Throughout the ages, people have taken great pains to pursue a white tooth.
As early as 4,000 years ago, ancient Egyptians began to whiten their teeth. They mixed pumice powder with white vinegar to make whitening agents.
In ancient Romans, urine was used to whiten teeth!
Yes, you are right. Because the ingredient in urine [ammonia] is a bleach.
In modern civilized society, although these absurd methods will not be used, human beings’ pursuit of dental beauty has never stopped.
Don’t try these unreliable whitening methods again.
Nowadays, there are many unreliable tooth whitening methods on the market.
Some people use whitening mouthwash, but if they really want to achieve whitening effect, they are very testing the technology.
Although mouthwash contains the correct bleaching ingredients, the bleach needs to be in close and correct contact with the tooth surface for several minutes or more before it can work.
Whitening tooth patch is also a common method used by many people, but there are also safety risks.
The active ingredient usually covered on the surface of these dental patches is [hydrogen peroxide].
However, because these dental patches are not customized according to personal circumstances, hydrogen peroxide may contact other tissues such as gums or oral mucosa during use, causing gingivitis or oral mucosal diseases.
The so-called ultraviolet light, LED and laser whitening are not recommended either.
Studies have shown that these lights have no effect on tooth whitening [1] and may even cause damage to dental nerve [2].
In fact, instead of spending money and energy on whitening teeth, it is easier and more practical to think about how not to make teeth yellow.
After all, the teeth are not yellow, they turn yellow only when they are not used correctly.
Pay more attention to [colored food]
We tend to have a big appetite when faced with colorful food.
However, it is often these colored foods that leave pigment on our teeth, such as dark foods such as coffee, cola and red wine.
Bacterial secretion and sticky substances formed by themselves exist on the tooth surface, which will further promote pigment to adhere to the tooth surface and accumulate over time, making the tooth surface gradually turn yellow or black.
The most common food causing tooth coloring:
1. Coffee and tea. The tannic acid they contain is the main cause of tooth coloring.
2. Red wine.
3. Soda, such as cola. The dark color of cola itself works with the acid in it to turn teeth yellow.
4. Juice. Especially dark juice, such as blueberry juice and grape juice.
5. Soy sauce.
6. Ketchup/Juice.
7. Curry.
8. Blueberries.
What should I do?
Rinse your mouth after eating.
Rinsing your mouth in time after eating and drinking is helpful to remove food residues and beverage residues from your teeth and reduce their damage to your teeth.
Smoking not only hurts the lungs, but also hurts the teeth
If you look closely, you will find that long-term smokers generally have yellow and black teeth.
This is because the surface of our teeth is not completely flat and smooth, but there are many micropores, just like sponges.
When smoking, nicotine and tar in tobacco are easily absorbed into these micropores, causing teeth to turn yellow.

In the long run, it is also easy to cause halitosis and other more serious oral problems.
For the sake of image, quit smoking.
The way you brush your teeth may be wrong.
Many people brush their teeth every day, but there are still oral problems.
The main reason is that the brushing method is wrong, the cleaning is not in place, and the brushing is also white…
Babbitt brushing is a recommended brushing method for every dentist, and it is also an effective brushing method for cleaning the interior of the oral cavity.
There are roughly three main points of Babbitt brushing method:
- The toothbrush is tilted 45 degrees towards the gums, placed at the junction of the teeth and gums, and trembles gently. Brush your teeth twice a day for at least 2 minutes each time. Brush every tooth surface, and finally don’t forget to brush your tongue.
Proper use of Babbitt brushing can keep teeth clean and beautiful.
