Official UFC x OPRO Tom Aspinall Instant Custom-Fit Mouthguard

Dentist-Level Fit

A traditional custom mouthguard usually means visiting a dentist, having an impression taken and waiting weeks for your mouthguard to be made.

Instant Custom-Fit changes that.

Designed and manufactured in OPRO's UK laboratory using our multi-patented technology, every Instant Custom-Fit mouthguard arrives ready for its final custom fit. Simply use OPRO's patented Impression Tray to mould the mouthguard closely around your teeth, creating an exceptionally detailed, personalised fit in around two minutes, without a dentist appointment.

Your Custom Fit in 2 Minutes

Heat your mouthguard in hot water for 30 seconds.

Bite into the patented OPRO Impression Tray for 60 seconds.

As you bite down, the Impression Tray harnesses the natural compression of your jaw, directing force evenly through the mouthguard and closely moulding it around the unique contours of your teeth with the same level of detail as a dentist's putty or scan.

The result is a slim, secure and comfortable custom-fit mouthguard with triple-layer protection, ready to perform in minutes.

Making Dentist-Level Mouthguards Accessible

Professionally made mouthguards have long been recognised for their close, personalised fit, but they also involve additional time, expense and a visit to the dentist.

Instant Custom-Fit removes those barriers. Its advanced fitting technology brings you an exceptional fit, comfort and protection at home, without the traditional dental fitting process. Trusted by professional athletes and elite teams, it makes advanced custom-fit protection more accessible than ever.
