Great
This is way too big, it hurts my jaw!
Does what it says on the tin, great value, moulds nicely after heat
Great product as always from this store.
the fit was totally wrong after shrinking the guard with hot water. not possible to fit teeth into the groove and was very uncomfortable. I think you need to improve on the design of the guard.

It does the job but if your going to use it on a regular basis or for long periods of time I’d recommend investing in a proper dentist fit gum shield! It’s fine if your on the mats at a karate / kick boxing comp or club sparring but if your getting in the ring or play rugby it’s no good as it loosens off as it warms up in your mouth and starts to drop!

Incredible wow just amazing I can believe it
I buy these in bulk because my son and the other U15s chew their way through them. Unless you are getting one made by an orthodontist just buy one of these
We are happy that you like our product. Your feedback is very important for us.I hope your son will enjoy

I bought a mouthguard for the second time at decathlon because the first one i thought i had messed up as the product would not stay on the upper tooths and was way too big for the under teeth. So i bought it for the second time to see if it would make a difference if i would exactly follow the instructions, same result! What a waste of my money , TWICE! How can you sell a product that does not do its work, even with the instruction video you can see that the product is way to big. Really dissapointed !
Thanks a lot to send us your opinion on 100 Adult Mouthguard. I'm sorry to hear all your trouble to fit the mouth-guard. Your kind of feedback are very useful for our product managers in order to design and produce better products.
Don t forget you can claim a total refund or a product change in one of our Decathlon store
Kind regards

Works well so very happy
For the very cheap price I thought I'd try one of these for a laugh after deciding to do a bit of sparring after a long absence. Following the application instructions to the letter I'm left with at least 6mm extra plastic at the bottom below my teeth, hence not fitting at all and falling out. You can see for yourselves how very badly this mouthguard fits the model in the Decathlon video on this page, he's got more mouthguard below his teeth than actually on them, mine is exactly the same. I wouldn't waste time returning but it shall be going in the bin & I'm off to the dentists to get a proper one, that actually fits. Waste of time and money.
Thanks for let us know your opinion on 100 Adult Mouthguard. This kind of very detailed feedback are really important for us in order to develop better products that can meet your expectations and be useful to practice boxing. I ll pass it to our R&D department.
Thanks again and sorry for any problems caused by the item
Kind regards

Excellent, good value for money.
Used by our son, 12 years old, for PE lessons at school. Relatively straight forward instructions to follow to mould to teeth.
Have tried various mouthguards for my 13 year old and this is the best he has tried

Who is it designed for?
We designed an ergonomic mouthguard made of 100% EVA for easier molding and optimal support. The adult mouthguard that fits everyone.
How do you choose a mouthguard?
Other than the different sizes, there are 2 types of mouthguards: - Single mouthguards protecting the upper half of your mouth. They make breathing easier. This is this type of mouthguard used for playing rugby. - Double mouthguard covering all of your teeth. This type is larger and not suitable for rugby. They are generally found in combat sports such as boxing and martial arts.
Which size?
Our range currently includes 2 sizes: - Child size: for children under 12, - Adult size: for adults or children over 12. Of course, you need to adapt to suit your child's size as they grow. Certain children can use an adult size before age 12, while others need to wait longer before moving up in size.
A few tips for use.
We recommend always wearing a mouthguard during training and matches. To get the shape right when you mold it, soak it in boiling water for exactly the right amount of time. This time will be indicated in the user guide. It can vary from model to model. Watch the video tutorial to find out how to mold your mouthguard. To guarantee good protection, your mouthguard should stay in place when you open your mouth.
A few care tips.
You can wash your mouthguard in fresh water after each use. Before putting it in its case (original box), let it dry for a while. If you use it regularly (1 match, 1 training per week), we recommend replacing your mouthguard each year in order to preserve its protective performance. It begins to show signs of wear, do not hesitate to replace it.
