Barbarian's Teeth

This set of dentures has teeth made of pure diamonds, and may be placed into a person's mouth, replacing (and permanently removing) their teeth. The item has 5 charges. While wearing the teeth, you can take a Magic action to expend 1 charge, and eat up to 1 cubic foot of inedible (but not directly damaging) material. For example, the wearer could eat a stone or a handful of grass, but not molten lava. The material tastes bland and boring, but is as nourishing as a small meal.

The dentures regain 1d4 expended charges when the wearer consumes a normal, hearty meal, with the exception of soup. The wearer finds soup distasteful. Removing the dentures does not restore the user's natural teeth.
