1. Use baking soda
Baking soda is a natural teeth whitener and included in many kinds of toothpaste, such as the Arm & Hammer brands.
Try mixing a quarter teaspoon of baking soda with water and applying this to the teeth with your toothbrush.
Alternatively, add the baking soda to a cheap toothpaste. It will not damage your teeth in any way but will make them look gradually whiter over time.
2. Eat strawberries
Due to the Malic acid, which is a natural cleanser, these summertime treats can naturally whiten your teeth.
3. Warm salt water
Salt water helps both whiten your teeth naturally and looks after your gums (as it is a natural antibiotic).
Mix a teaspoon of salt in a cup of warm kettle-boiled water and use it as a mouthwash.
4. Eat white foods
Food colorings stain teeth by binding to the tooth surface
The whiter the foods you eat the whiter your teeth will be. Eat chicken, rice, and fish. Avoid pigmented foods such as beetroot, blueberries, carrots and Chinese/Indian takeaways (which have lots of turmeric and food colorings in them).
5. Eat apples
Apples are one of the natural teeth cleansing fruits as they contain Malic acid - a natural cleanser.
6. Drink water or milk
Try to get your two liters a day and you'll see a noticeable improvement
You can also drink lemonade or tonic water, and remember, white wine is better than red wine (for teeth at least).
Calcium in milk also helps strengthen tooth enamel and structure as well as the jawbone. Water is a natural cleanser washing away plaque.
7. Eat cheese
Cheese is another great naturally cleansing food that can strengthen the teeth.
Cheese contains calcium and also has a cleansing surface structure, especially hard cheese like cheddar.
8. Use coconut oil as a mouth rinse (oil pulling)
Use a tablespoon of coconut oil and swirl in the mouth for as long as you can.
The longer the better, try to hold on for around 15 minutes.
This practice can help remove bacteria and helps prevent plaque and stains from sticking to teeth by lubricating them.
