Introduction: Cheap Comfortable Fangs

Picture of Cheap Comfortable Fangs

I can never find plastic fangs that fit my mouth properly. Here's a way to make inexpensive plastic fangs that fit your teeth and stay put.

Note: Not recommended for small children. Since these are individual fangs, rather than a full set, they are potentially a choking hazard.

Step 1: Materials

Picture of Materials

You'll need...
- low-temperature thermoplastic (a.k.a. "friendly plastic", Ultra high molecular weight polyethylene, UHMWPE). Should be able to find it at a craft store.
- denture adhesive
- a glass container
- hot (nearly boiling) water

Step 2: Melt Some Plastic

This plastic melts at about 150F. Put some in hot water and wait for it to soften. It turns transparent when melted.

Step 3: Make a Fang Shape

Take a blob of plastic and shape it into a rough fang shape. Don't worry too much about the exact shape yet. You can shape it better once it's in place.

Step 4: Fitting

Picture of Fitting

Shove the blob onto one of your canines and shape it to blend in with your other teeth.

If it doesn't come out to your liking, re-melt it and start over.

Step 5: Finishing Up

Remove the fang from your mouth and let it cool. It'll turn opaque when it returns to room temperature.

You should now have a plastic fang that fits your mouth perfectly. A small amount of denture adhesive will hold it in place.

coles3434 (author)tofuvampire2017-10-23

Honest-to-God i cannot find this crap anywhere except the internet. any ideas?

degroof (author)Father Christmas2007-12-13

I'm pretty sure the "boil-and-bite" mouth guards in sporting goods stores are made of the same sort of plastic. Might be worth a look. A lot of the stuff you find in craft stores is in strips instead of pellets. Usually with the beads and costume jewelry supplies.

You know how u buy the single fangs at the store with the caps and stuff how do u boil them????

I found it in a theatrical supply store in college, and I've seen it at the occasional craft store.

Where do you buy the materials?

wow i found out about this plastic years ago and forgot about it. icouldnt find it anywhere in my area and it was before the internet was ashopping mecca. i've bought scarecrow fangs before and they're good butthis is way cheaper and way more customizable. you could even mix insome glow powder for glow in the dark fangs.

maybe try one of those mold to your mouth mouthgaurds? They sell them rather widely and imma try it myself also

Sunny124613 (author)2009-10-21

 wow this would be a little better if you made a 
whole mouth casting, but i guess we will just have to make-do.

darby0malley (author)2009-10-21

nice toof degroof
ill try this one thanks

dnarby (author)2008-05-21

Awesome. I have an audition where I have to tape myself as a vampire for HBO. If I get the gig, I'll send you a signed copy!

imrobot (author)dnarby2009-09-30

just curious but, did you get it ?

dnarby (author)imrobot2009-09-30

Nah, but it was fun to do anyway, tnx!

Gage987 (author)dnarby2009-10-13

what was it for?

dnarby (author)Gage9872009-10-13

HBO True Blood promo.  Dang!  (I know).

Wish me luck, I might actually finish my own no-budge movie next year, and possibly get a chance to produce another.

gjsmith2009 (author)2009-09-30

How much of the plastic pellets did you use? I found a free sample of "Shape Lock" on's a little over 1oz. pkg. ... Do you think this would be enough for a set of fangs? Maybe two? The hubby and I really loved your idea! Thanks!

degroof (author)gjsmith20092009-09-30

I'm not sure how much I used but I just weighed out 1 oz of pellets and I'm pretty sure that should be plenty to make 4 fangs.

young_inventor (author)2009-04-08

cool I'm going to need this a lot, (IM trying to make the claw that sabertooth has u know off of x men)im going to freak out the kids at school. LATERS!! :]

poser (author)2009-02-26

kewlio!! xD

demonfox (author)2007-10-28

Yeah, made a set of these a while back from that polymorph stuff (thank you maplin) found that rather than mess around with adhesive all night, was to also make a bridge section like you'd get on a retainer. Doesn't affect speech at all and more difficult to lose. Plus, they give a much nicer bite, as my girlfriend will testify ;-)

dude those look suite they're begging for an instructable

zazuu (author)trebory62008-10-15

OMG WICKED.. its been a year.. did he make that instructable??

halfwaycrazy (author)trebory62008-02-21

Please, yes!

degroof (author)Pie_eata2007-10-29

I'll second that. Those are great fangs. I'd like to see how you got them shaped so nicely around the gum line.

i say make an instructable. the shaping is absolutely spectacular...

dnarby (author)2008-05-21

Just finished a pair, took me about 3 hours and four or five attempts to get them exaaaactly like I wanted. I ended up making single teeth, bridging them, then cutting away the bridge and as much material as possible to keep it from making me lisp. I think it also took me so long because I didn't want very big fangs, but rather something 'understated', harr! It took a lot of careful carving with a razor knife (be careful, once the material hardens it's pretty tough. I ended up doing a lot of trimming to get them to fit neatly up under the gum, and also to leave a natural looking space between my teeth.

skeptikool (author)2008-05-20

For one not looking for fangs but looking for whole or partial dentures, I should think this material might offer potential. Much would depend on its hardness, but even if one were to get a few months out of a set, one probably wouldn't mind repeating the process occasionally - dental fees being what they are. It might even be a good idea to make a couple of sets at the outset. Would the "lost wax" process used in jewelry-making be useful here? I have to admit to my interest being awakened when hearing of an aged, terminally ill person receiving a $17,000(Can) bill for dental work.

Totally WICKED!! I can't wait to try these!! They look fabulous!! Thanks for posting it!!

trebory6 (author)2007-10-29

NICE INSTRUCTABLE!! I wish I had seen this earlier and maybe I would have been a Vampire for Halloween! Thanks A LOT!

Kiteman (author)2007-10-28

I've seen this done with a plastic called Polymorph, which fuses at 62C (143F), the temperature of a cup of coffee.

That means you can put it in your mouth more quickly, and (it is claimed), you don't need dental adhesive to fix it to your tooth, just mould it in place a few minutes before you need it to be seen.
