Changes in the color of your teeth may be something that happen gradually. Some yellow color may be inevitable.

Teeth can look more yellow especially as you grow older. As the outer enamel wears away, the yellowy dentin underneath becomes more visible. Dentin is the calcified tissue beneath the enamel. 

If you’re looking for easy way to whiten your teeth, you do have some easy alternatives here.

Home Remedies to Treat Yellow or Brown Teeth.

Here are five easy natural options for getting rid of yellow teeth. It may be best to choose a few treatments and rotate them throughout the week. Experiment to find a solution that works for you.
1. Brushing your teeth.
Your first plan of action should be to brush your teeth more often and in the correct manner. It’s especially important that you brush after consuming foods and drinks that can lead to yellow teeth.
Brush your teeth at least twice a day for two to three minutes at a time. Make sure you get into all of the cracks and crevices. Brush your teeth in a circular motion to ensure you’re protecting your gums. Brush the inside, outside, and chewing surfaces of your teeth.

2. Baking soda and hydrogen .                       

 Using a paste made of baking soda and hydrogen peroxide is said to remove plaque buildup and bacteria to get rid of stains.

Mix 1 tablespoon of 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 mouthwas

A 2012 study found that people who used a toothpaste containing baking soda and peroxide got rid of tooth stains and whitened their teeth. They showed significant improvements after six weeks. Further studies are needed to determine if the results persist after they stop using the toothpaste.
3. Lemon, orange, or banana peels.
Some people claim that rubbing lemon, orange, or banana peels on your teeth will make them whiter. It’s believed that the compound d-limonene, which is found in some fruit peels, will help to white your teeth.
Gently rub the fruit peels on your teeth for about two minutes. Make sure to thoroughly rinse out your mouth and brush your teeth afterward.          
Scientific research proving the effectiveness of using fruit peels to make teeth whiter is lacking. However, a study from 2010 looked at the effect of a toothpaste containing 5 percent d-limon in removing stains from smoking and tea. People who brushed with a toothpaste containing d-limonene combined with a whitening formula twice daily for four weeks significantly reduced smoking stains, though it didn’t remove long-standing smoking stains or tea stains.
Further studies are needed to determine if d-limon is effective on its own.
A study from 2017 tested the potential of citric acid extracts from four different types of orange peel as a teeth whitener. They were shown to have varying abilities on whitening teeth, with tangerine peel extract achieving the best results

4. Eating fruits and vegetables with a higher water content.
It’s said that eating raw fruits and vegetables with a high-water content can help to keep your teeth healthy. The water content is thought to cleanse your teeth and gums of plaque and bacteria that lead to yellow teeth.
Eating crunchy fruits and vegetables at the end of a meal may increase saliva production. This can help to remove food particles that are stuck in your teeth.
While there’s no doubt that a diet high in fruits and vegetables is good for your dental and overall health, there’s not a lot of scientific evidence that supports these claims. That said, eating these healthy foods throughout the day or at the end of a meal certainly won’t do any harm.
Specific scientific studies are needed to confirm these claims. One study showed that using a baking soda and strawberry mix wasn’t effective in whitening teeth.
Research from 2007 found that vitamin C deficiency can increase the severity of periodontitis. While the study didn’t look at the whitening effect of vitamin C on teeth, it links high-plasma vitamin C levels to healthy teeth. The research suggests that high levels of vitamin C can reduce the amount of plaque that causes teeth to become yellow.
A study from 2012 found that a toothpaste containing papain and bromelain extract showed significant stain removal. Papain is an enzyme found in papaya. Bromelain is an enzyme present in pineapple.
Further studies are warranted to expand upon these findings.
4. Activated charcoal.
You can use activated charcoal to remove stains from your teeth. It’s highly absorbent and is also said to get rid of bacteria and toxins in the mouth.
Open a capsule of activated charcoal and put the contents on your toothbrush. Gently brush your teeth using small circles for two minutes. Be especially careful in the area around your gums as it 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 on for two minutes.
You can also mix activated charcoal with a small amount of water to make a mouthwash. Swish this solution for two minutes, and then spit it out. Rinse your mouth thoroughly with water after using activated charcoal.
More scientific evidence is required to investigate the effectiveness of activated charcoal in teeth whitening.Research from 2015 found that activated charcoal was more abrasive than a whitening toothpaste on dental acrylic resins.

The researchers didn’t conclude that activated charcoal isn’t suitable for teeth whitening. Its absorbent nature has the potential to remove stains. However, it should be noted that charcoal powder could become embedded in margins or cracks that are especially present in older teeth.

5.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 6 ounces of water. Swish the solution for 30 seconds. Then rinse with water and brush your teeth.
Research from 2014 found that apple vinegar has a bleaching effect on cow teeth. However, it should be noted that it has the potential to cause damage to the hardness and surface configuration of teeth. So use it with caution, and only for short amounts of time. More human studies are needed to expand upon these findings.

Conclusion

Continue to practice good oral hygiene and have regular dental checkups.

If you’ve tried these methods without success, your dentist may be able to help you determine if another course of action will be best for you.
