Dentemp Maximum Strength Temporary Filling Mix, 1 ea - 2pc

Holds better than the little canisters of putty I've been buying. Tastes awful, numbs your gums and tongue, which I wasn't completely expecting, and crumbles fairly quickly unless it has a rough surface to stick to. I have a broken tooth I used this on and it filled the hole part okay, but the side (where my tooth broke off) fell off almost immediately.
