Peel a ripe banana.
Rub the inside of the peel on your teeth for 1–2 minutes.
Brush your teeth afterward.
It’s easy, it’s cheap, and it feels harmless—no wonder people want it to work!
But Does It Actually Whiten Teeth?
Short answer: No.
There is no scientific evidence that banana peels whiten teeth or remove stains.
Teeth whitening requires ingredients like:
Hydrogen peroxide
Carbamide peroxide
Mild abrasives (in toothpaste)
Banana peels contain none of these. While they are nutritious for your body, the minerals in the peel do not penetrate enamel, and rubbing the peel cannot dissolve stains.
In other words:
✨ Banana peels won’t harm your teeth, but they won’t whiten them either.
Why the Myth Feels Believable
Even though the method itself cannot whiten teeth, people sometimes claim it “works” because:
Their teeth look shinier from saliva moisture
They brushed right after, which naturally removes plaque
Lighting changes can make teeth appear brighter
But none of this equals true whitening.
