Top features to consider


Like many other contact sports, rugby requires minimal equipment to keep the players safe from possible injuries. But since the offer is generous, there’s always the question what is the best mouth guard for rugby? Some features that should be on your list are mentioned in the following paragraphs.



Impact response


Since the main reason you should be wearing the mouth guard is to keep you safe from powerful strikes or accidental hits, you must ask yourself how much protection you receive.

The material used in the construction must be capable of withstanding tough impact. But it’s also important that the gel or plastic cushions your teeth and gums. If the force of the hit is dispersed or absorbed, your jaw should be fine and your teeth unshaken.

The shape and snug fit of this protective equipment is just as important as they can prevent unfortunate accidents and weaken the impact on the bone structure or dentition.





The quality of the material has to be doubled by the thickness of your mouthguard. It’s only natural that thinner gear will put up less successfully with damaging strikes.

Keep in mind, though, not to pick the items that show impressive size, because the thicker and bigger they get, the harder it will be for you to deal with them while you’re fast moving on the field or talk to your team mates.



Comfortable wear


Mouth guards that provide the best fit and are great for wearing them all through the game should be comfortable enough to allow regular, unobstructed breathing and some degree of verbal communication.

If you’re using a mouth guard that you molded yourself, it should be fit on your dentition. If it falls out during the game, it’s not the best rugby mouth guard. It’s recommendable to own a gear piece that molds to your teeth without bloating your lips.





There’s one type of mouth guard that you can find for sale at reasonable prices, the so called boil and bite. Made of thermoplastic, it is cheap enough to change it from time to time, and it allows you to make your own mold.

Custom mouth guards are more expensive and require the assistance of a dental technician. The best mouth guard for rugby reviews will probably point to such an investment, but if you’re a beginner and don’t intend to take this to the next level, then perhaps it’s better to stick to cheaper ones for a while.
