Mouthpiece rubbing gum

[Land Fish]

I've used a Sea Cure for many years, extremely comfortable and secure, they don't wear out

Err...sizing...?

ScubaPro website doesn't tell me the size of the mouthpiece... :/

I had what might be a similar problem where my mouthpiece made contact with my gum above my teeth and rubbed it raw. I solved that by slicing a little bit of the rubber off the mouthpiece where it was hitting my gum. That part of the mouthpiece isn't doing anything valuable, so if it hurts you, just remove it.

That's exactly my problem, and what I was going to do. But a friend who is an instructor suggested a new mouthpiece before I could cut the edge of the mouthpiece.

How did you make the smooth edge? Just with knife or something else? Thanks.

Hi @Land Fish

It will be the 1 or 2 depending on what regulator you have. SeaCure has a detailed list on their website Regulator Size Chart for SeaCure Custom Mouthpiece

Good diving, Craig

DGX sells an in house brand of moldable mouthpiece. Another area to look at is external loading due to the hose, I switch over to a flexible LP braided type of hose (again DGX) which greatly reduced the external loading on the mouthpiece to the point I also removed my hose swivel, I didn't need it anymore. I suffer from canker sores on my gums and for myself simply swapping to a high flex hose resolved my issues.

I had exactly your problem--to the point of actual gum erosion--and here's what helped me:

First, I got a comfo-bit mouthpiece. I didn't have to trim it but wouldn't have hesitated. A sharp razor knife should do the trick.

That still wasn't quite enough, however, and I eventually realized that part of the problem was the reg getting pulled toward my right because of the hose. I got a swivel that connects between the hose and the second stage, and find that I can usually adjust the angle of the hose sufficiently to relieve the tension.

Moldable mouthpiecec are great, but you should not place them on a longhose or octopus, as your buddy/teammate needs to breath from that

Or during buddy breathing in the DM course....but that's the way it was.
I got the moldable years ago after nearly having my mouthpiece blown away by current on an anchor line in Gulf of Mexico--another reason to get one.

With a pair of scissors. I was able to get it smooth enough that the problem is solved and I haven't had to move on to any of the other suggestions made in this thread.

As seahorse suggests, a swivel inserted between the tube and the second stage is another way around this because it'll allow you to change the angle of the mouthpiece in your mouth. My problem reared its head on a liveaboard so I went for the scissors method, and since I didn't have the problem after that have never gotten around to getting a swivel.

A moldable mouthpiece may not solve your problem if you mold it at a different angle than what your second stage gets forced into from the tension in the connecting tube.

Soft silicone mouthpiece, good thing. Moldable mouthpiece, good thing. Although when one got snatched out of my mouth, it was a disturbing feeling. (I still use it.) You can also take a Dremel tool and thin down (feather) the areas of the mouthpiece that are rubbing on your gum, or pay your dentist to do that. (Might do it as a courtesy.)

Bottom line if one doesn't feel good, try another. Even the expensive ones aren't really all that expensive.
