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 with 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. Brushing with a paste made with baking soda and water can reduce bacteria in your mouth and buff away surface stains
Hydrogen peroxide is a natural bleaching agent that also kills bacteria in your mouth
In fact, people have been using hydrogen peroxide 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, there aren’t any studies to show 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 six 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.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.
Apple cider vinegar has been used for centuries as a disinfectant and natural cleaning product.
Acetic acid, which is the main active ingredient in apple cider vinegar, effectively kills bacteria. The antibacterial property of vinegar is what makes it useful for cleaning your mouth and whitening your teeth
One study performed on cow teeth found that apple cider vinegar does have a bleaching effect on teeth. However, they also found that vinegar may soften the teeth
The acetic acid in vinegar has the potential to erode the enamel on your teeth. For this reason, you should not use apple cider vinegar every day. You should also limit the amount of time that apple cider vinegar is in contact with your teeth
To use it as a mouthwash, dilute it with water and swish it around in your mouth for several minutes. Make sure to rinse your mouth with plain water afterward. Apple cider vinegar has antibacterial properties that may help whiten your teeth. However, overuse of vinegar can also erode the enamel on your teeth, so limit its use to a few times per week.
A diet high in fruits and vegetables may be good for both your body and your teeth.
While they’re no substitute for brushing your teeth, crunchy, raw fruits and vegetables can help rub plaque away as you chew.
In particular, strawberries and pineapple are two fruits that have been claimed to help whiten your teeth.
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 to 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 up a fresh strawberry, combine it with baking soda and brush the mixture on your teeth.
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.
BOTTOM LINE: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.
Your teeth naturally yellow as you age, but there are some things you can do to 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, both of which can cause tooth discoloration.
Limit Sugar in Your Diet
If you want whiter teeth, cut back on your sugar intake.
A diet high in sugar supports the growth of Streptococcus bacteria, the primary type of bacteria that causes plaque and gingivitis
When you do consume a sugary food, brush your teeth soon after you eat.
Get Plenty of Calcium in Your Diet
Some tooth discoloration is caused by enamel eroding away and exposing the dentin underneath, which is yellow in color. Therefore, anything you do to strengthen the enamel of your teeth will help keep your teeth pearly white.such as milk, cheese and broccoli, may help protect your teeth from enamel erosion :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.
While some tooth discoloration comes naturally with age, it is largely a result of plaque build-up.
Regular brushing and flossing can help your teeth stay white by reducing bacteria in your mouth and preventing plaque build-up.
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.
BOTTOM LINE:Daily brushing and flossing, along with regular cleanings at the dentist’s office, prevent the build-up of yellowing plaque on your teeth.
There are a few other natural teeth whitening methods, but there is no scientific evidence to prove that they are effective or safe.
Here are some of the unproven methods:
- Activated charcoal: Brushing with powdered 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.
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.
