After a gi, a gumshield is probably the most important purchase for anyone who does a lot of BJJ. Boil in the bag mouthgards are rubbish. Even the expensive ones don’t fit that well and just get in the way.
You might think that you can get away with training without using a gumshield because you’re not getting punched in the face, but accidental kicks and knees are a hazard of the sport and after ten years of grinding your teeth together during headlocks they will get worn down and damaged. The rest of your body will heal up, but your teeth won’t.
Gumz.co.uk do a line of custom gum shields, and are offering a £5 discount with the code FBCOM. The cheapest variant is £15 after the discount. That’s for a gum shield with the Gumz branding. You can get clear gumshields or single colour ones for a little more, or spend extra for custom designs.
It’s a good idea to get a new custom gumshield made every couple of years because your teeth move around naturally. You may not notice it at first, but when you get a new custom fit one you will be able to feel the difference.
