How Do Mouth Guards for Sports Work?

Whether you’re on the field, in the rink, or at the skatepark, sports can be as unpredictable as they are exciting. A sudden fall, an unexpected hit, or even a clumsy collision can lead to dental injuries that are painful, costly, and sometimes permanent. That’s where mouth guards come in.

Mouth guards work by absorbing and distributing the force of impact to reduce the risk of injury to your teeth, jaw, lips, and tongue. They act as a soft barrier between your upper and lower teeth, helping to prevent broken teeth, cut lips, and other trauma that could keep you out of the game, classroom, or workplace.

For active kids, teens, and adults, a properly fitted mouth guard can be a smart way to protect not just your smile, but your confidence too.

Types of Mouth Guards

Not all mouth guards are created equal. The fit, material, and design can all impact how well a mouth guard protects your smile and how comfortable it feels while you wear it.

Stock Mouth Guards

These are pre-formed and ready to wear right out of the package. They tend to be the most affordable option but often come with downsides like poor fit, bulkiness, and difficulty speaking or breathing clearly during use.

Boil-and-Bite Mouth Guards

These are made from thermoplastic material. Once softened in hot water, they can be placed in the mouth and shaped using pressure from your teeth and tongue. They offer a better fit than stock options, but still might not provide the full protection or comfort of a custom-made version.

Custom Mouth Guards

Made by a dentist using a mould of your teeth, custom mouth guards offer the most comfortable fit and protection. They are particularly recommended for athletes involved in contact sports or those with braces or other dental work. These guards are designed to stay in place while you move, speak, and breathe, helping you stay focused on your performance, not your gear.

Why Mouth Guards Matter in Sports

Protecting Teeth from Trauma

Blunt force can cause teeth to chip, crack, or even be knocked out. A mouth guard cushions the teeth from direct impact, helping to reduce the severity of injuries that could lead to extensive dental treatment.

Preventing Jaw Injuries

A blow to the lower jaw can drive the mandible (the lower jawbone) into the upper jaw, potentially leading to fractures or joint damage. A properly fitted mouth guard absorbs this force and helps prevent that kind of compression.

Reducing Risk of Soft Tissue Injuries

Without a guard, your lips, cheeks, and tongue can be caught between your teeth during an impact. This can result in painful cuts and bruises. A mouth guard adds a layer of protection between the teeth and soft tissues, reducing the risk of lacerations inside the mouth.

Caring for Your Mouth Guard

Taking care of your mouth guard can help it last longer and stay effective:

  • Rinse it after every use: Use cool water (not hot) to rinse away bacteria and debris.
  • Clean it regularly: A toothbrush and mild soap work well. Avoid using toothpaste, which can be abrasive.
  • Store it properly: Use a ventilated case to allow it to dry out and avoid bacterial growth.
  • Check for wear: Mouth guards can wear down over time. Look for signs of thinning, cracking, or a loose fit.
  • Brush and floss before use: Cleaning your teeth first helps keep your mouth guard free from bacteria and buildup.
  • Bring it to your dental appointments: Your dentist can examine your mouth guard and let you know when it’s time for a replacement.

How to Choose the Right Mouth Guard

The right mouth guard for you or your child depends on several factors, including the sport you play, your age, and your dental structure. For the highest level of protection and comfort, it’s a good idea to consult your dentist.

Our team at Elevate Dental can create a custom mouth guard tailored to your unique smile. A custom fit helps the mouth guard stay in place, doesn’t interfere with speaking or breathing, and offers consistent protection during every play.

We also take your unique needs into account, whether that’s existing dental work, braces, or a history of jaw issues, so your guard feels good and works the way it should.

Elevate Your Smile with Protection That Fits

Mouth guards do more than protect your teeth; they help you play with confidence and peace of mind. Whether your child is starting hockey for the first time or you’re training for your next boxing match, a properly fitted mouth guard is a key part of your equipment.
