Brush so long tooth, why still yellow?
Have you ever looked at a toothpaste AD on TV and wondered why the model’s teeth were so white?
I brush my teeth carefully all the time. I bought the toothpaste with whitening effect in the advertisement. How can I not see white?
Learning Xiaobian decided to go to the bottom of the mystery, to solve the teeth yellow ~ yellow teeth is unhealthy?
In fact, normal teeth are translucent and pale yellow, also known as ivory.
This is because the inner layer of tooth enamel is dentin, which has a composition similar to bone and is yellowish in color.
Teeth calcify with age, so adult tooth enamel is translucent.
Therefore, the color of dentin through tooth enamel, slightly transparent light yellow is normal healthy color.
Why are teeth more and more yellow?
Teeth tend to turn yellow or dark as we age, and some people have yellowish teeth.
In fact, there are two main causes of tooth yellowing: exogenous and endogenous.
Exogenous: mainly caused by some lifestyle and habits.
The enamel on the tooth surface is covered with tiny holes.
Usually drinking tea, coffee, cola, red wine, colored drinks, eating curry and other pigmented food, the use of colored toothpaste, mouthwash, smoking, etc., will make pigmentation, teeth inevitably stained with color.
Endogenous: 1. Water quality in some areas, especially in mountainous areas, the water used by people contains a large amount of fluorine. Long-term drinking causes teeth to turn yellow and appear yellowish-brown patches, which is dental fluorosis.
There are even defects that cause uneven surfaces.
However, fluoride has an anti-carious effect, so these people are less likely to develop cavities.
2, the most typical drug is tetracycline teeth.
This has to do with the tetracycline antibiotics.
Children who take tetracycline antibiotics have the greatest impact.
Tetracycline drugs are very affinity for teeth and other calcified tissues, which are easy to bind with calcium and form very stable chelates deposited in the tooth tissues, making the teeth color grayish-brown or yellow-brown, and even affecting the incomplete development of tooth enamel.
3. Tooth nerve necrosis Tooth nerve necrosis, if once combined with bacterial decomposition, teeth may turn yellow and black.
4. Heredity causes yellowing of the teeth themselves.
Malnutrition during tooth development can also cause teeth to turn yellow and loose.
Many people have the misconception that teeth will turn white after cleaning.
In fact, cleaning teeth is just cleaning teeth.
Teeth cleaning is the use of ultrasonic vibration principle, will not belong to the teeth themselves to shake off things, such as tartar, smoke stains, tea stains, dental stones…
Not much tooth whitening.
2, porcelain teeth to grind a small circle of teeth, and then set porcelain teeth, like putting on a piece of clothing for teeth.
In fact, many celebrities are made of a mouthful of white teeth.
Porcelain teeth are an option for severe fluorosis or tetracycline teeth.
Generally healthy teeth are not recommended, because porcelain teeth cost more, use only 10 years, and irreversible, once started, lifelong companion.
3, cold light whitening using high intensity blue light, through optical fiber conduction, after special optical lens optical treatment, with hydrogen peroxide and silica whitening agent, so that the teeth produce REDOX reaction, to achieve the whitening effect.
May appear soreness and other discomfort, and can only maintain half a year to two years, the price is relatively high.
Think twice before you make a decision.
Do not smoke, drink less tea, coffee and other drinks.
2. Gargle after meals.
3. Brush your teeth correctly in the morning and evening.
4. Floss properly.
5. Visit your dentist regularly for a cleaning.
Finally advise everyone: take good care of your teeth, less toss!
