Yes — you read that right! Don’t throw away that banana peel just yet. It contains potassium, magnesium, and manganese, which can help remove surface stains and naturally whiten your teeth without harsh chemicals.
How to Use It:
- Choose a ripe banana (not overly brown).
- Peel it and use the inner white side of the peel.
- Gently rub the peel on your teeth for 2 full minutes.
- Keep your mouth open — don’t let lips touch your teeth.
- Let it sit for another minute.
- Brush your teeth normally with your regular toothpaste.
