For whiter teeth without the chemicals, look no further than your fruit basket. Want to know our latest cheap little all-natural secret? Bananas. Not only are they a healthy, delicious snack full of potassium, vitamins and dietary fibre but they're also great for brightening your smile. Simply rub the inside of a banana peel in a circular motion on your teeth for about two minutes. Yes, in our experience you'll get a mouthful of what feels like banana peel pulp but this is easy to rinse away and you'll notice a difference - smoother, cleaner feeling teeth even after just one application. Twice a day is recommended. After about two weeks you should notice the whitening benefits. The minerals in the peel such as potassium, magnesium and manganese absorb into your teeth and whiten them. Banana peels are a safe, natural, affordable way to whiten your teeth - and they're easier on the environment than chemical formulas. Compostable toothbrushes and compostable floss picks are two more great ideas for keeping your teeth healthy and the planet too.
