Take a ripe banana. High amounts of potassium, magnesium, and manganese in bananas can help remove stains from teeth. Make sure the banana is yellow all over to ensure that it is ripe.
- This method will also take two to three weeks before you see noticeable results.
Peel the banana. You will only need a few small sections of the peel, so cut a few away after you peel the banana.
Rub your teeth with the inside of the peel. Spend about two minutes rubbing the peels all over your teeth. After that, let the juices sit on your teeth for 15 minutes.
Brush your teeth normally. Use your usual fluoride toothpaste and brush as you normally would. Be sure to remove any solid pieces of the banana if they’ve gotten stuck in your teeth.
Repeat this two or three times a week. Don’t use this treatment more often than that, or the acids from the banana could damage your teeth.
