What's wrong with gray teeth

Normal people's teeth are not only white, but also slightly yellowish. However, if you find that your teeth do not have these two colors, but instead look a little gray, you should consider that you are using the wrong toothpaste, or you have eaten something recently. If none of these are the case, and the gray color is more serious, you may consider that it is because you often drink coffee, red wine, or some dark colors that have stained your teeth. You need to go to the hospital for regular dental examinations.

Normal people's teeth are a little bit yellowish.

There are many reasons for tooth coloring, which can be divided into roughly endogenous and exogenous in two ways. Exogenous staining is caused by the presence of various bacteria on the surface of teeth, which secrete a lot of sticky substances. Tea stains, cigarette stains in daily diet and certain minerals in drinking water are adsorbed on these sticky substances, gradually turning teeth yellow or black.

Endogenous coloration is formed during the development of teeth. For example, if tetracycline is deposited in the dentin, the teeth will turn yellow, brown or dark gray, which is called tetracycline teeth. If there is too much fluoride in the drinking water, it may also cause fluorosis, and the tooth surface will appear as white chalk or brown patches. If the dental nerve is necrotic and combined with bacterial decomposition products, the teeth may also turn black. When it comes to exogenous tooth staining, coffee, tea, smoking, and red wine are the main culprits. According to statistics, 15% to 25% of Chinese people are smokers, including many female smokers. This means that 200 million to 300 million people in China have yellow or black teeth. The effects of coffee, red wine and tea on teeth cannot be ignored. Teeth whitening is essentially a procedure that removes stains and pigments from the enamel and coating of your teeth. Depending on the depth of tooth color and the cause of formation, different methods should be adopted for whitening.

Effective folk remedy: Use white papaya slices to wipe your teeth twice a day for 2 minutes each time. Do this for a month and it will definitely be effective.

Other Information

Nowadays, more and more people want their teeth to be as white as jade, so many people choose to have their teeth beautified. However, to achieve the best effect, you should choose the appropriate method based on the basic conditions of your own teeth.

First of all, you should understand why your teeth are not white enough. In medicine, simple yellow or dark tooth colors are collectively referred to as tooth discoloration. It is generally divided into two types: exogenous coloration and intrinsic coloration. Simply put, exogenous staining refers to the "external staining" of teeth, which is mainly caused by food pigments, smoke stains, etc. Endogenous staining is caused by taking certain medications or drinking water quality during the period of tooth development, which leads to abnormal tooth color. Common ones include tetracycline staining and fluorosis.
