Safejawz Nitro series mouthguards offer a super slim easy fit whilst still offering elite level protection!

Gum shields can be difficult to fit, however, Remodel Tech™ facilitates multiple fitting attempts so that you can always achieve a perfect fit. Remodel Tech™ is a trademark exclusive to SAFEJAWZ.

Fluid Fit™ technology will ensure that the guard follows the contours of the teeth which will result in superior impact absorption and real comfort.

Jaw Secure™ offers a pre-contoured base which can assist with stabilising the jaw and protecting the bottom set of teeth also. A sports mouthguard should protect more than just the teeth.

Antimicrobial Biomaster Silver Biocide, protects the surfaces from bacterial growth for the life of the mouthguard, keeping it fresh and hygienic.

Safejawz handy fitting guide can be viewed here to help you achieve a perfect fit.
