How is banana peel whitening used?

The natural and most common homemade method of using banana peel for teeth whitening is as follows –

Choose the right banana and peel it

Choose a banana which is ripe with little or no black spots on its surface. Bananas at this stage are rich with minerals.

You can choose to take a single strip or the entire peel of the banana according to your needs. Usually, a single strip is sufficient for whitening the teeth in one sitting.

While peeling make sure to start from the top of the banana to get most of the stringy banana bits that are attached to the peel.

Rub the peel on your teeth

Rub the fleshy inner side of the peel against the teeth. Keep rubbing until you feel and notice a paste-like layer forming on the surface of the teeth.

Once all the teeth are covered with the banana peel paste, let it remain like that for about two to five minutes.

While allowing the paste to sit on the teeth, do not speak or move your lips too much as it will remove the paste from the tooth surface.

Brush your teeth

Use a soft-bristled toothbrush and brush your teeth with the banana peel paste present on the surface of your teeth.

Be careful while brushing and do not hurt the gums around. Use gentle pressure while brushing in a circular motion for two minutes.

Rinse your mouth and brush your teeth with regular toothpaste if you wish to.


For noticeable results, repeat this method daily for at least two weeks. The results may vary from person to person as the enamel composition is different for everyone.
