Tough Love is a passive item.


  • Adds a chance to shoot a tooth instead of a tear, which deals greater damage (x3.2) than regular tears.


  • The chance to fire a tooth depends on the luck stat. The activation rate is equal to 1/(10 - Luck). At base luck (0), the chance is 10%, maxing out at 100% at 9 luck.
    • Added in Repentance Due to this, this item is extremely effective with The Lost The Lost or Tainted Lost Tainted Lost, as they are virtually guaranteed to find Added in RepentancePerfection Perfection after the third boss, making this item a free 3.2x damage multiplier with no downsides.


  • Added in Afterbirth †15►Apple! Apple!: With 14 luck, overrides Tough Love, though the razor blades do more damage anyways. With 13 luck, Apple and Tough Love each have about an equal chance to trigger.
  • 15►Brimstone Brimstone: Overridden by Brimstone.
    • Added in Afterbirth Occasionally fires Brimstone beam with damage multiplier of Tough Love.
  • 15►Cricket's Body Cricket's Body/Added in Afterbirth †15►Compound Fracture Compound Fracture: Teeth will split into smaller teeth.
  • Removed in Repentance15►Dr. Fetus Dr. Fetus: Bombs explode with the increased blast damage and radius of 15►Mr. Mega Mr. Mega.
    • Added in Repentance Adds a chance for the bombs to deal increased damage. See the page for the specific damage formula.
  • 15►Fire Mind Fire Mind: Adds flaming effect to the teeth, but without the chance of exploding.
    • Added in Repentance Tears will still explode.
  • 15►Ipecac Ipecac: Teeth explode with the increased blast damage of 15►Mr. Mega Mr. Mega.
  • 15►Mom's Knife Mom's Knife: Overridden by Mom's Knife.
    • Added in Repentance: Both damage multipliers apply, combined damage multiplier is x6.4.
  • Added in Afterbirth †15►Haemolacria Haemolacria: Tears will not appear as teeth but may still gain the damage multiplier.
  • Added in RepentanceJawbreaker Jawbreaker: Activation rates are individually applied to each tear, effectively allowing for higher amounts of teeth. However at 9 Luck, the trinket is no longer needed, as Tough Love will already guarantee that every shot is a tooth at that point.
  • 15►The Parasite The Parasite: Split tears will not turn into teeth.
  • Added in Repentance15►Spirit Sword Spirit Sword: Both the sword and projectiles can deal increased damage.
