i was just wondering if there is a mouthpiece that would keep you jaw from getting so fatigued? i just started diving and i am looking at dive equipment and just thought I'd see if anyone had any ideas.
Regulator mouthpiece

Finding a mouthpiece that works for you is very much a trial-and-error process.
Some people really like the Seacure mouthpiece, which offers a customized fit.
On my Aqualung and Apeks regs, I have the comfo-bite mouthpiece which seems to work quite well. I've never noticed any jaw fatigue at all.
Newer divers tend to really clamp down hard on the mouthpiece for fear of it popping out of their mouth and leaving them without an air source. In practice, not much pressure is required to keep the mouthpiece in your mouth. Before replacing your current mouthpiece, I'd experiment with consciously relaxing the jaw during your next dive. This might work for you. Good luck.

I'm sure that others will have specific suggestions on mouthpieces. I don't know what mine are, but when they need to be switched out during their checkout/rebuilds, I tell them to replace with the same ones.
I did want to mention, though, that sometimes it can be the hose length and/or that some other piece of equipment (surface sausage/SMB) can be pulling/pushing on your hose that can make your mouthpiece uncomfortable. Or sometimes you're just holding your mouth too hard, and this will lessen with experience. I don't "chew" my mouthpieces at all, but I have seen some really chewed up ones!

+1 on the seacure mouthpiece. I have them on all of my regs.

Once you get more experience and relax more, the problem may well disappear and you will be comfortable with almost any quality mouthpiece.
I had one seacure mouthpiece and it helped when I was first starting. But since the mouthpiece costs more than most of my 2nd stages, I was hesitant to adopt if for all my regs.

.....I think I'd give up diving if there weren't SEACURES! ......I get 'em for about $ 21 each @ Scubatoys, so they're not quite as overpriced as they used to be when they were more like $30 each.....plus most divers only need to buy one anyway. I'll admit I've bought quite a few for the primary 1st-stages for a number of my regs....most recently converted a few over to the new BLACK colored ones...sweet!

If you go with a Sea-Cure make sure to trim the wings way back to where someone with a small mouth can breathe off it without gagging. Also when you bite down, do not bite very deep, or you will close your teeth too far together to get air through easily.

MIFLEX hoses are another possible solution that has been mentioned before in similar threads. They almost eliminate the stress of hose pull which decreases the effort needed to hold the reg.
I personally prefer the Comfo-Bite. I started with a Seacure, which I liked, but I find the Comfo-Bite to be MUCH MORE comfortable, and have converted all my reags to the Comfo-Bite. I simply reached a point where I didn't want a lot of mouthpiece in my mouth, yet I wanted the mouthpiece to feel secure. The Comfo-Bite does that (for me) much better than the Seacure, and for substantially less money than the SeaCure.
The suggestion that you should be sure the hose is of the appropriate length is VERY important. If your primary hose is (too) short, and you are trying to keep the mouthpiece in by more assertively clamping down on it, you can very quickly develop jaw fatigue.
The comfo bite mouthpiece (to second Colliam) is a great mouthpiece. You can leave your jaw loose, and the roof guard just sort of lets it hang there. It is the most comfortable mouthpiece that I have ever used, though admittedly I have never used a Seacure. Half of my regulators cost me 20 bucks so there is no way in the world I am paying that much for a dog-gone mouthpiece
