Although the healthy teeth themselves are a little pale yellow, everyone still prefers white teeth, and a smile reveals white and neat teeth, which is the goal that everyone pursues.
In fact, dentists have a lot of beautiful teeth, bleaching, veneer, can improve the appearance of teeth, but this often requires complicated steps and a lot of money.
So many people started to study the small ways of whitening teeth. When you searched on Google, many people suggested that you use vinegar to clean your teeth. Is this useful? Will it damage the teeth?
Can vinegar or lemon juice whiten your teeth?
First, there are two main reasons for the yellowing of the teeth. One is endogenous coloring and the other is exogenous coloration.
Endogenous coloring is a problem in the interior of the tooth that causes discoloration of the tooth, or the color of the tooth itself is yellow, such as tetracycline. The improvement of endogenous coloring is based on the professional means of dentists and will not be discussed today.
Today’s focus on exogenous coloration is that the exogenous pigment in the diet is attached to the teeth, which means that our teeth are dyed by what we eat and drink, and the teeth are “plated” with a layer of pigment. So long as we can remove this layer of pigment, the teeth will turn white.
Most of the things used in the remedies are things with strong friction, such as soda powder, cuttlefish bone, or some more acidic substances, such as vinegar and various fruits. Although these things can indeed remove this layer of pigment attached to the tooth surface by physical friction or chemical corrosion.
However, they also have a softening or corrosive effect on our teeth.
For example, lemon and vinegar, if you eat some directly, in addition to the tongue feels particularly acidic, the surface of the teeth will also become paralyzed, which is the performance of the teeth received corrosion.
The enamel will soften under the action of acid. At this time, the layer on which the surface of the tooth is softened will easily be rubbed off, usually only a few to ten micrometers thick, but this loss is gone forever. .
Over time, the enamel on the surface of the teeth will become thinner and thinner, and teeth that lack a protective layer will be more likely to fangs. When the nerve endings in the teeth are exposed, the teeth will start to be sensitive, you will start to fear cold or hot food, and the thinning of the enamel will reveal the dentin inside the teeth, and the teeth will be whitened for a short time. It will become more and more yellow, and the purpose of whitening will not be achieved.
Moreover, the raw materials used in these methods are completely unstandardized. The concentration of these “tools” used by all people may be different. In addition, the condition of each person’s teeth is different, and it is impossible to give a safe guide. The safest way is to not use it.
How to properly whiten teeth
The way to properly whiten your teeth is what you do every day: brush your teeth with toothpaste.
Whitening teeth is a big market demand, and manufacturers will certainly not let go. They have developed a lot of black technology to help people remove the exogenous pigments of teeth. Again, the removal of exogenous pigments does not change the color of the teeth themselves.
At this point, some toothpaste manufacturers will also indicate on the toothpaste box, although the words are generally small.
So what kind of toothpaste is whitening toothpaste?
How to choose toothpaste
If you want to choose a true whitening toothpaste, you should ignore the advertising terminology and the effect of the toothpaste box. The key is to see if it contains ingredients that whiten your teeth.
There are two main types of ingredients that can truly achieve whitening: physical friction and chemical adsorption.
The most common types of physical friction are calcium silicate and silica. They all grind natural minerals and use their graininess to remove pigments from the tooth surface. With the aid of these particles, the pigment on the teeth can be removed more efficiently.
This is not the same as the baking soda used in the remedies. The mineral granules used in toothpaste are carefully designed and screened to provide just the right amount of friction to remove pigments without damaging the teeth.
Moreover, the synthetic particles invented by scientists, hydrated silica, is a more advanced abrasive when the performance of natural minerals is still not satisfactory.
Under the premise of good polishing performance, the surface shape of hydrated silica is more rounded, not as sharp as the angular shape of calcium carbonate, and the wear on teeth is smaller.
Therefore, buy toothpaste and pick hydrated silica in the composition table. This effect is better.
The other major category is chemical adsorption. This class is more scientific and technological. Some special chemical components can “smash” the pigment on the teeth, and only the pigments are not damaged.
The main representatives are polyphosphates such as sodium hexametaphosphate, tetrasodium pyrophosphate and the like.
Among them, sodium hexametaphosphate is a relatively good whitening ingredient, which is better than tetrasodium pyrophosphate. You can choose this ingredient when you choose it.
In addition to making the teeth and pigments on the surface easier to separate, these compounds can also competitively bind calcium ions, which have certain effects on the prevention of calculus formation and pigment deposition.
I will tell you a little secret. The ordering of the ingredients on the toothpaste ingredient list is not random, nor is it the order of the sounds or strokes, but is arranged in descending order according to the number of ingredients contained.
That is to say, the content of the material in front of the row is more than that in the back, so if a certain component can play a theoretical role, it ranks higher on the ingredient list. For example, both toothpastes contain hydrated silica, but one is ranked second and one is ranked fifteenth. It can be said that the former is more effective from the perspective of abrasives.
Technology is advancing, toothpaste is not a luxury. I hope everyone can choose the toothpaste and the original teeth. Don’t experiment with your own teeth, because healthy teeth are more precious than diamonds.
