The color changes in your teeth can be subtle and occur gradually. Some yellow color may be unavoidable.
Teeth may look more yellow, especially as they get older. As the outer enamel wears out, the yellowish dentin underneath becomes more visible. Dentin is the calcified tissue beneath the enamel.
If you want to whiten your teeth, you have alternatives to conventional methods.
Remedies for yellow teeth
Here are seven natural options for getting rid of yellow teeth. It may be better to choose a few treatments and alternate them throughout the week. Experiment to find a solution that works for you.
1. To brush your teeth
Your first course of action should be to brush your teeth more often and in the right way. It is especially important that you brush your teeth after eating foods and drinks that can cause yellow teeth.
Brush your teeth at least twice a day for two to three minutes at a time. Make sure to enter all cracks and crevices. Brush your teeth in circular motions to make sure your gums are protected. Brush inside, outside and nibbling surfaces of your teeth.
2. Baking soda and hydrogen peroxide
Using a paste of baking soda and hydrogen peroxide, it is said that it eliminates plaque build-up and bacteria to remove stains.
Mix 1 tablespoon baking soda with 2 tablespoons of hydrogen peroxide to make a paste. Rinse your mouth thoroughly with water after brushing with this paste. You can also use the same ratio of ingredients to make a mouthwash.
3. Extraction of coconut oil
It is said that drawing coconut oil removes plaque and bacteria from the mouth, which helps to whiten teeth. Always use a high quality organic oil that does not contain any harmful ingredients.
Swish 1 to 2 teaspoons of liquid coconut oil in the mouth for 10 to 30 minutes. Do not let the oil touch the back of your throat. Do not swallow the oil as it contains toxins and bacteria from your mouth. Spit it in the toilet or in a wastebasket because it could clog the drains. Rinse your mouth with water and drink a large glass of water. Then brush your teeth.
No specific study has confirmed the whitening effect of the teeth resulting from the extraction of the oil. However, a 2015 study found that extraction of sesame oil and sunflower oil reduced gingivitis caused by plaque. Pulling oil may have a whitening effect on the teeth, as plaque buildup can yellow teeth. Further studies on the effects of oil extraction with coconut oil are needed.
4. 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 6 ounces of water. Swish the solution for 30 seconds. Then rinse with water and brush your teeth.
Research conducted in 2014 showed that apple vinegar had a whitening effect on cow teeth. However, it should be noted that it can potentially damage the hardness and configuration of the tooth surface. So use it with caution, and only for short periods. More human studies are needed to develop these results.
5. Peel of lemon, orange or banana
Some people claim that rubbing lemon, orange or banana peels on their teeth will make them whiter. It is thought that the d-limonene compound found in some fruit barks will help whiten teeth.
Gently rub the fruit peels on your teeth for about two minutes. Make sure you rinse your mouth and brush your teeth afterwards.
Scientific research proving the effectiveness of using fruit barks to whiten teeth is lacking. However, a 2010 study investigated the effect of a toothpaste containing 5% d-limonene on the removal of tobacco and tea stains. People who brushed d-limonene-containing toothpaste with a whitening formula twice a day for four weeks significantly reduced tobacco stains, but did not eliminate the lingering stains associated with tobacco or tea.
Further studies are needed to determine if d-limonene is effective as such.
6. Activated carbon
You can use activated charcoal to remove stains from your teeth. It is very absorbent and also removes bacteria and toxins in the mouth.
Open an activated carbon capsule and put the contents on your toothbrush. Brush your teeth gently using small circles for two minutes. Be especially careful around your gums, as this can be abrasive. Then spit it out.
If your teeth are sensitive or you want to limit the abrasiveness of the charcoal, you can dab it on your teeth. Leave it for two minutes.
You can also mix active charcoal with a small amount of water to form a mouthwash. Swish this solution for two minutes and then spit it out. Rinse your mouth thoroughly with water after using activated charcoal.
Additional scientific evidence is needed to study the effectiveness of activated carbon in teeth whitening. Research conducted in 2015 showed that activated carbon was more abrasive than toothpaste whitening on dental acrylic resins. The researchers did not conclude that activated charcoal is not suitable for teeth whitening. Its absorbent nature has the potential to eliminate stains. However, it should be noted that charcoal powder may become embedded in margins or cracks, especially in older teeth.
7. Eat fruits and vegetables rich in water

It is said that eating raw fruits and vegetables rich in water can help you keep your teeth healthy. It is thought that the water content cleans your teeth and gums from plaque and bacteria that cause yellow teeth.
Eating crunchy fruits and vegetables at the end of a meal can increase saliva production. This can help remove food particles stuck in the teeth.
Although a diet rich in fruits and vegetables is beneficial to your dental health and your overall health, there is not much scientific evidence to support these claims. That said, eating healthy foods throughout the day or at the end of a meal will certainly do no harm.
Specific scientific studies are needed to confirm these claims. A study has shown that the use of a mixture of baking soda and strawberries was not effective for whitening teeth.
Research conducted in 2007 showed that vitamin C deficiency can increase the severity of periodontitis. The study did not examine the whitening effect of vitamin C on teeth, but it does link the high plasma levels of vitamin C with healthy teeth. Research suggests that high levels of vitamin C can reduce the amount of plaque that causes yellowing of teeth.
What causes yellow teeth?
Many factors can cause yellowing of the teeth. Teeth can turn yellow from:
some foods or drinks, such as blueberries, red wine, coffee or tea
a diet rich in sugar and simple carbohydrates
smoking or chewing tobacco
Side effects of some medications and mouthwashes
age, because older adults are more likely to have yellow teeth
excessive use of fluoride
bad dental care and oral hygiene
dry mouth or lack of chronic saliva
The bottom line
Continue to practice good oral hygiene and have regular dental checkups. If you have tried these methods without success, your dentist may be able to help you determine if another course of action is right for you.
