As a tea culture lover. I deal with different teas every day. Sometimes tea friends will ask some tea-related questions. For example: “Did I drink too much tea to get yellow teeth”?
Whenever this happens, I always take a sip of tea calmly. Then he showed a row of white teeth, and said earnestly: “My friend, you should smoke less.”
The culprit of yellow teeth
There are many reasons for teeth staining and yellowing. It can be roughly divided into two aspects, namely, endogenous and exogenous. Exogenous coloration is due to dirt in the diet, smoke stains, and certain minerals in drinking water. These sticky substances stick to it and gradually turn the teeth yellow.
Intrinsic coloration is formed during tooth development. Such as tetracycline deposited in the dentin, or too much fluoride in drinking water from childhood. It can turn teeth yellow, brown, or even black.
“Tea” thinks it’s not his fault
Theoretically speaking, the yellowing of teeth after drinking tea is an exogenous cause. If left unattended for a long time, a layer of “tea rust” will accumulate on the surface. Especially in hidden parts that are not easy to clean, such as the lingual and palatal sides of the teeth. However, it is not easy to cause teeth to turn yellow due to drinking tea, unless you are a tea lover who resolutely does not brush your teeth.
Many dental experts believe that some people who drink tea have yellow teeth. In fact, it is caused by smoking while drinking tea, or not brushing teeth cleanly (brushing teeth is a technical job), and not cleaning tartar for a long time. At present, there is no authoritative evidence that drinking tea will cause teeth to turn yellow. Therefore, “tea” feels wronged by the saying “drinking tea will bring out yellow teeth”.
Brush your teeth frequently, check more often
If you want to drink tea so that your teeth don’t turn yellow, the key point is to clean your teeth and mouth carefully. Reduce tooth bacteria from the root. Bacteria is reduced and there is less sticky substance on the tooth surface. The small amount of natural pigment in tea (a drop in the bucket compared to smoke) naturally doesn’t stick to the tooth surface.
Judging from the amount of tea that adults ingest about 10 grams per day for a long time. If you develop the habit of brushing your teeth carefully in the morning and evening and rinsing your mouth after meals, your teeth will never turn yellow.
In addition, drink less strong tea and control the frequency of drinking tea. Try to drink tea made from young leaves. Don’t wait until you have a toothache to see the dentist. Go regularly to clean tartar. These are all effective in preventing teeth from turning yellow after drinking tea.
Healthy teeth start with a cup of tea
There are a lot of tea artists and colleagues who keep drinking every day because of work needs., But they looked not only without yellow teeth, but also red lips and white teeth. This just shows that drinking tea will not affect the yellowing of teeth, but also benefit a lot.
Since ancient times, there have been sayings and records in my country that drinking tea and rinsing the mouth with tea can keep teeth healthy. For example, Su Dongpo, a great writer in the Song Dynasty, once pointed out when he talked about the way of self-cultivation: “I have a method that I think is very valuable to me. Rinse your mouth with strong tea after a meal, not only to get rid of boredom, but also to rinse away the food residues left in the teeth, so as to avoid the trouble of picking teeth. The stronger the teeth are, the closer they will be and prevent tooth decay.”
What he said was that he had a secret recipe, rinsing his mouth with tea after eating every day. Not only can you get rid of boredom, regulate the spleen and stomach, but also avoid the pain of teeth picking. The teeth gradually became firm and tight, and the decayed teeth healed on their own.
After thousands of years of transmission, the wisdom of the ancients has also been confirmed by science. Some experts conducted a preliminary discussion on the anti-caries effect of Pu’er tea through the dynamic observation of the fluoride and tea polyphenol content. The results showed that the water-soluble fluoride in Pu’er tea was 180.72~229.83mg/kg. Drink 4g of Pu’er tea and brew tea soup with a concentration of 0.5%. After 50 minutes, the intake of fluoride reaches the safe and effective anti-caries dose.
In Japan, in order to promote the role of fluoride in tea in preventing caries and strengthening teeth, the activity of “drinking a cup of tea every day” was popularized among children all over the country very early.
In addition, while drinking tea, the water flow in the mouth increases, which can effectively maintain oral hygiene. The sugar, pectin, etc. in the tea react chemically with saliva. It can moisturize the oral cavity and effectively enhance the self-cleaning ability of the oral cavity.
It is also based on this that our common “tea toothpaste” is made of tea extract. It has the functions of antibacterial and anti-inflammatory, preventing dental caries, promoting body fluid and returning sweetness, and decomposing tobacco poison.
Having said so much, I believe all tea lovers should understand. We only need to drink tea in moderation, brush our teeth carefully in the morning and evening, and rinse our mouth after meals. Not only will your teeth not turn yellow, they will be much stronger and there will be less gum disease.
