This is an odd request, but this forum has come up with amazing
solutions to odd requests so many times...
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
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.
Good suggestion. I'd recommend soaking in 'digestible' alcohol like
EverClear 190 proof. That way the residu will NOT harm you. But soaking in
alcohol is likely to destroy the plastics. Causes 'crazing' at the surface.
There is a 'commercically' available epoxy like goo that is used in the
Electronic industry to encapsulate 'anything' for implanting inside the
Sorry, don't remember the name but it sounds exactly like what you
describe. Look under FDA approved Medical Electronics encapsulation
Be sure to 'sterilize' as much as possible the item before encapsulating
though. bleach kills EVERYTHING - bacteria, mold, virii; and now Clorox
has some strange wetting agent added to their bleach.
I tried that and it mostly works, but it's messy and inconvenient. It
also tastes bad. And I think I remember asking the dentist about it and
was told that alcohol is not good for the plastic. I also tried soaking
it in a dental antibacterial rinse. Still messy.

You said the first one lasted "several years." For the sake of argument let's say the device lasted 5 years. That's $100/year, or about 27 cents per day to save you THOUSANDS of dollars on cosmetic dentistry.
Seems like a wise investment to me.
There is nothing you can soak this in that will permanently stop the bacteria growth, especially now that the bacteria have presumably gained a proverbial foothold down deep in the presumably porous foam core of the device.
There is nothing durable you can paint on this device that will not be poisonous to you, either.

You could try one of these
They are a lot cheaper than what the quacks try to sell you, so you
don't have much too lose and you do have a lot to gain.

I don't know about the ones in the URL above, but FTR when I
anticipated a fight, a mugging by someone I knew, I bought a mouth
guard meant for football players iirc.
I followed the instructions and heated it in very hot or boiling
water, waited the amount of time it said, then bit down on it to make
it mold to my teeth. And it did.
The guy never tried to fight me. I don't remember how tight it was
and I can't check because my teeth have moved around a bit.
In the store they only had one size, but on the web they probably have
enough sizes to fit anyone.
(I remmeber now. I had one that was meant to move my teeth into
position when I was 13 years old, the last step in having braces (at
the time. I think different methods are used now.) . It worked too
and I still have it 50 years later, but it wouldn't fit my mouth even
30 years ago, so I had to buy the other one.

Interesting suggestions. I'll give them a try. I've tried rinsing it
each morning in alcohol and a dental rinse without success. I think the
little buggers have gotten a foothold (do they have feet?) and unless I
get it sealed, nothing will work because of the environment it is in 8
hours a day.
I don't think rinsing it will help the critters deep in the cracks.
You gotta get the killer down where they are.
I'd try putting it in a bath of the strongest disinfectant you think
it will stand and pulling a vacuum on it with a seal-a-meal or some
such to suck the air out of the cracks to let the killer in when
you remove the vacuum.
You can even "boil" the liquid out of the cracks at relatively low
temperature, but you'll need a better vacuum than you can get out
of a kitchen appliance.
There are so many dentistry schools in the USA, many with
people trying to earn tenure through research, that you could
probably locate someone investigating mouth guards for
bruxism, and she might know the answers to most questions.
I can't tell how big the cracks are, but if they're small, it's not about
molecular size, it's about surface tension. A small amount of air
can completely prevent liquid from entering a crack.
The vacuum removes the air so the liquid gets sucked into the crack
when you remove the vacuum. You can do a similar thing with pressure
overcoming the resistance of the air pocket.
A more difficult problem is the mouth slime that's in there.
Maybe hit it with high pressure air to drive out some of the slime
before the vacuum.
I haven't read all of the responses in here, so my apologies if someone
has already suggested using a product like Polygrip, or anything that's
used to hold dentures in place.
It might be a bit hard to pull your mouth guard off, but if you pull
slowly it should come off without harming your teeth.
I went to the local hardware store. The only thing that looked like it
might work as a sealer was Super Glue or Crazy Glue (Cyanoacrylate).
When I have used it in the past to make repairs, I recall it penetrating
into cracks very rapidly and leaving almost no residue. I think it would
get into even the tiniest cracks and it would kill anything.
But is it safe to have in my mouth even after it is completely dry and
