Mouthguards: The Smartest Defence for Your Smile

No dental technology — however advanced — can fully replicate what nature built. A knocked-out tooth, a fractured jaw, or a lacerated lip sustained during sport can have consequences that linger for years, requiring multiple treatments and significant ongoing cost. A well-fitted mouthguard is one of the most cost-effective pieces of protective equipment an athlete can own, guarding not just teeth but also the tongue, lips, cheeks, and jaw against the unpredictable forces of contact sport.

Why Dental Injuries Happen in Sport

The most common triggers for sport-related oral injuries include collisions with other players, contact with equipment such as balls, bats, sticks or racquets, falls, and accidental impacts. A mouthguard is purpose-built to absorb and redistribute the energy from these kinds of impacts — reducing the force that reaches the teeth and surrounding structures before real damage can occur. The protective value of mouthguards is well established and backed by substantial research across a range of contact sports.

A Century of Protection

Mouthguards are not a modern invention. Professional boxers have used them since at least the 1920s, and over a century of use across sport has only reinforced their effectiveness. In many disciplines today, wearing a mouthguard is not optional — it is a mandatory rule. Their track record of lowering both the frequency and severity of oral injuries is thoroughly documented.

Custom-Fitted Mouthguards Outperform Everything Else

For players involved in body contact and collision sports, a mouthguard is not a luxury item — it is essential protective equipment. According to the Australian Dental Association, more than two percent of Australian children sustain a dental injury each year, and contact sports are among the leading contributors. The difference between a generic mouthguard and one professionally fitted by a dentist is significant — in terms of comfort, retention, and the actual level of protection delivered.

How a Mouthguard Works

At its core, a mouthguard functions as a shock absorber. It sits between the upper and lower dental arches, cushioning direct blows and spreading impact energy across a wider surface area rather than concentrating it on individual teeth. This cushioning effect directly reduces the likelihood of fractures, avulsions (knocked-out teeth), and lacerations to the soft tissues of the mouth. A properly fabricated mouthguard protects:

Lips | Teeth | Jaw | Gums

Your First Line of Defence Against Orofacial Injury

Research cited by the ADA suggests that athletes who do not wear a mouthguard face an oral injury risk approximately 60 times higher than those who do. Beyond direct tooth protection, mouthguards also help prevent the kind of soft tissue damage — split lips, tongue lacerations, cheek cuts — that occurs when a blow forces the mouth closed suddenly. Not all mouthguards deliver this level of protection equally, however. The type you choose matters considerably.

The Three Types of Mouthguards Compared

There are three distinct categories of mouthguards, and they differ substantially in fit, comfort, and protective capability:

  • Dentist-fitted (custom-made) mouthguards
  • Self-fitted (boil and bite) mouthguards
  • Over-the-counter (stock) mouthguards

Custom-Made Mouthguards

A custom-made mouthguard is fabricated specifically for your mouth — built from impressions of your actual teeth and produced using professional dental equipment. The material is chosen for its shock-absorbing properties, and the result fits more precisely and comfortably than either of the alternatives. Breathing, speaking, and swallowing are all easier with a well-fitted custom mouthguard, which means athletes are more likely to keep it in rather than remove it during play.
At Dental Nook, custom mouthguards are manufactured using a heat-vacuum process over dental casts taken directly from impressions of your teeth — ensuring the fit is as accurate as possible. This is the gold standard of mouthguard protection.

Boil and Bite Mouthguards

The boil and bite variety uses a thermoplastic material that is softened in hot water and then moulded to the mouth by biting into it. While these are more affordable than custom options and widely available, the fit they produce is considerably less precise. The moulding process is difficult to replicate accurately at home, the material tends to distort over time, and the level of protection they offer falls well short of a custom-fitted appliance.

Stock (Over-the-Counter) Mouthguards

Stock mouthguards are the simplest option — pre-formed, available off the shelf, and requiring no preparation. They are also the least effective. Because they come in limited sizes and are not shaped to any individual’s teeth, they typically sit loosely in the mouth and must be held in place by clenching the teeth together. Stock mouthguards made from rigid plastic are particularly poor at dissipating impact forces — which is the entire point of wearing one. Many dental professionals advise against relying on stock mouthguards for genuine protection, as they can create a misleading sense of security without delivering it

Ready-Made Mouthguards

Stock mouthguards are also referred to as ready-made, over-the-counter, or off-the-shelf mouthguards — all referring to the same pre-formed category.

