Refund & Exchange Policy



  • The customer is responsible for taking a good impression that meets our requirements. The instructions and how-to video must be followed very precisely. 
  • Dental Impression Kits, Replacement Putty, and Shipping Fees are non-refundable. 


If you have any issues with your mouthguard, you have 14 days from date of delivery to contact us. We will always do our best to get you taken care of. If you have issues with the fit, DO NOT cut or trim your mouthguard! Any cutting of the mouthguard by the customer voids warranty.
