Shock Doctor

Shock Doctor is a mouthguard maker, part of United Sports Brands. Its About page says the company began as EZ Guard Industries in 1993 and launched its "Gel Max" mouthguard in 2002. In 2015 it merged with McDavid Inc. to form United Sports Brands, which moved its global headquarters to Fountain Valley, California, in 2016.

Shock Doctor's own site (shockdoctor.com) is US-facing, and our research found no UK Shock Doctor storefront. In the UK, its guards are sold through retailers such as Minotaur Fight Store.

Its Nano Double is a double-arch boil-and-bite guard, and Shock Doctor states it is not compatible with braces.
