8 Banana Peel
Bananas are a great source for Vitamin D, potassium, magnesium and calcium which will help your teeth be super healthy and much whiter and of course, remove tartar build-up.
This may seem a little uncomfortable, but you just take a banana peel and rub your teeth with it for around 2 minutes or so, massaging it in even in your palate to clean out all those impurities. Afterwards, you brush your teeth like normal with tooth paste and all.
