Why do banana peels whiten teeth

Brush your teeth as usual with a natural toothpaste or you can use the banana peel first and then brush. Take a piece of the inside of the banana peel and gently rub around on your teeth for about 2 minutes.

Does it work? Well, I tried it, and while I'd love to tell you that it worked like a charm, it did not. Our teeth and bones are made of hydroxyapatite HA molecules. Pure HA is snow-white. HA molecules are made of calcium, phosphorous, hydrogen, and oxygen atoms. Our saliva contains all of these atoms. Every day our mouths cycle from acidic to basic alkaline , and with these cycles, new microscopic hydroxyapatite molecules are formed on the surfaces of our teeth.

Maybe the claim is due to bananas being acidic and dissolving the surface of teeth, therefore, also removing surface stains. An acidic fruit, rubbed against your teeth over and over, may make the teeth appear a little whiter because the acid would dissolve away the surface of the tooth, and of course, any surface stain would be removed along with a surface layer of your teeth.

But of course, that will damage the teeth over time by dissolving the surface. Foods and beverages we all consume often contain fluoride, which attaches to the HA of teeth. So at least the surfaces of our teeth have fluoride. Fluoridated tooth structure HA starts to dissolve at pH 4. Bananas are pH 4. Banana peels have an even higher pH, closer to pH 7. So, if you want to take a more aggressive approach to whiten them there are multiple over-the-counter products, and your dentist can give you the professional tooth whitening treatment with immediate results the same-day.
