Why do rugby players need a mouthguard?

Rugby is a high-contact sport with a significant risk of dental injury — collisions, tackles, rucks, and physical contact with other players, the ground, or the ball all create impact forces that can fracture, knock out, or damage teeth and soft tissue. A well-fitted mouthguard absorbs and distributes these impact forces, dramatically reducing the risk of dental injury.
Dental trauma is one of the most common injuries in contact sports, and the cost of replacing or repairing damaged teeth — which can run into thousands of pounds — far exceeds the cost of any mouthguard.
Beyond tooth protection, mouthguards also protect the lips, cheeks, and tongue from laceration, reduce the risk of jaw fractures, and may help reduce the severity of concussive impacts by preventing the lower jaw from slamming into the upper. Wearing a mouthguard in rugby is mandatory in many competitions and is strongly encouraged at all levels.

A boil-and-bite mouthguard is the most practical and widely used form of rugby mouth protection. The process is straightforward: the guard is softened briefly in boiling water until pliable, then placed in the mouth and bitten down on firmly, with the lips and cheeks pressed in around it to create an accurate mould of your teeth and gums.
As it cools, it sets to the shape of your dentition — giving a personalised fit that is far superior to a generic stock guard. Boil-and-bite mouthguards are affordable, immediately available, simple to fit at home, and suitable for players at all levels of the game. Mouthguards Direct specialises in high-quality boil-and-bite mouthguards for rugby, supplying both individual players and teams across the UK.

Junior rugby players should wear a mouthguard from the moment they begin playing contact rugby — typically from age seven or eight in mini rugby, depending on the format. Children’s dental development makes this especially important: baby teeth are being replaced by permanent adult teeth during this period, and damage to adult teeth at a young age has lifelong consequences.
Junior mouthguards must be sized appropriately for a child’s smaller jaw and need replacing more regularly than adult guards as the dentition changes — a guard that no longer fits correctly due to new teeth erupting will not provide adequate protection. Mouthguards Direct stocks junior boil-and-bite mouthguards sized specifically for younger players, and we recommend re-fitting or replacing the guard at least annually as their teeth change.

No — the colour and design of a mouthguard have no effect on its protective performance; these are purely aesthetic choices. Boil-and-bite mouthguards are available in a wide range of colours and styles, making it easy for players to match team colours or choose a personal look. This makes them popular for club and school teams who want a consistent appearance, and helps individual players identify their own guard in a kit bag.
The protective properties of any mouthguard are determined entirely by the quality of the material, its thickness in the critical protection zones, and how well it has been fitted — none of which is affected by colour. Mouthguards Direct offers a broad range of colours and designs, and can accommodate team orders for clubs and schools.

Research into mouthguard protection in contact sports indicates that a minimum of 3–4mm of material in the occlusal (biting) zone is necessary for effective energy absorption. A quality boil-and-bite mouthguard, correctly fitted, achieves good coverage across the upper teeth and gums.
The key to getting adequate thickness from a boil-and-bite guard is following the fitting instructions carefully: softening the guard for the right amount of time (not too long, which thins the material), biting firmly and evenly, and using your fingers and tongue to press the material snugly around the teeth and into the gumline. A poorly fitted boil-and-bite that has been bitten through unevenly will have thin spots that compromise protection — which is why using a high-quality product from Mouthguards Direct and following the fitting guide makes a real difference to the level of protection you achieve.

Getting the best fit from a boil-and-bite mouthguard comes down to following the process carefully. Start by boiling water and allowing it to cool for 30–45 seconds — the water should be very hot but just off the boil, around 70–80°C. Submerge the mouthguard for the time specified in the instructions (usually 20–30 seconds) until it turns clear and pliable. Remove it carefully, shake off excess water, and centre it over your upper teeth immediately. Bite down firmly, then use your fingers to press the guard firmly against the outside of your teeth and cheeks, and use your tongue to push up against the inside. Hold this for 30–45 seconds before removing and placing in cold water to set.
The result should be a guard that sits snugly, stays in place without clenching, and covers all upper teeth. If the fit is not satisfactory, many boil-and-bite guards can be re-softened and refitted once. Mouthguards Direct includes full fitting instructions with every product.

Maintaining your mouthguard correctly extends its life and prevents bacterial build-up. After each use, rinse the guard under cold water immediately — never use hot water, which can distort the shape. Clean it regularly with a soft toothbrush and mild soap or a non-abrasive toothpaste; dedicated mouthguard cleaning tablets are also effective and convenient.
Allow the guard to air dry before storing it in its protective case — storing it damp encourages bacterial growth. Keep the case clean too. Keep the guard away from heat sources: the dashboard of a car on a sunny day, near radiators, or in a kitbag left in direct sun are all risks that can warp the material. Replace your mouthguard if you notice it has become distorted, cracked, or if it no longer fits snugly — a poorly fitting guard does not provide adequate protection.

This is an important question for any player currently in orthodontic treatment. Players with fixed braces face a higher risk of soft tissue injury, as the brackets and wires can cause significant lacerations to the lips and cheeks during impact if not protected. Standard boil-and-bite mouthguards cannot be fitted over fixed braces in the normal way — the heat and pressure of the fitting process can damage the brackets or the archwire.

Standard boil-and-bite mouthguards cannot be fitted over fixed braces in the normal way — the heat and pressure of the fitting process can damage the brackets or the archwire.
For players with braces, a brace-compatible or orthodontic boil-and-bite mouthguard is available: these are made from a softer, more flexible material that accommodates the brackets without requiring the standard fitting process, and sits over the braces to protect both the soft tissue and the orthodontic appliance. Mouthguards Direct recommends any players with braces or orthodontic work speak directly to their dentist or orthodonist prior to ordering any mouthguards.

Even a well-made boil-and-bite mouthguard does not last indefinitely and should be replaced regularly. For adult players, a mouthguard used throughout a season typically warrants replacement at the start of each new season — or sooner if signs of wear appear. Signs that a guard should be replaced include: visible distortion or change in shape; cracks or holes in the material; loss of fit (the guard no longer sits snugly without clenching); or if it has absorbed a particularly heavy impact that may have compressed or compromised the material.
Because boil-and-bite guards are very affordable, there is rarely a reason to persevere with a guard that is past its best — a fresh, well-fitted guard always provides better protection. For junior players, whose teeth are actively changing, checking the fit regularly and replacing when new teeth have altered the fit is especially important.