What Makes a Quality Mouthguard

A high-quality, dentist-fitted mouthguard sits comfortably and snugly without restricting breathing or making conversation difficult. It moves with the mouth naturally rather than requiring constant repositioning. Beyond tooth protection, it acts as a barrier that prevents lips and tongue from being caught against teeth during an impact. Quality mouthguards are also straightforward to keep clean with regular gentle brushing.

Mouthguards for Children

Boys aged eight to twelve years have the highest rate of dental injuries among children — making this an age group where a properly fitted mouthguard is particularly valuable. Custom-made mouthguards are the recommended choice for children precisely because the fit is accurate and consistent, allowing kids to play comfortably without the distraction of a loose or ill-fitting appliance.
An added practical benefit for younger players: custom mouthguards can be made in a range of colours, making it far easier to identify a child’s own mouthguard in a bag or on the sideline — and harder to lose on the grass. When kids find a mouthguard comfortable and easy to wear, they are significantly more likely to actually wear it.

Sports Mouthguards

Every time an athlete takes to the field in a contact sport, they accept a measurable risk of oral injury. Some research estimates the per-session risk of an oral injury at around ten percent, rising to as high as fifty percent across an athlete’s career. A custom-fitted mouthguard substantially lowers that risk.
Sports where mouthguard use is strongly recommended include: Soccer, Football, Rugby, AFL, Wrestling, Basketball, Baseball, Water polo, Hockey, Netball, Volleyball, Kickboxing, and all forms of Martial arts. In sports where mouthguards are compulsory, the rate of oral injuries has dropped markedly — a direct reflection of their effectiveness in absorbing and redistributing impact forces that would otherwise cause fractures, chips, avulsions, and soft tissue lacerations.
Dentist-fitted mouthguards are consistently identified as the most protective option for athletes across all sports disciplines.

Dentist-Fitted Mouthguards

What sets a dentist-fitted mouthguard apart is precision. Your dentist ensures the appliance conforms exactly to your individual tooth arrangement — meaning every surface is correctly supported, every gap accounted for. This accuracy is what enables the mouthguard to genuinely cushion a blow rather than simply sitting loosely in the mouth when impact occurs. A well-made custom mouthguard can also prevent biting injuries to the tongue, lips, and cheeks — injuries that often result from the jaw snapping shut unexpectedly during a collision.

Benefits of Dentist-Fitted Mouthguards

Choosing a custom-made mouthguard over a ready-made or boil and bite alternative delivers three clear advantages:
  • Superior protective performance against impact forces
  • Greater comfort for breathing, speaking, and wearing over extended periods
  • Durable, professional-grade materials built to last the season

Custom-Made Mouthguards

Dentist-fitted mouthguards are also referred to as custom-made or custom-fabricated mouthguards. They represent the most clinically effective dental appliance available for preventing traumatic oral injuries in sport.

Mouthguards and Dental Braces

If you or your child currently wears dental braces, speak with your dentist before purchasing any mouthguard. Specialised options exist for patients undergoing orthodontic treatment, and your dentist can advise on the most appropriate solution for your circumstances.

A Mouthguard is Worth the Investment

When you consider the cost of treating a fractured tooth, replacing a lost tooth with an implant, or managing soft tissue injuries — all of which can run into thousands of dollars — the upfront cost of a custom-fitted mouthguard looks extremely reasonable. Protecting teeth before an injury occurs is always the smarter financial decision.

Mouthguard Recommendations

  • Treat a mouthguard as essential equipment, not an optional accessory
  • Wear it for all contact sports and high-risk activities including skateboarding and BMX
  • Clean it with a soft toothbrush before and after every use
  • Rinse in mild soapy water, allow to dry thoroughly, and store in a ventilated case
  • Never leave a mouthguard loose in a sports bag — always return it to its container

Mouthguard Don'ts

  • Do not chew on your mouthguard — it compromises the fit and material integrity
  • Do not wear a retainer at the same time as a mouthguard
  • Never clean or soften a mouthguard with hot water — it will distort the shape

Contact Dental Nook to arrange a fitting for your custom mouthguard — the best investment you can make in protecting your smile on and off the field.
