Banana Peel
No! They’re not waste! Rub a banana peel on your teeth for two minutes (the direction does not matter). Banana peel contains some essential minerals like potassium, manganese, and magnesium that penetrate into the teeth, helping in whitening them.
Strawberries
Take one or two strawberries, mash them up and apply them on your teeth; rinse it off after two minutes. Fruits are a rich source of a natural enzyme known as malic acid – the key component in teeth whitening toothpaste. Also, the fiber found in strawberries acts as a natural cleanser and helps remove bacteria, specifically from the mouth and teeth.
Lemon
The high acid levels contained in the peel of the lemon work as a powerful whitener or bleaching agent.Rub the lemon peel or apply its juice to the teeth and rinse it off after two minutes. Don’t leave it on for a long time as lemons are highly acidic and may lead to enamel erosion.
Carrots
Raw carrots are very effective when it comes to scraping off plaque from your teeth. They are also known to be natural whiteners. Apart from these, they kill the bacteria by maintaining the acid-alkaline balance of the mouth.
Baking Soda
One of the safest and strongest teeth whitener is baking soda. It is an excellent acid neutralizer and helps to remove stains while protecting the enamel. Apply baking soda on your teeth using a toothbrush and rinse it off after two minutes. You will get sparkling white teeth instantly!
