Profile: Jaxeurope offers jax that eliminates friction on the gums and relaxes the jaw muscles. It safeguards the jaw articulation. The advantage of using our product is that while diving it provides significant relaxation of all the mouth muscles, especially those of the jaw. This relaxation gives greater safety for the diver, especially during longer periods under water. The mouthpiece, produced in a rubber material, is made up of a connector, collar and two support surfaces. The connector is the part that attaches the collar to the respirator. The collar has a hole in the center for the movement of air and is inserted between the lips and the teeth. The support surfaces extend inside the mouth & take up a position between the dental arches. When the diver bites on these they are held in position.
