I use Thermoplastic for holding in my fangs. It's little plastic beads that you melt in a spoon with a cup of boiling water and then pour it into the fangs. Put the fangs on, mold a little of the wax onto a back tooth forming a "bridge" for a better fit. Once they are molded, you can pop them off when you want to drink or eat and pop them back on after. You can probably get them where you got the fangs. Foothills fangs come with the thermoplastic beads. I've never had any luck with the powder. I've never tried fix o dent either, but I know people do, but you can't take them on and off.
