In the Eastern Han Dynasty Bangu's "Book of Han and The Tale of oriental Shuo", the beauty is described as "like a pearl in the eyes, and the teeth are like a shell", that is, the eyes of the beauty are like pearls, and the teeth are neat and white.
And now, in our communication with people, the neat whitening of teeth has undoubtedly become a very big plus, we often envy the stars on the screen, their teeth are white enough to be neat, but how to brush their teeth can not brush white, today to reveal the secret behind the white teeth.
The first thing to tell you is that healthy teeth are originally yellowish, which is determined by the organization of the teeth themselves, the tooth enamel is transparent, and the dentin is yellow, so the healthier the tooth enamel, the easier it is to penetrate the dentin, so healthy teeth are pale yellow, it is difficult to show cold white
So how do you make your teeth white? Here are a few of the more common methods:
Whitening toothpaste is mostly the addition of silicon substances and low concentration of hydrogen peroxide, used to replace the tooth stain, and then make the teeth white, this process is mostly eliminated is plaque, but because of its own added concentration is very low, the brushing process is very short, so it will not have a particularly obvious tooth whitening effect.
Cleansing powder is mostly added with friction agent, its whitening principle is through the friction agent and tooth enamel to form friction, and then remove part of the plaque, this method of whitening teeth is not recommended to use often, because the friction agent will hurt the tooth enamel on the surface of the tooth to a certain extent, but cause the tooth sensitivity, the effect itself will not be particularly obvious, and it is easy to cause tooth sensitivity, which is not worth the loss.
The main role of scaling teeth is to remove the calculus on the surface of the periodontal periodontal, the effect is to clean the main, to solve the slight periodontal problem, the reason why the teeth will be slightly white after the teeth are washed, because the teeth cleaning removes some of the plaque on the surface of the teeth, which will make the teeth look whiter, and it can only be said that whitening is a small incidental effect of the teeth cleaning, and it cannot really make the teeth directly white.
Cold light whitening refers to the use of silica and other teeth whitening agents on the surface of the teeth, the use of a high-intensity cold light continuous irradiation, through the replacement reaction to make the teeth white, the whole process takes about 30 minutes
Teeth whitening effect is very good, but also the safest and most efficient teeth whitening methods, but cold light whitening is easy to cause tooth sensitivity, teeth after whitening is also easy to be stained, in a short period of time to avoid coffee, tea drinks, soy sauce and other dark foods, want to keep teeth whitening, cold light whitening also need to continue to insist, the price is also very expensive, many people are difficult to afford to consume.
The famous actor Liu Tao once shared his teeth story on Weibo, it is reported that Liu Tao's white and bright teeth are made of cosmetic teeth, that is, grinding their original teeth small, and then making a porcelain braces, putting on the top of the original teeth to form a cosmetic crown.
Such a full mouth redone of a mouth of teeth, can achieve a whitening and neat effect, and permanent whitening without dyeing, but because of the beauty crown, far less than its own teeth are easy to use, and the original good teeth grinding small, only teeth whitening is good to look good is actually not worth the loss.
It is said that Liu Tao's late restoration of a tooth, worth 3 million, many netizens ridiculed, this is to build a house in the mouth, the original teeth are not well protected, really to the time when the teeth are problematic, regret is too late.
In simple terms, the tooth veneer is to stick a layer of material similar to the color of the tooth on the surface of the tooth to achieve the purpose of whitening restoration.
At present, there are only a few methods on the market that can achieve the effect of teeth whitening, but in fact, normally, it is not necessary to do it deliberately for the sake of teeth cold and white.
Normal and standardized brushing, regular visits to the dentist, cleaning intradental stones, and maintaining oral health are the best. After all, dentures are never as good as real teeth, and although pale yellow healthy teeth are not as good as cold white teeth in terms of aesthetics, healthy teeth can really accompany us for a lifetime in terms of use.
