Most brushes are too big, long, and not ergonomic enough to fit into the nooks and crannies of your mouthguard to clean them properly. We specially designed the Koala Brush to make it perfect for cleaning athletic mouthguards and dental devices. The Secrets in the Bristles Not too soft, not too hard, just right. Our nylon bristles are durable and on the stiffer side, which makes them more effective at cleaning and longer lasting. Two Tips are Better than One Dentures and dental devices always have those pesky nooks and crannies that are hard to clean. Our second pick head is perfect for deep cleaning. Ergonomics are Important Our handle is wide and thick allowing you to grip and apply pressure when cleaning. Our thumb groove allows you to apply force near the head for maximum cleaning efficacy.
