Precision Fit A standard boil-and-bite mouthguard can be difficult to fit accurately, leaving it feeling loose, uncomfortable or needing to be remoulded. Silver changes that. Designed for athletes who train regularly, Silver combines dependable protection with OPRO's patented Fitting Tray technology. The tray helps guide the mouthguard into the correct position, allowing it to mould evenly around your teeth and create a secure, precise fit the first time—without the need to remould. Your Fit in Minutes Heat your mouthguard in hot water for 30 seconds. Place it into the patented OPRO Fitting Tray and bite down for 60 seconds. As you bite, the fitting tray directs force evenly across the mouthguard, helping it mould closely around your teeth for a secure, personalised fit. The result is a comfortable, secure Precision Fit mouthguard with dependable dual-layer protection, ready in minutes. Built for Regular Sport Every detail of Silver has been designed to deliver the right balance of comfort, fit and protection for regular sport. Its reliable core shape and mid-soft fins mould to the contours of your teeth, creating a secure, adaptive fit that becomes more personalised as you wear it. Advanced dual-layer construction provides strong impact resistance, giving you dependable protection session after session.
