The SeaCure Custom Mouthpiece is a remoldable, custom-fit scuba regulator mouthpiece designed to conform to the individual diver's teeth, gums, and jaw. Its unique X-Type design reduces bulk and helps minimize gagging while providing improved support and retention of the regulator. The mouthpiece can be molded and remolded for a comfortable, personalized fit. It is made from durable, medical-grade ethylene vinyl acetate (EVA) and contains no latex or silicone.
