Here are 6 simple ways you can naturally whiten your teeth.

1. Practice oil pulling

Oil pulling is a traditional Indian folk remedy meant to improve oral hygiene and remove toxins from the body.

The practice involves swishing oil around in your mouth to remove bacteria, which can turn into plaque and cause your teeth to look yellow (2Trusted Source).

Traditionally, Indians used sunflower or sesame oil for oil pulling, but any oil will work.

Coconut oil is a popular choice because it has a pleasant taste and offers many health benefits.

Coconut oil is also high in lauric acid, which is known for its ability to reduce inflammation and kill bacteria (3Trusted Source4Trusted Source5Trusted Source6Trusted Source).

A few studies have shown that daily oil pulling reduces bacteria in the mouth, along with plaque and gingivitis (3Trusted Source7Trusted Source8Trusted Source).

Streptococcus mutans is one of the primary types of bacteria in the mouth that cause plaque and gingivitis. One study found that daily swishing with sesame oil significantly reduced Streptococcus mutans in saliva in as little as 1 week (8Trusted Source).

Unfortunately, no scientific studies have proven that oil pulling whitens your teeth. However, it’s a safe practice and worth a try. Many people claim their teeth are whiter and brighter after regular oil pulling.

To oil pull, put 1 tablespoon of coconut oil in your mouth and push and pull the oil through your teeth. Coconut oil is solid at room temperature, so you may need to wait a few seconds for it to melt. Continue the oil pulling for 15–20 minutes.

Be sure to spit the coconut oil into a toilet or trash can, as it could return to solid form once in your drain pipes and cause a clog.

Unlike many other tooth whitening methods, coconut oil pulling does not expose your teeth to acid or other ingredients that erode the enamel. This means it’s safe to do daily.

Summary Coconut oil pulling involves swishing oil in your mouth for 15–20
minutes to remove bacteria. Practicing this daily can reduce plaque and may
brighten your teeth.

2. Brush with baking soda

has natural whitening properties, which is why it’s a popular ingredient in commercial toothpaste.

It’s a mild abrasive that can help scrub away surface stains on teeth.

Additionally, baking soda creates an alkaline environment in your mouth, which prevents bacteria from growing

This is not a remedy that will whiten your teeth overnight, but you should notice a difference in the appearance of your teeth over time.

Science has not yet proven that brushing with plain baking soda will whiten your teeth, but several studies show that toothpaste containing baking soda has a significant whitening effect.

One study found that toothpastes containing baking soda were significantly more effective at removing yellow stains from teeth than standard toothpastes without baking soda. The higher the concentration of baking soda, the greater the effect

Furthermore, a review of five studies found that toothpastes containing baking soda removed plaque from teeth more effectively than non-baking soda toothpastes

To use this remedy, mix 1 teaspoon of baking soda with 2 teaspoons of water and brush your teeth with the paste. You can do this a few times per week.

You can buy baking soda at a grocery store or find it online

Summary Brushing with a paste made with baking soda and water can reduce
bacteria in your mouth and buff away surface stains.

3. Use hydrogen peroxide

Hydrogen peroxide is a natural bleaching agent that also kills bacteria in your mouth

In fact, people have been using for years to disinfect wounds because of its ability to kill bacteria.

Many commercial whitening products contain hydrogen peroxide, although at a much higher concentration than you will use.

Unfortunately, no studies have investigated the effects of rinsing or brushing with hydrogen peroxide alone, but several studies have analyzed commercial toothpastes containing peroxide.

One study found that a toothpaste containing baking soda and 1% hydrogen peroxide led to significantly whiter teeth

Another study found that brushing with a commercial toothpaste containing baking soda and peroxide twice per day led to 62% whiter teeth in 6 weeks

However, there are some questions regarding the safety of hydrogen peroxide.

While heavily diluted concentrations appear safe, strong concentrations or overuse can cause gum irritation and tooth sensitivity. There’s also concern that high doses may cause cancer, but this has not been proven

One way to use hydrogen peroxide is as a mouthwash before you brush your teeth. Make sure you are using a 1.5% or 3% solution to avoid side effects.

The most common concentration of hydrogen peroxide at the drugstore is a 3% solution. You can easily dilute this concentration to 1.5% by mixing equal parts peroxide and water.

Another way to use hydrogen peroxide is by mixing it with baking soda to make a toothpaste. Combine 2 teaspoons of hydrogen peroxide with 1 teaspoon of baking soda and gently brush your teeth with the mixture.

Limit the use of this homemade paste to a few times per week, as overuse can erode your tooth enamel.

You can buy hydrogen preoxide online.

Summary Hydrogen peroxide is a natural bleaching agent and can kill bacteria
in your mouth. You can use it as a mouthwash or mix it with baking soda to form
a whitening toothpaste.

