How Should A Mouthguard Fit?

Regardless of what your mouthguard is for, a mouth guard should always fit properly. If you have already felt unsafe and uncomfortable wearing a mouth guard that didn't fit well, here are 2 easy ways to identify a safe mouthpiece.

Should a mouthguard fit tightly?

If you wear a standard or slim fit mouth guard, the first thing you should notice about the fit of your guard is that it snaps into place and fits very snugly. You shouldn't need to close your mouth to keep you guard in place and if it doesn't fit like a glove, something is wrong.

However, if your guard feels like it’s putting so much pressure on your teeth that it’s moving them, that's a sign that the guard is badly molded or too small and should be changed.

If you have a Nxtrnd Mouthguard, we recommend you follow our simple 10 step fitting guide included in every package to get the perfect fit.

Should a mouthguard be comfortable? 

A mouth guard should always fit comfortably. In fact, a good mouth guard will let you speak and breath very easilyAn important aspect about the fit of your mouth guard is that it won’t be molded to your teeth all the way to the upper gum line and won't extend all the way to your back molars.

Thin Mouthguard

When a mouth guard is too high, it will rub against your gums and lips creating discomfort and irritation which can end up being a distraction during a game. Also, a mouth guard that extends to far back will come in contact with the wearers soft tissue and cause a gag reflex.

Ideally, a comfortable mouth guard will cover all your teeth (with exception of the first or second back molars) and some of your gum line without overwhelming the entire jaw.

For a mouth guard designed to offer the correct amount of coverage, we recommend looking into the Nxtrnd Rush, the Nxtrnd Classic or the Nxtrnd Zero which have become Amazon's top rated mouthguards in the contact sports and outdoor sports categories.
