What to do if yellow teeth cannot be washed off

Many people solve the problem of yellow teeth by teeth cleaning, but not everyone sees obvious results or their teeth will slowly turn yellow again after a short period of time. These problems bother us. As everyone's teeth grow, tetracycline will slowly accumulate on the surface of the teeth, so everyone's teeth will gradually turn yellow and need to be cleaned regularly. So what causes teeth to turn yellow? How can we protect ourselves in daily life?

Causes of yellowing teeth

1. Exogenous yellow teeth

The tobacco stains from smoking, the pigments from beverages, coffee, tea, and food etc. adhere to the teeth and appear yellow-gray. Exogenous yellow teeth are mainly caused by lifestyle habits.

2. Endogenous yellow teeth

(1) Fluorosis: This type of dental fluorosis is mainly caused by living in areas with high fluoride content in drinking water before the age of seven. The pigment is in the enamel on the surface of the teeth, appearing as yellow-brown patches. In severe cases, there are uneven defects on the surface of the teeth, which are usually most obvious on the maxillary incisors, thus seriously affecting the appearance.

(2) Tetracycline teeth: This type of teeth is mainly related to the use of tetracycline drugs before the age of eight. Tetracycline molecules can combine with calcium in the tooth tissue to form a very stable complex, which is deposited in the tooth tissue and causes tooth staining, so that all teeth in the mouth may appear brown-gray or brown-yellow.

Intrinsic yellowing of teeth occurs when teeth are formed and is therefore extremely difficult to change.

2. Baking soda: Add a little baking soda to the toothpaste every time you brush your teeth. After brushing a few times, your teeth will gradually become whiter. This method is mainly used for yellow teeth caused by rust.

3. Vinegar: Both white vinegar and aged vinegar are fine. Hold the vinegar in your mouth for 1 to 3 minutes, then spit it out and brush your teeth. One disadvantage is that this method can make your teeth feel numb and sore, so it is not recommended for frequent use unless in an emergency.

4. Using tooth powder Before the advent of toothpaste, tooth powder was the most commonly used teeth cleaner. In ancient times, in order to keep the oral cavity clean and hygienic, people used various tools to brush their teeth and also used various tooth cleaning agents. The most common one was salt, which is the predecessor of tooth powder. In the Song Dynasty, there appeared "tooth powder shops" that specialized in selling tooth powder prepared with traditional Chinese medicine. Tooth powder has become a social commodity. The difference between toothpaste and tooth powder is mainly in form. One is powdery and the other is paste-like. Their main effective ingredients are basically the same.

1. Use salt: Go to the kitchen and get some salt to sprinkle on your teeth before brushing every day (not too much). It is very convenient and easy to use. If you persist in doing so for a long time, you can achieve teeth whitening.

2. Use lemon juice: After brushing your teeth every night, use gauze dipped in some lemon juice to rub your teeth, and their teeth will become white and shiny. Lemon has strong cleaning power and whitening effect. It also contains vitamin C, which can strengthen the roots of teeth. It is a good way to whiten teeth.

The key point of this method is persistence. If you persist every day, you will feel the effect of using orange peel powder to make toothpaste on your teeth.

4. Use vinegar: For people who smoke frequently, the black and yellow smoke stains on their teeth are very distressing. Many people are planning to get rid of these annoying smoke stains one day, but this smoke stain is generally difficult to brush off with toothpaste. In fact, we can use vinegar to brush the smoke stains, which can remove the stains and make the teeth white. The specific method is to take half a mouthful of vinegar, gargle in the mouth for 2-3 minutes, then spit it out, brush your teeth vigorously, and finally rinse with clean water. Repeat several times to remove the smoke stains.
