3. Whiten Your Teeth
There are lots of expensive ways to whiten teeth, and a lot of them use harsh bleaching agents that can actually wear away your enamel. This weakens teeth and can cause sensitivity. But guess what? Banana peel can whiten teeth naturally and gently due to its potassium content.
You don’t even have to chew the peel, but rather rub the inner side on your teeth every day for about two weeks. Results should start to show up after a handful of treatments.
