Boil and bite mouthguards offer a convenient, affordable way to protect teeth during various activities. These guards become custom-fitted after being softened in hot water and molded to the user’s bite, providing a personalized shield.
They are a popular choice for athletes and individuals seeking protection without the expense of custom-made options, offering a balance between cost and effective impact absorption.
What is a Boil and Bite Mouthguard?
Boil and bite mouthguards represent a type of protective oral appliance designed for individuals participating in sports or activities where dental injuries are a concern. Unlike custom-made mouthguards created by a dentist, these are initially manufactured in a generic shape and require a simple, at-home molding process to achieve a personalized fit.
The core principle involves softening the thermoplastic material of the mouthguard by immersing it in hot water – hence the “boil” aspect. This increased flexibility allows the user to then bite down onto the softened guard, shaping it to the contours of their teeth and gums.
Once cooled, the mouthguard retains this customized form, providing a protective layer against impacts and reducing the risk of dental trauma. They are often constructed from layers of materials like Drufosoft, ensuring shock absorption and a secure fit.
Why Use a Boil and Bite Mouthguard?
Boil and bite mouthguards are a practical solution for safeguarding oral health during physical activity. They significantly reduce the risk of dental injuries, including chipped, fractured, or dislodged teeth, as well as cuts to the lips and gums. By absorbing and distributing impact forces, they minimize the potential for concussions and jaw joint injuries.
These mouthguards are particularly beneficial for athletes in contact sports like boxing, MMA, and football, but also offer protection in non-contact activities such as basketball and hockey where accidental collisions can occur.
Compared to stock mouthguards, the custom fit achieved through the boiling and biting process provides superior comfort and protection, ensuring a secure fit that stays in place during vigorous movement.

Understanding the Materials

Boil and bite mouthguards commonly utilize materials like EVA (ethylene-vinyl acetate) and Drufosoft laminates, prioritizing shock absorption and a secure, comfortable fit for optimal protection.
Common Materials Used in Boil and Bite Mouthguards
Boil and bite mouthguards predominantly feature Ethylene-Vinyl Acetate (EVA) as their core material. EVA is a thermoplastic copolymer known for its flexibility, durability, and excellent shock-absorbing properties – crucial for impact protection during sports and activities. Some higher-end options incorporate multi-layered constructions, like those from Dreve, utilizing Drufosoft laminates.
These laminates, often consisting of two or three Drufosoft films manufactured under high pressure (6 bar), guarantee optimal shock absorption and a consistently firm fit. The layering enhances the mouthguard’s ability to dissipate force, minimizing the risk of dental and jaw injuries. The quality of the lamination is paramount, ensuring long-lasting protection and a secure, comfortable experience for the wearer;

Use a slotted spoon or tongs to remove the mouthguard from the hot water. Be cautious, as it will be very hot! Gently shake off any excess water droplets. The mouthguard should now be pliable and moldable, ready for the next step. Work quickly, as it will begin to cool and re-harden relatively fast.
Step 3: Molding to Your Teeth
Place the softened mouthguard into your mouth and gently bite down, ensuring it covers all your upper teeth. Use your fingers to press the mouthguard firmly against your teeth and gums, molding it to the contours of your mouth. Focus on creating a secure fit around the molars and canines.
Suck in your cheeks to create a vacuum, helping the mouthguard conform to the shape of your mouth. Maintain the bite for the duration recommended by the manufacturer – usually around 30 seconds to a minute. Avoid talking or moving your jaw excessively during this process to ensure an accurate impression.
Step 4: Cooling and Setting the Fit
Remove the mouthguard from your mouth and immediately place it into a container of cool water. This stops the molding process and sets the custom fit. Allow the mouthguard to cool completely in the water for several minutes, ensuring it retains its new shape.
Once cooled, try the mouthguard again to check the fit. It should feel snug and secure without being overly tight or causing discomfort. If the fit isn’t satisfactory, you can repeat the heating and molding process once or twice, following the manufacturer’s instructions carefully. A well-fitted mouthguard is crucial for optimal protection.

Ensuring a Proper Fit
A secure fit is paramount for effective protection. The mouthguard should stay in place during activity, allowing comfortable breathing and clear speech without dislodging.
Checking for Comfort and Security
After molding, thoroughly assess the mouthguard’s fit. Gently bite down to ensure it conforms snugly to your upper teeth, without causing any immediate pressure or discomfort. Attempt to speak; the guard should allow reasonably clear speech, though some minor alteration is expected.
Crucially, try to dislodge the mouthguard with your tongue and jaw movements. It should remain securely in place. If it easily comes loose, remolding is necessary. Check for any sharp edges or areas that irritate your gums or cheeks; these require further softening and adjustment during a repeat molding process.
A well-fitted mouthguard is essential for protecting your teeth, gums, and jaw during sports. It should feel comfortable and secure, allowing you to breathe and communicate effectively.
Troubleshooting Fit Issues
If the mouthguard feels too bulky, reheat and remold, using less material initially. For a guard that’s too tight, briefly reheat and gently try to expand it while molding. If it doesn’t cover enough teeth, ensure you’re fully submerging it during the heating process and applying sufficient biting pressure during molding.
Persistent looseness indicates insufficient material or improper molding. Repeat the entire process, ensuring complete submersion and firm, even pressure. Sharp edges can be smoothed by briefly reheating the specific area and gently pressing it against a cool surface. Remember, multiple attempts may be needed to achieve a perfect fit.
Don’t force a fit; prioritize comfort and security.
