I loved the theme and aesthetics, made me think of inscryption a bit.
I think its not fully used though, I have the same problem as other game of this jam is that i have 0 control or impact on the game.
Roll, maybe win, maybe loose... fun ?
You have a great base concept, maybe i could have gambled my teeth, maybe i can put them back when i win and the goal is to get ALL your teeth back, maybe some teeth are gold teeth and they have extra value, maybe some teeth are magical and have some special effects.
Just anything so i have any kind of impact on the outcome so i get invested in the game, right now, i couldn't care less if i won or lost since i had no impact on that outcame, i feel neither proud or disapointed by my performance, i just click and watch.
Removing teeth was as satifying as it was disturbing.
So with a little bit of changes, i think you could have a pretty fun concept :)
