The Best Materials Used in Mouthguards and What They Mean for You

When choosing the right mouthguard—whether for sports, sleep, or medical reasons—the material it’s made from plays a critical role in comfort, durability, and effectiveness. With a growing demand for high-quality mouthguards in Dubai, understanding the science behind different materials can help users make more informed decisions. From basic thermoplastics to medical-grade polymers, each material brings unique benefits depending on the intended use. A well-informed choice ensures both protection and long-term usability.

Ethylene Vinyl Acetate (EVA):

Ethylene Vinyl Acetate, or EVA, is the most common material used in mouthguards, especially for athletic purposes. EVA is a soft, flexible plastic that is ideal for custom-molding to the teeth. It is shock-absorbent and can cushion heavy impacts without cracking or breaking. Most boil-and-bite and custom-fit guards are made from this material.

Advantages of EVA include:

• Excellent shock absorption

• Comfortable and flexible fit

• Easy to mold with heat

• Lightweight and non-toxic

This material is a preferred choice for those needing mouthguards in Dubai for high-impact sports like boxing, rugby, or hockey.

Polyvinyl Chloride (PVC):

Polyvinyl Chloride is used in some stock or lower-cost mouthguards. While it offers some level of protection, it is not as flexible or comfortable as EVA. PVC tends to be stiffer, which may lead to discomfort or difficulty breathing during wear. Additionally, PVC may contain phthalates unless specifically labeled as phthalate-free.

Considerations with PVC:

• More rigid than EVA

• Less suitable for custom molding

• Generally used in basic or stock guards

• May raise health concerns if not BPA-free

PVC mouthguards are typically used for short-term needs or as emergency backups, but they are not ideal for long-term or professional use.

Silicone Rubber:

Silicone-based mouthguards are soft, hypoallergenic, and highly flexible. They are commonly used for individuals with sensitivities to plastics or who need added comfort for prolonged use. While not as durable as EVA under heavy impact, silicone is often favored for night guards or those with TMJ issues.

Benefits of silicone include:

• Excellent comfort for long-term wear

• Hypoallergenic and latex-free

• Flexible and soft on the gums

• Low risk of irritation

Silicone mouthguards are ideal for people with jaw tension or those seeking mouthguards in Dubai for nighttime use and bruxism.

Dual-Laminate Materials:

Dual-laminate mouthguards are made from two layers: a soft inner layer for comfort and a harder outer layer for durability and shock resistance. This combination makes them highly effective for both sports and night use, offering a blend of protection and wearability.

Dual-laminate features:

• Strong outer shell resists high impacts

• Inner layer provides custom fit and comfort

• Great for severe bruxism or high-contact sports

• Longer-lasting than single-material guards

These guards are often custom-made and recommended by dentists for individuals needing both structural support and comfort.

Medical-Grade Thermoplastic:

Medical-grade thermoplastics are used in high-end, custom mouthguards and oral appliances. These materials are non-toxic, BPA-free, and designed to conform precisely to a dental mold. Their durability and hygiene standards make them suitable for extended wear and sensitive patients.

Key properties:

• Safe for prolonged oral contact

• Precision fit with professional molding

• High resistance to wear and tear

• Ideal for medical-grade night guards and apnea devices

Patients with medical conditions or those requiring long-term solutions often opt for guards made from medical-grade thermoplastic for superior safety and comfort.

Acrylic Resin (Hard Guards):

Acrylic is typically used for hard night guards, especially in treating TMJ disorders. These mouthguards do not flex and are designed to hold their shape over time. While not suitable for sports, they are effective for keeping the jaw aligned during sleep.

Advantages of acrylic guards:

• Highly durable and long-lasting

• Excellent for managing severe bruxism

• Maintains jaw position effectively

• Easy to clean and maintain

These guards must be custom-made by dental professionals and are not typically used for athletic purposes.

BPA-Free and Latex-Free Formulations:

With rising concerns over chemical exposure, modern mouthguards are often made with BPA-free and latex-free materials. These formulations ensure that users—especially children and those with allergies—can use them safely.

Why this matters:

• Reduces risk of allergic reactions

• Safer for long-term use

• Complies with health regulations

• Preferred for pediatric and sensitive users

When selecting mouthguards in Dubai, always look for labels that confirm the absence of harmful chemicals and allergens, especially if the guard will be used daily.

What Material Choice Means for You:

The right mouthguard material depends largely on your personal needs, usage frequency, and comfort preferences. Consider the following when choosing:

• For sports: EVA or dual-laminate materials offer the best balance of comfort and protection

• For night use (bruxism or TMJ): Silicone, dual-laminate, or hard acrylic provide targeted relief

• For sensitive users: BPA-free, latex-free, or medical-grade materials reduce risk of irritation

• For temporary use: Stock PVC options are inexpensive but should be used sparingly

Investing in the correct material ensures long-term protection, better sleep, and peace of mind—especially if your mouthguard will be a daily necessity.

Final Thoughts

The material used in your mouthguard is just as important as the fit or design. From EVA and silicone to dual-laminate and medical-grade plastics, each type offers unique advantages depending on its purpose. If you're seeking mouthguards in Dubai, understanding these material differences helps ensure you select a device that’s not only effective but also safe, comfortable, and tailored to your lifestyle. A well-informed decision today can prevent discomfort and dental damage tomorrow—making the right material the foundation of smart, proactive care.
