There is a child in my family who has pigmented teeth, and I really want to share the pits I have stepped on and some of the methods I have finally found.
My brother is ten years old this year, and since his baby teeth have grown, small black teeth have begun to appear one after another. At first, I didn't know much about it, and I thought that the child was going to have a large area of tooth decay. However, there were no signs of damage to the structure of his teeth. So, I took him to the dentist. After careful examination by the dentist, I was reassured that there was only pigmentation on my child's teeth. When it comes to this issue, we can first make a comparison with dental caries. Black teeth can also appear in tooth decay, but the biggest difference between tooth decay and pigmentation is that tooth decay is the destruction of the tooth structure, even visible to the naked eye, and the tooth is decayed. Pigmentation is only the coloration of the tooth surface, and does not enter the inside of the tooth body, that is, the structure of the tooth is complete, and we can also see that the pigmentation is only a thin layer of black dyed on the surface of the tooth. 
Add ** note, no more than 140 words (optional) I've thought about this issue carefully as well. After checking the relevant information and comparing the child's eating habits and oral hygiene habits, I found that the following reasons may cause the child's teeth to have pigmentation: Our brother liked sauce foods when he was a child, such as steamed fish drizzled with soy sauce, mixed sauce noodles and the like. He seems to have a soft spot for foods with soy sauce added to them. Of course, some children may like to eat things with dark colors such as cola and chocolate, or take Chinese medicine when they are sick. 
Since I was a child, my brother loved to eat soy sauce noodles, because when I was a child, my brother didn't know how to spit out water and toothpaste foam, so I didn't use toothpaste to help him clean his teeth for a while, but just used water and a toothbrush to brush it simply, and I guess I didn't brush the stains on his teeth. Some children may not brush their teeth properly and do not clean up the stains in time, resulting in pigmentation. In fact, there are still relatively few people around me who have pigmentation on their teeth like our children. And even if their snacking habits are more exaggerated than his, and they are less serious when brushing their teeth, these children will not have little black teeth. A dentist told me that it may be related to each child's constitution, the composition and metabolism of different microorganisms in the mouth. 
Add ** note, no more than 140 words (optional)Compared with tooth decay, the pigmentation of teeth has the greatest impact on the child's aesthetics. I remember when my brother was a child, as soon as the seven aunts and eight aunts got together, chatting and chatting, the focus would run to the children's teeth, and then we would use our brother's little black teeth as a negative example to teach our children to brush their teeth well and eat less snacks, otherwise they will become little black teeth. On such occasions, my brother would be very embarrassed, and he would say to me in distress how to turn his teeth white, and he really hated people always talking about his little black teeth.
So, I took him to get his teeth cleaned. The dentist used a slow rotation polishing method to remove the dark spots on his teeth, and after washing, the small black teeth did indeed turn into small white teeth. 
However, scaling is not a symptomatic cure for tooth pigmentation. After a while, I noticed that some pigmentation slowly appeared on his teeth again. And, as he grew older, he became more and more concerned about his appearance. So, I started to think of new ways to find a way to prevent and solve tooth pigmentation, until a while ago I came across Ole V Kids Dental Protector.
After two weeks of trial, the pigmentation on the child's front teeth was partially removed, and the child and I are quite satisfied with the results. 
The effect after two weeks of continuous useThis toothpaste is different from ordinary toothpastes on the market, and the special thing about this toothpaste is that it has a patented technology, patented ingredient potassium calcium phosphosilicate. When brushing your teeth with Aole V Dental Protector, it works with glycerin to adsorb, disintegrate and remove tooth stains, and brush away exogenous black and yellow teeth. My children have a deep understanding of this after using it, watching the dark spots on the teeth be brushed off little by little every day, and we feel that we are no longer helpless about the pigmentation on the teeth. The child said that as long as we insist on brushing our teeth properly with Ole V Children's Dental Protector, sooner or later we will remove all the dark spots in his teeth. 
The paste is light blue and the taste is fruity, as we have summarized before, my child's tooth pigmentation may be related to his oral microbes. This Aole V children's dental care agent can also improve the child's oral environment to be weakly alkaline, which can inhibit oral pathogenic bacteria, make a variety of cariogenic bacteria quickly inactive, and inhibit the occurrence or deterioration of tooth decay. The best thing about this toothpaste is that it contains the patented ingredient potassium calcium phosphosilicate, which releases silicon, calcium, phosphorus and potassium ions when brushing your teeth with Ole V Dental Care, which are the same minerals for teeth, which can help children repair and strengthen tooth enamel, and prevent bacteria from causing acid to corrode teeth. This, in turn, can help your child prevent tooth decay.
In addition, the effectiveness and safety of this toothpaste have also been clinically verified by the authoritative tertiary hospitals of West China School of Stomatology and Wuhan University School of Stomatology. For mothers like me who have no professional oral knowledge, I trust products with reliable third-party endorsement when choosing children's toothpaste, and the quality is ***
Add ** note, no more than 140 words (optional) This toothpaste has zero added SLS, preservatives, flavors, saccharin sodium, and the taste is fruity. The first time my brother used it, he said he liked the flavor, and he has been using it for two weeks now, and he plans to continue using it in the future. Compared to having to go to the dental hospital if there is a little problem with the teeth, it is not only difficult but also expensive, and some oral problems can be solved by brushing teeth with Aole V tooth care agent, and the child is as happy and excited as if he has found a savior. Your child may already have pulpitis, so be sure to take your child to the dentist right away, and then stick to Ole V Dental Protector to protect other healthy teeth and prevent them from becoming decaying. If your child's tooth decay has deteriorated to the stage of medium caries or deep caries, you can also take your child to the dentist**, and then insist on using Orle V dental care to form useful substances on the surface of the teeth, which can relieve the child's tooth sensitivity and relieve toothache. 
Add ** note, no more than 140 words (optional) The child's teeth have shallow decay. In this case, consistent use of Ole V Dental Protector can stop the tooth decay from progressing. This is the situation that parents like to see the most, if the child can insist on using Ole V Dental Protector at least once a day before going to bed, it can not only help the child clean the food residue in the mouth, but also improve the oral environment to weak alkaline, escorting the child's oral health.
Finally, I hope that all children can have good teeth, good appetite and good health
