There are some anecdotal evidence that banana peel can whiten teeth when rubbed continually on teeth. Banana is rich in potassium, making them a great snack to eat anytime. Most people prefer to make a delicious soft serve with frozen bananas. However, there are some unfounded claims that the back of a banana peel can whiten your teeth in sort of a dramatic way.
According to a popular pin on Pinterest, and other online posts, if you simply rub your teeth with the inside of a banana peel for 2 minutes, it can remove stains on your teeth and make them multiple shades whiter.
According to Pinterest: “To whiten teeth with banana peel is very safe and healthy for teeth as banana peels are a wonderful source of minerals and vitamins. They do not have the abrasiveness that other natural whiteners have and best of all they are inexpensive. 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.”
Most people who have tried it claim it doesn’t work at all. I have equally used it for over two months consecutively, it didn’t work. My teeth still retained the same shade as it was before I started using it.
