OPRO

OPRO is a mouthguard specialist with a UK-facing online store that prices in pounds. OPRO says it has been operating "since 1997" and has sold over 15 million mouthguards worldwide.

Its Instant Custom-Fit guards are moulded at home with OPRO's own impression tray. OPRO sells each design in three protection tiers and recommends the thicker Enhanced tier, or Ultimate, for boxing. It also sells separate versions for braces.

OPRO's site also names an "OPRO X UFC" partnership and a "King's Award for Enterprise: Innovation Winner 2026".
