Binding of Isaac: Rebirth Wiki

Added in Repentance

Jawbreaker is a trinket added in The Binding of Isaac: Repentance.


  • Adds a 10% chance to fire teeth that deal 3.2x Isaac's damage; mechanically identical to the passive item Tough Love Tough Love.
    • The chance for this to occur increases with Luck. The activation rate is equal to 1/(10 - Luck). At base Luck (0), the chance is 10%, maxing out at 100% at 9 Luck[1].


  • This trinket is identical in function with Tough Love Tough Love, so all interactions with that item apply to this trinket as well.


  • Tough Love Tough Love: Activation rates are individually applied to each tear, effectively allowing for higher amounts of teeth. However at 9 Luck, this trinket is no longer needed, as Tough Love will already guarantee that every shot is a tooth at that point.


  • This trinket made its first debut in the Community Remix mod for Flash Isaac, previously being called The Jaw Breaker.
