I have fairly severe bruxism (teeth grinding). I've fractured several teeth over the years. My previous dentist gave me a standard mouth guard. I continued to fracture teeth. My current dentist recommended a device called an "NTI-TSS" (nociceptive trigeminal inhibitor tension suppression system). It's a tiny mouth guard that fits over just the front teeth. The theory is that the front teeth resist clenching whereas the back teeth are triggerred to clench when they sense something to chew (biting vs chewing).
In any case, my NTI is starting to exhibit an unpleasant odor. I think the problem is that it has developed some tiny cracks between the hard outer shell that stop the clenching and the inner, softer material that fits snugly around the teeth. These cracks are now serving as breeding grounds for bacteria. This problem didn't occur for the first several years I had the device, which is why I think it is related to a deterioration of the seal.
I've tried soaking it in alcohol and various antibacterial rinses. This cures the problem for a few days. I would like a more permanent solution.
Here's my question. Is there a material that I can use to seal the whole device? I'm thinking of some type of acrylic that would seep into all of the cracks and form a barrier to the bacteria getting back in there. I'd soak it in alcohol to kill the bacteria than apply the seal.
Whatever it is would have to be safe to have in my mouth every night.
If that fails, I guess I'll go get a new device. They are about $500, so if I can make this one last longer, I'd like to.
Thanks for any suggestions.
