11 Tips to Whiten Naturally Yellow Teeth

Do you have a problem with your teeth? Are your teeth naturally yellow, or they became yellow along the way? Read below to find out why this is the case and what you can do about it.

There are 3 main causes for yellow teeth: physiological, exogenous and endogenous. Bellow we’ll break these down and give you a bit of info.

Physiologically tooth color change

With the increase of age and long-term use, human teeth will gradually have a slight color change. Just like your own skin, when you are young, you are white and lustrous, but when you are older, you gradually become dull. Don’t pay too much attention to this color change. If you care about your appearance, you can use the method of whitening your teeth to improve the appearance, just as you’d do with skin beauty.

Exogenous yellow teeth

Dietary pigments sticking to the teeth are one of top causes of yellow teeth. Beverages, stains caused by smoking, coffee and tea pigments usually cause teeth exogenous stain.

Endogenous yellow teeth

The color of teeth is affected by certain elements. Pigments are not on the tooth surface but in the tooth tissue. There are two main types: fluoride plaque and tetracycline.

Fluorosis mainly caused by living in areas with high fluoride levels in drinking water before the age of seven. The pigment is yellow-brown plaque in the enamel part of the tooth. In severe cases, the tooth surface also has uneven bumps. Generally, the incisors of the upper jaw are more obvious, which seriously affects the aesthetics.

Tetracycline teeth are mainly related to taking tetracyclines before the age of eight. Tetracycline molecules can be combined with calcium in dental tissues to form extremely stable complexes, which are deposited in dental tissues to stain the teeth. All teeth can turn to a brownish gray or brownish yellow.

11 tips to whiten naturally yellow teeth


1. Vinegar:

The vinegar at home (aged vinegar, white vinegar, but not regular vinegar) is contained in the mouth for 1 to 3 minutes, then spit it out and brush your teeth. Although you will have a very sour taste, the effects will make it worth it. This method should not be done continuously, just about once every 2 months. Continuous usage will actually damage the teeth. It can be used as a last resort, for example before going out on a date and you notice your teeth are yellow, and it also eliminates bad breath.

2. Lemon slices:

After brushing your teeth, you can use lemon slices (the lemon juice can also be mixed  in with water) to cover the teeth, which can have a good whitening effect. The principle is that the chemical reaction caused by citric acid will help remove tartar and discoloration.

3. Baking soda and salt:

Take half a spoon of baking soda and salt, add a drop of peppermint or olive oil, and stir to make a natural whitening toothpaste. You can use it to brush your teeth once a week, otherwise it will easily damage the enamel.

4. Drink coffee and add milk:

When drinking tea or coffee, add milk to help change the chemical structure of coffee or tea beverages, and make it more difficult for pigments to adhere to the surface of teeth, and prevent teeth from turning black and yellow.

5. Eat more dark green vegetables:

Spinach, broccoli and other dark green vegetables contain minerals that help to form a protective film on the tooth surface to prevent tooth discoloration. Dental experts also recommend eating more apples, pears, celery, and carrots. Chewing can promote saliva secretion, reduce oral bacteria, and whiten teeth.

6. Rinse mouth for 30 seconds after each meal:

Rinse mouth for 30 seconds after eating, which helps prevent tooth discoloration caused by food pigments, and also removes food residues in the mouth.

7. Drinking with straws:

Drinking carbonated beverages with large mouths can easily damage tooth enamel, causing tooth discoloration and tooth decay. It is recommended to use straws when drinking such beverages.

8. Eat more tropical fruits containing high levels of vitamin C:

Tropical fruits containing high levels of vitamin C can maintain gum health. If you’re lacking these, the gums will become fragile, become more susceptible to diseases, and experience symptoms such as swollen gums, bleeding and loose or missing teeth.

9. Eat more green apples:

If you want to prevent the teeth from turning yellow, the simple and effective way is to brush your teeth after each meal. Experts recommend using green apples with lower sugar content as snacks after meals, which can also achieve the effect of brushing teeth. This is because the rich cellulose and the right amount of fruit acid in the green apple can remove the dirt and make the teeth white.

10.Strawberry tooth whitening paste:

Take a strawberry and 1/2 teaspoon of baking powder. Crush the strawberries into a paste and mix thoroughly with baking powder. Use a soft toothbrush to spread the mixture evenly on the tooth surface. After 5 minutes, brush the mixture with toothpaste and rinse your mouth.

11. Peanuts:

Chew raw peanuts, don’t swallow them. Brushing your teeth with peanuts will start giving your teeth a whitening effect.

How to prevent yellowing of teeth?

Drink plenty of water, rinse your mouth after meals, and keep your teeth clean. It is recommended to use water to rinse your mouth to clean up food residues left in your teeth after meals. Not only does rinsing your mouth clean up food residues, but it also prevents the growth of bacteria and whiten your teeth.

Many foods we use every day are very good for whitening teeth. Foods such as celery, rich in fiber, can secrete more saliva through good chewing. At the same time, chewing fiber can better clean the teeth. Vitamin C-rich fruits such as oranges, bananas, etc., can make the teeth stronger.


Some people like to use toothbrushes that have hard bristles. They believe that this will clean up the teeth more effectively. But if there is too much force applied, it will cause gum bleeding. In winter, this kind of damage to the teeth is particularly serious. Cleaning the teeth too much will damage the natural protective film covering them, so use soft toothbrushes as much as possible to better protect the health of the teeth.

Don’t wash your teeth too frequently at the dentist. Many people take this direct approach to teeth cleaning and whitening, but there are certain hazards that come with frequent tooth washing. Frequent tooth washing will cause the teeth to become larger and larger, allowing food residues and various bacteria to become more easily attached to it. People who often wash their teeth this way will realize that cavities are easier to appear. Therefore, paying more attention to daily dental care is the key to dental health.
