DGX C-Bite+ Firm Mouthpiece

The C-Bite+ mouthpiece design, molded from high durometer FIRM hypoallergenic silicone, fits across the upper palate and holds easily in place, reducing the jaw fatigue some divers experience when holding the regulator in their mouths for extended periods.

It's an Apeks clone since the patent expired and @DiveGearExpress is bringing them in now. They're worth it.

I really like the Aqualung Comfo Bite mouthpieces. All silicon with a mouth "roof" bridge instead of just bite tabs..

You might be able to trim your present mouthpiece.

Once you use them, there is no turning back.

Make sure you get the Apeks, Aqualung or DGX versions. There are other clones out there that are way too soft and twist in use.

I’ve always used SeaCure mouthpiece. They are easily customized for your mouth. Buy one specific to your regulator. Follow the directions carefully by trimming if needed, dip it in boiling water, shake it and bite down as directed. They last a long time and are comfortable. You can remold them if you didn’t get it right the first time. There’s a video about them too. Last one I got on E-bay at a reduced price.

If you are using primary donate there can be an issue with gagging for the recipient with this type of mouthpiece especially if it is long. Obviously not a problem with alternate donate.

Get a Sea Cure, moldable mouthpiece. Rapidly approaching 300 dives on mine, they just fit your mouth.

There is also the Mares Jax which is softer, and has clones (DGX, Deep 6) that are half the cost.
Sea Cure is made out of harder material.
