I love these mouthguards. I love them so much, that I bought the company! As the owner of ProformGuard, I have carefully picked the very best in materials, manufacturing practices, and equipment. Combine that with a careful eye for detail which is required from all of our “First Impression Affiliates” as well as our dental lab techs, we put out the finest vacuum formed products available for the cost. From sport mouthguards to replacing lost retainers, making nightguards, as well as teeth whitening trays, we make high-quality, comfortable products. If we don’t earn 5 stars from you, I want to know!
