Have you ever wondered about the materials used to create your dental night guard for teeth grinding and jaw clenching? In this video we discuss different night guard plastic types, what's considered safe and what to avoid. All Sentinel Mouthguard products are made with either EVA (ethylene vinyl acetate) or copolyester. Our products do not contain BPA, phthalates, MMA (methyl methacrylate), latex or silicone. Crafted in USA. Never outsourced. The Sentinel Hard Dental Night Guard is made of copolyester. It is an "acrylic-like" material and safe for nightly use. The Sentinel Soft Dental Night Guard is made using EVA (ethylene vinyl acetate). The Sentinel Dual Laminated Night Guard is a combo of both the soft material (inside of guard) and the hard copolyester material (outside layer). It is a semi-flexible night guard and safe for nightly use. Standard acrylic night guards do often contain MMA. Sentinel Mouthguards are an excellent alternative to acrylic products. This video is for informational purposes only. If you have questions regarding the material makeup of your dental night guard, please consult with your dentist or contact the manufacturer.
