The discoloration of the teeth may be subtle and occurs gradually and usually turns yellow in color. Teeth can appear yellower or darker especially with age.
As the outer enamel wears off, the yellow dentin will become more visible. Dentin is an intermediate between the enamel (the substance in the crown) or cement (the substance in the root) of the tooth and the pulp chamber.
If you want to whiten your teeth, there are several alternatives to conventional methods. Please be careful when doing the bleaching process at home. Some products can damage teeth if used incorrectly or for too long.

1. Brushing teeth
Brush your teeth more often and the right way. It is very important to brush your teeth after consuming foods and drinks that can cause yellow teeth.
Brush your teeth at least twice a day for two minutes. Make sure to reach all the crevices of the teeth. Use gentle circular motions so as not to damage the gums. Brush the inside, outside and the chewing area.
According to a 2018 study, brushing with whitening toothpaste has been scientifically proven to whiten teeth.
This whitening toothpaste contains mild abrasives to gently and safely remove surface stains. If you have an electric toothbrush, it is equally effective at removing surface stains.
2. Using baking soda powder and hydrogen peroxide
Using a toothpaste made of baking soda and hydrogen peroxide can remove the buildup of plaque, bacteria, and dirt.
Mix one tablespoon baking soda powder with two tablespoons of hydrogen peroxide to make a toothpaste. Gargle your mouth with water after brushing with these ingredients.
Baking soda powder and hydrogen peroxide can be obtained online at e-commerce. A 2012 study found that people who used a toothpaste containing baking soda powder and peroxide, the stains on their teeth disappeared and were significantly whiter after 6 weeks of use.
A 2017 review of toothpaste research with baking soda powder, also concluded that these ingredients are effective and safe to use every day to remove stains and whiten teeth.

3. Use apple cider vinegar
Apple cider vinegar can be used in very small amounts to whiten teeth. Make a mouthwash by mixing 2 teaspoons of apple cider vinegar with 28 ml of water.
Clean your teeth with the liquid for 30 seconds. Then rinse with water and brush your teeth. Research published in 2014 found that apple cider vinegar has a whitening effect on cows’ teeth.
However, it should be noted that apple cider vinegar has the potential to affect the hardness and structure of the tooth surface.
So, use it with care and only use it for a short time. More human studies are needed to expand on these findings.
4. Lemon, orange, or banana peel
Some people claim that rubbing lemon, orange, or banana peels on their teeth will make them whiter.
It is believed that the citric acid compound found in citrus fruit peels can help whiten teeth.
Rub the skin of the fruit gently for 2 minutes. Be sure to rinse your mouth thoroughly beforehand and brush your teeth afterward.
Not too many scientific studies have proven the effectiveness of using fruit peels to make teeth whiter.
However, a 2010 study on the effects of toothpaste containing 5 percent citric acid, showed that the toothpaste was able to remove tooth stains caused by smoking and tea.
People who brushed their teeth with a toothpaste containing citric acid combined with a whitening formula twice daily for 4 weeks, significantly reduced smoking stains.
A 2017 study tested the potential of citric acid extract from four types of orange peel as a teeth whitener. They are proven to have various abilities on teeth whitening.
ETangerine peel extract achieved the best results in this test. Be careful when using this strategy. Acid can erode and weaken tooth enamel. If in doing this method your teeth become more sensitive, stop immediately.
Those are 4 simple ways to whiten teeth, to get the best results, do it regularly at home.
