Malic acid is a natural enamel whitener. But here's the problem: Strawberries don't contain any ingredients that can actually lift stains to whiten your teeth. Rubbing strawberries on your teeth may create the illusion of whiter teeth for an hour or so, as your teeth are scrubbed clean from plaque and are gleaming.
The citric acid can give an illusion of whiter teeth for around an hour after you put on the strawberry paste as the paste does indeed remove some plaque from your teeth.
Strawberries contain malic acid, which is actually a good natural whitener for enamel – eating strawberries will actually help keep your teeth free of stains. Just be mindful that strawberry seeds can get stuck between your teeth, so make sure you floss after eating them.
Takeaway. Strawberries, watermelon, and dairy products may help whiten your teeth. These foods contain compounds with lightening properties. Pineapple and papaya also have proteolytic enzymes that dissolve stain-causing proteins on your teeth.
The quickest, most dramatic way to whiten is to get an in-office bleaching at a dentist's office. Using professional-strength hydrogen peroxide and special lights or lasers, your dentist can remove even deep stains in about an hour.
Lemon juice and bicarbonate of soda. Yes, that literally is all that you need for this great teeth whitening method. As you will discover, all you have to do is create a liquid paste using the two ingredients, and then apply it to your teeth for no longer than three minutes.
Use Hydrogen Peroxide and Baking Soda
Using this mixture removes bacteria and buildup of plaque to get rid of surface stains. Create a hydrogen peroxide and baking soda paste and use it to brush your teeth. After that, use water to rinse the mouth. You can also create a mouthwash using equal amounts of each ingredient.
Dairy products, such as cheese, yogurt and milk, contain lactic acid and the enamel-fortifying mineral calcium, which strengthen teeth while also whitening them.
A mixture of baking soda and hydrogen peroxide has been proven to work in some cases for instant results in a pinch. Combine two tablespoons of hydrogen peroxide with one tablespoon of baking soda. Mix it until it becomes a paste and use it to brush your teeth.
Apples and Citrus Fruit
An “apple a day” is also great for teeth too. Although not a substitute for brushing and flossing, eating an apple or other fibrus fruits like oranges, carrots or celery can help clean your teeth and increases salivation, which can neutralize the citric and malic acids left behind in your mouth.
Using hydrogen peroxide
Hydrogen peroxide is a mild bleach that can help to whiten stained teeth . For optimal whitening, a person can try brushing with a mix of baking soda and hydrogen peroxide for 1–2 minutes twice a day for a week.
However, a recent study published in the Journal of Operative Dentistry found that all strawberry and baking soda does is remove the plaque on your teeth, which can give the appearance of a whiter smile.
Unfortunately, there's no evidence to suggest that banana peels really do whiten teeth. While the minerals in bananas promote dental health, they're unlikely to brighten your smile.

#5: Helps Whiten Teeth
Does water whiten teeth? Yes, it can help keep teeth whiter! Drinking water helps ensure dark-colored beverages and foods do not leave stains on your teeth. Water washes the colored residues these foods and drinks leave behind.
It's a myth that you can safely whiten teeth with lemon juice and baking soda. Unlike toothpaste, baking soda is abrasive and will wear away your tooth enamel over time. Likewise, lemon juice is too acidic to sit on the surface of your teeth.
In most cases, the common cause for tooth discolouration is external staining as a result of drinking coffee, tea, or wine, or from smoking and other tobacco use.
Consuming Certain Foods and Drinks. “Certain foods that are high in tannins, such as red wine, are potential causes of yellow teeth,” notes Crest. Other teeth-staining foods include coffee, citrus fruits and juices, soft drinks, teas, berries, tomato-based sauces, curry, balsamic vinegar, and soy sauce.
Brushing your teeth is meant to remove harmful bacteria and plaque but not to whiten them. As recommended by your dentist, brushing twice a day is vital because it prevents cavities and tooth decay. Brushing alone will not whiten your teeth, though, and even whitening toothpaste only has a minimal effect on your teeth.
Salt acts as a surface abrasive and can definitely make teeth look whiter, but it can really damage your tooth enamel, and unfortunately once your enamel is damaged, it's damaged for life.
