I have a plastic retainer for 3 weeks and it cracked today when I was
removing it -- I used a little bit more force than I needed.
The crack is at the front down the middle. It would cost > $100 to get a new
one. Is there any type of glue I can use that is harmless inside the mouth
The retainer still feel ok even with this crack. However, if I don't fix the
crack, it would probably get longer and eventually the retainer would break
I cannot afford to keep buying $100 retainer every month for the rest of my
life, so I'd like to learn how to repair them.
This from the JB Weld web site:
Q: Is J-B Weld toxic?
A: No. J-B Weld is non-toxic. However, we do not recommend consuming
That's good to know - don't eat it! ;)
The two components are individually mildly toxic, but the cured product
seems okay. Obviously, as with any two component product, thorough
mixing is essential for complete curing. Particularly important in the
Assuming the same material it was made with to begin with will also
act as a glue, that would likely be the best material.
Does your dentist make these things himself or does he send it to a
lab? I believe when I wore a retainer he made it himself. It seems
reasonable to me for him or his assistant to repair it. It doesn't
take the skill to make it that it does to repair it. The asst. can
use the same material he used in the first place, and apply a thin
layer over the crack and the area around it.
If you think this might happen again, he can sell you a bag of the
stuff (a powder?) at cost*** and the tech can show you how to mix it.
***That is a good question. $40? 100? How big is the bag? Buy
half a bag. Bring your own high quality ziplock.
If it is done at a lab, he can tell you where the lab is and he can
ask them to fix yours or sell you a bag of the stuff and show you how
to mix the stuff.
None of this will make you a dentist or a dental lab. They don't have
to worry about your competing with them.
When I was a kid, I put up with crap from my orthodontist. On only
one occasion but it still burns me when I think of it. Unless you
can't stick new stuff to old stuff, there's no reason he can't do this

I'd use super glue. They use it to glue cuts together instead of
stiches, so I definitely wouldn't mind the dried product in my mouth.
Whatever you use, you'll probably want some ultra-fine (like auto
finishing, 600+ grit) sandpaper to smooth out your repair - the tongue
is very sensitive to rough areas - I remember from my own retainer.
No, they don't use ordinary methyl CA glue for sutures. The surgical glue
is a non-methyl version of CA. Costs more so not a consumer item except as
the hideously priced OTC suture kit.
The methyl radical in the ordinary Super Glue is quite irritating to skin,
and toxic in large amounts, during curing.
But IF well-cured, epoxy or CA glue would be fine and appropriate for this
because the medical version was absurdly expensive. Didn't mention any
Agree with both of you - had heard that the consumer methyl version can
be irritating to the skin, but how many people glue their fingers
together with the stuff? I don't think the main issue in those cases
is whether it's irritating to the skin. Had also heard that it is
possible and not dangerous to use regular super glue instead of
stitches. Finally, I did specify that I wouldn't mind the dried
(polymerized, cured) product in my mouth, and I'll stick by that (no

I have used Super Glue on cracks on my feet and hands, at the suggestion of

Also, being rather clumsy, I have glued fingers together,, with no ill effects.
I doubt that putting super glue on a crack will accomplish anything, as
it is not bonding the two surfaces that meet each other. I would use it
as long as doesn't present a danger of breaking in the mouth. Wouldn't
hurt to call the lab that made it to see if they can repair the crack.
It should not have cracked in removing it from your mouth; I would whine
a lot to get a replacement.
Ditto. I get skin cracks on my thumbs
in the dry Chicago winters. These occur
at the nail corners. CA glue is the
best thing I've found. I use a very
on a toothpick and press the crack
together. It eventually heals. But most
important, the irritation from the crack
itself goes away after a minute after
applying the glue. Yes, the glue does
cause a little pinching when you first
apply it, however, it is nothing like
the contant irritation from the crack