4. Eat fruits and vegetables

A diet high in fruits and vegetables may be good for both your body and your teeth.

While they’re no substitute for brushing them, crunchy, raw fruits and vegetables can help rub plaque away as you chew.

Strawberries and pineapple are two fruits that have been claimed to help whiten your teeth.

Strawberries

Whitening your teeth with a strawberry and baking soda mixture is a natural remedy that has been made popular by celebrities.

Proponents of this method claim that the malic acid found in strawberries will remove discoloration on your teeth, while the baking soda will buff away stains.

However, this remedy has not been completely backed up by science.

While strawberries may help exfoliate your teeth and make them appear whiter, they are unlikely to penetrate the stains on your teeth.

A recent study found that a strawberry and baking soda mixture produced very little color change in teeth, compared with commercial whitening products

If you decide to give this method a try, limit its use to a few times per week.

Despite studies showing that a strawberry and baking soda paste had a minimal effect on tooth enamel, excessive use could cause damage

To use this remedy, smash a fresh strawberry, combine it with baking soda, and brush the mixture onto your teeth.

Pineapple

Some claim that pineapple can whiten teeth.

A study found that a toothpaste containing bromelain, an enzyme found in pineapples, was significantly more effective at removing tooth stains than a standard toothpaste

However, there is no evidence that eating pineapples produces the same effect.

Summary Certain fruits may have properties that help whiten teeth. Regularly
consume raw fruits and vegetables to help rub off plaque and keep your teeth
looking bright.

5. Prevent tooth stains before they happen

While your teeth naturally yellow as you age, some things can help prevent stains on your teeth.

Limit staining foods and beverages

coffee, red wine, soda, and dark berries are infamous for staining teeth.

That doesn’t mean you have to completely avoid them, but you should limit the amount of time these substances are in contact with your teeth.

If possible, drink beverages known to stain teeth out of a straw to prevent direct contact with your teeth.

Moreover, brush your teeth soon after consuming one of these foods or beverages to limit their effects on the color of your teeth.

Additionally, avoid smoking and chewing tobacco, as both can cause tooth discoloration.

Limit your sugar intake

If you want whiter teeth,

A diet high in sugar supports the growth of Streptococcus mutans, the primary type of bacteria that causes plaque and gingivitis

When you consume a sugary food, be sure to brush your teeth soon after.

Get plenty of calcium in your diet

Some tooth discoloration is caused by enamel eroding and exposing the dentin underneath, which is yellow. Therefore, anything you do to strengthen the enamel of your teeth will help keep your teeth pearly white.

calcium rich food such as milk, cheese, and broccoli, may elp protect your teeth from enamel erosion

Summary A healthy diet with enough calcium can help prevent your teeth from
becoming yellow. Brushing your teeth soon after you eat can also help prevent
stains.

6. Don’t underestimate the value of brushing and flossing

While some tooth discoloration naturally comes with age, it’s largely a result of plaque buildup.

Regularly brushing and flossing can help your teeth stay white by reducing bacteria in your mouth and preventing plaque buildup.

Toothpaste gently rubs out stains on your teeth, and flossing removes bacteria that lead to plaque.

Regular dental cleanings can also help your teeth stay clean and white.

Summary Daily brushing and flossing, along with regular cleanings at the
dentist’s office, prevent the buildup of yellowing plaque on your teeth.

Other methods that are not proven

There are a few other natural teeth whitening methods, but there is no scientific evidence to prove that they are safe or effective.

Some of the unproven methods include:

  • Activated charcoal. Brushing with pwdered charcoal supposedly pulls toxins
    from the mouth and removes stains from teeth.
  • Kaolin clay. Proponents of this
    method claim that brushing with clay helps remove stains from teeth.
  • Fruit peels. Rubbing orange, lemon,
    or banana peels on your teeth is claimed to make them whiter.
  • Apple cider vinegar. There is no evidence that using vinegar as a mouthwash helps whiten your teeth. On the contrary, it weakens the enamel and promotes tooth decay.

Advocates of these methods claim they make teeth significantly whiter, but no studies have evaluated their effectiveness. This also means that they have not been tested for side effects when used on teeth.

Summary Activated charcoal, kaolin clay, and fruit peels may help whiten your
teeth, but no studies have evaluated the safety or effectiveness of these
methods.

The bottom line

There are several natural methods to help whiten your teeth. Most of these remedies work by gently removing surface stains on your teeth.

However, most dentists offer whitening treatments that are much stronger than these natural remedies. They involve bleaching the teeth, which may be more effective for severe tooth discoloration. Overuse of any whitening product can damage your teeth.

Always check with your dentist about your options and which would work best for you.
