally mandatory, it remains a strongly recommended protection. Using it regularly helps to reduce the risk of dental trauma and to better protect the mouth and jaw.
Does a mouthguard affect breathing or speech?
A mouthguard can alter the sensation in the mouth, especially during the first uses or if it is not chosen well. However, a well-fitting and correctly molded model tends to be more stable, more comfortable, and less intrusive even during intense training. The fit matters more than any stated feature: if it stays put and doesn't require continuous clenching, breathing and communication are more manageable.
How long does a mouthguard last?
The lifespan depends on frequency of use, intensity of training, material quality, and maintenance. In general, a mouthguard should be replaced when it loses shape, adhesion, or integrity, or when it shows cuts, deformities, or obvious signs of wear. For children and adolescents, growth and any changes in the dental arch must also be considered.
What is the most suitable mouthguard for beginners?
For beginners, it is important to choose a mouthguard that is easy to use, comfortable, and has a good fit. The goal is to find a model that offers adequate protection without being too uncomfortable, so that you can gradually get used to using it during training and light sparring. A good boil-and-bite can be a balanced choice for many beginners.
What is the difference between a pre-formed, boil-and-bite, and custom-made mouthguard?
A pre-formed mouthguard is ready to use but less customizable. A boil-and-bite one adapts to the mouth after molding and often represents a good compromise between comfort, protection, and practicality. A custom-made mouthguard offers the highest level of adaptation, stability, and comfort, but requires a dedicated process and higher costs.
