Do you feel jaw strain after diving? Does your second stage regulator mouthpiece bother you? If so, changing your regulator mouthpiece style may make diving more comfortable. Before swapping out your mouthpiece, keep a few things in mind:
- Be sure that the new mouthpiece will fit on your regulator's second stage, as not every mouthpiece will fit every regulator.
- Many of the regulator mouthpiece styles are available in a variety of materials. The differences in material can effect your comfort.
- Once you find a regulator mouthpiece style that suites you, buy several mouthpieces and keep the spares in your save-a-dive kit.
Tech Tip: Inspect Your Regulator Mouthpiece
When is the last time you gave any thought to your regulator mouthpiece? Our service technicians tell us one of the most commonly damaged parts they discover during routine maintenance on a regulator second stage is the mouthpiece itself.
Many divers bite down much too hard on the mouthpiece, particularly if it is a poor fit. Besides the fact that biting too hard may cause the diver to climb out the water with an annoying headache, we even find bite tabs completely missing from the mouthpiece where they have been literally 'chewed off'. If that's happening to you, consider trying a different style of mouthpiece.
A more subtle damage often responsible for second stages 'breathing wet' is an almost invisible tear in the mouthpiece, just past the mounting lip on the second stage body near or under the cable tie. These often can't be seen unless you stretch the mouthpiece by hand and inspect in bright light.
