GuardKit nightguards are individually handmade in a dental lab without an expensive visit to the dentist. The nightguards are custom made from two layers of clear EVA plastic by being moulded over the cast of the wearer's teeth.

A dental nightguard is a treatment option for teethgrinding (TMJ, bruxism) and is worn over either the top or bottom teeth providing a cushion between the upper and lower teeth preventing the loss of tooth enamel from teeth grinding.
