I give a BIG testimonial to Sea Cure and their mouthpieces.
In 1993, I was working a booth at DEMA, trying to drum up customers for my fledgling business. I never really paid attention, but I was next to the Sea Cure booth. At the end of the convention, as we were all breaking down our booths, the Sea Cure folks said, see you next year. I told them that I wasnt sure I would be back and they asked why.
I told them about a problem I was having, having a regulator in my mouth 3-5 hours a day was aggravating an already injured TMJ and it hurt so much that I was diving with my reg in my hand, only putting it against my mouth when I needed the next inhale.
It so happened that I was talking to the dentist that designed the mouthpiece, and he is a TMJ specialist. He looked at me, kind of funny and said Havent you listened to anything Ive said in the past three days????
Of course not, I was too busy with my own concerns and sales (DEMA costs a fortune, you have to make the most of every minute!)
So he sat down with me and started to explain about the dynamics of the jaw joint, the difference between biting and clamping and the affect on the muscles and the affect all this would have on the joint over time.
He then proceeded to give me an hour long lesson on the proper way to mold the mouthpiece and demonstrated on me. Then he told me that this one was a gift and happy diving.
Well, I used that mouthpiece, all that year, and all the next. That following year, my dive op was in a place to do some small amount of retail, and the Sea Cure booth at DEMA was the first I went to. You see, he saved my diving career, the TMJ healed, as much as TMJ can, the headaches were gone, I could eat, chew, and most importantly, dive for hours every day again. My dive op has never been out of stock on Sea Cure since.
There are many advantages to the SC mouthpiece, among them, they do NOT wear out, and you cant bite through them. My first did about 5000 dives, and I retired it along with the reg it was on, my second has done way more than 5000 dives and would probably outlast me, but Ill probably replace it just to have something new in my mouth.
The Sea Cure mouthpiece has solved many problems for many of my friends and divers over the years. I think it is the single best piece of dive gear you can buy.
