Best Gumshields for Contact Sports

What Is a Gumshield?

A gumshield (or mouthguard) is a protective device worn over the upper teeth to absorb and distribute impact forces during contact sports. It protects your teeth from chips and fractures, cushions blows to the jaw, and research suggests it may reduce the severity of concussions by absorbing shock transmitted through the jaw.

A knocked-out tooth costs £1,000+ to fix. A gumshield costs a few quid. The maths is simple.

Who Needs One?

Anyone playing contact sports: rugby, boxing, MMA, hockey, lacrosse, basketball, and even football if you play competitively. In rugby union and league, gumshields are mandatory at all levels. In boxing and MMA, you won’t be allowed to spar without one.

Even in training, a stray elbow or accidental head clash can happen. Wearing a gumshield should be as automatic as tying your boots.

What to Look For

Type is the key decision. Stock gumshields are pre-formed and ready to wear — they’re cheap but don’t fit well and offer the least protection. Boil-and-bite gumshields soften in hot water so you can mould them to your teeth at home — they’re the most popular option and offer decent protection. Custom-moulded gumshields are made by a dentist from an impression of your teeth — they fit perfectly, stay in place, and offer the best protection and comfort.

Fit determines whether you’ll actually wear it. A gumshield that gags you, falls out when you breathe, or restricts talking too much will end up in your bag instead of your mouth. Custom-moulded shields fit so well you barely notice them.

Thickness affects protection and comfort. Thicker guards absorb more force but feel bulkier in the mouth. Most quality boil-and-bite shields are 3-4mm thick. Custom shields can be thinner while still offering superior protection because the fit is so precise.

Breathing channels or holes in some designs help with airflow. This is important for high-intensity sports where mouth breathing is constant.

Material is usually EVA (ethylene-vinyl acetate). Higher-quality guards use multi-layer construction with a harder outer shell and softer inner layer for comfort and protection.
