Night Guards Made Of

What's Your Kiry Night Guards Made Of?

A custom night guard is designed to avoid tooth damage caused by grinding or clenching and to take preventative measures such as sleep. Its effectiveness is well understood by those who suffer from bruxism and have used a night guard. Beyond its role as a physical barrier, the Kiry night guard, made of hybrid material with a soft interior for comfort and a rugged exterior for durability, also helps alleviate TMJ (temporomandibular joint) disorders and improves sleep quality by providing a balance of cushioning and protection. This design ensures you can rest easy, knowing that your teeth are protected and your comfort is prioritized, allowing you to relax and sleep soundly.

The Importance of Materials

          Understanding the materials used in Kiry night guards is essential for selecting a safe and effective product. Here are some commonly used materials and their characteristics:

Safe Materials

EVA (Ethylene Vinyl Acetate)

          EVA is a flexible, rubber-like material often used to create soft dental night guards. It offers excellent shock absorption and heat resistance. EVA's smooth and elastic nature makes it ideal for light teeth grinding and sensitive teeth, providing enhanced cushioning for the mouth. EVA is not considered a carcinogen and has no known adverse health effects.

Thermoplastic Copolyester

          This material is easy to mold, reshape, and recycle, making it widely used in healthcare, food, automotive, and other industries. Thermoplastic copolyester is environmentally safe and has superior UV and chemical resistance compared to other flexible materials. It is perfect for heavy grinders and clenchers due to its durability and robustness, providing strong protection while ensuring comfort.

Methyl Methacrylate (MMA)

          MMA is a chemical commonly used in the production of acrylic products. While it has been controversial in some industries, it is safely used in many consumer products, including dental devices. Properly cured acrylic devices pose no health risks, and soft night guards are typically MMA-free.

Materials to Watch Out For

BPA (Bisphenol A)

          BPA is a chemical that makes hard plastics in items like water bottles and food cans. Although its health risks are still debated, studies have linked BPA exposure to various health issues, including heart disease and diabetes. Most modern dental materials do not contain BPA, but looking for BPA-free labels is essential when choosing a night guard.


          Phthalates make flexible plastics and can be found in many household and personal care products. Research on their health effects is limited, but animal studies suggest they may affect reproductive health. Opting for phthalate-free night guards can reduce potential health risks.


          While most dental night guards do not contain latex, individuals with latex allergies must choose latex-free options. Latex allergies can range from mild rashes to severe reactions. Knowing your allergy status and selecting appropriate products is vital for safety.

Why Safety Matters

          Your health is essential. Before making Kiry night guards available to the public, they undergo a rigorous testing process that includes biocompatibility, durability, and user trials. This thorough testing ensures that the night guards meet the highest safety and quality standards, providing peace of mind and confidence in your purchase. This emphasis on testing should reassure potential customers of the quality and safety of our product.
