Coffee is no longer used occasionally to install a [foreign style] prop, but has really become a favorite drink for many people, and its refreshing function also makes many people rely heavily on coffee.
If many people don’t come to a big cup of coffee in the morning, the whole person feels wrong. However, many people can’t love coffee now because they drink too much yellow teeth.
At lunch time, I won’t give rhubarb teeth pictures. I believe you have all seen them.
Why do coffee, tea and red wine dye teeth?
First of all, the enamel on the tooth surface is not as smooth and dense as porcelain. The enamel has numerous tiny pores.
Coffee, tea and red wine, which are famous colored beverages, all contain a substance called tannic acid or tannic acid-[tannin], which is dark brown.
If it acts on the teeth for a long time, it will penetrate into the inside of the teeth, causing coloring of the teeth.
Once this coloring is formed, it is like coffee sprinkled on the carpet. Ordinary cleaning methods, such as brushing teeth and gargling, are difficult to remove the color.
The teeth become a uniform yellow, and with the passage of time, tannin deepens further in the teeth, the saturation of yellow will further increase, the increase of saturation will bring about a decrease in the brightness of the teeth, and the teeth will look less white.
Drinking coffee through a straw?
Therefore, if you want white teeth, it is best to eliminate or reduce the contact between teeth and coffee.
If you can’t drink less, then you can try to use a straw, which is the only magic weapon to prevent all drinks from hurting your teeth. But drinking coffee through a straw is a bit strange, isn’t it?
Milk is the absolute principle.
Is there any way for what to have the best of both worlds?
Of course there is, and it is very simple.
That is milk.
The bricklayer said: [Because milk is white, it has the effect of reducing tooth coloring.] Is that right? Of course not.
Just now it was mentioned that tannic acid plays a big role in tooth coloring. Milk contains casein, which can be combined with tannic acid to reduce free tannic acid, weaken the infiltration of tannic acid into teeth, and greatly weaken the dyeing effect of coffee on teeth.
Therefore, drinking coffee later, adding more milk and calcium can also reduce tooth dyeing.
Cappuccino and Mocha are coffee drinks that contain a lot of milk.
In addition, after drinking colored drinks, it is best to drink some clean water to rinse your mouth, just like cola is stained on the wall. As long as you wipe it in time, there will be no trace of what.
In addition, clear water can also neutralize the acid in the beverage to prevent teeth from being corroded.
What should I do if my teeth are yellow now? Can I wash my teeth?
As I said just now, the dyeing of this kind of teeth goes deep into the interior of the teeth, which is different from the strips of smoke spots on the surface of the teeth. Tooth washing has no what effect.
There are some whitening toothpaste on the market, It has certain effect on the light coloring of teeth. This kind of toothpaste generally contains some low concentration of peroxide or polyphosphate, which can directly act on pigment to whiten teeth again. However, due to safety considerations, the concentration of this effective ingredient in toothpaste will not be very high and the effect will be relatively limited.
If the dyeing is serious or the whiteness of the teeth is high, then you should seek professional help from the dentist. Dentists have various bleaching agents with higher concentrations, which can safely, effectively, comfortably and quickly brighten the teeth again, even whiter than before.
Some people will ask: Foreigners drink more coffee than we do. Why are their teeth so white?
The size of the US tooth whitening market is about 11 billion US dollars a year. Do you understand? š
God created coffee to make people try to change things that can be changed.
It has also created good wine, which makes people readily accept things that cannot be changed.
