A friend sent a photo of the baby and said: Found that the child's teeth have small white spots, is it the kind of graying without luster, is it normal? Is it caries? Usually, I also pay attention to how can I still have bad teeth when I brush my teeth?
The appearance of white spots on the surface of your baby's teeth that cannot be scraped off is generally a manifestation of tooth demineration, that is, the loss of minerals on the teeth.
The most significant feature of tooth demineration is that the tooth surface is rough, the color changes, and the white or yellowish spots appear, but this white is different from the white of healthy teeth, dull and dull, as long as it is compared with other healthy teeth.
Under normal circumstances, the tooth is in a balanced state of "demineration-reminalization", maintaining its hardness. For example, only when the pool water intake and output water are balanced, the pool can maintain a normal water level. The same goes for teeth.
For healthy teeth, although there will be bacteria and acidic substances in the mouth that continuously dissolve the calcium and phosphorus ions on the surface of the teeth, that is, the teeth are deminerated, the calcium and phosphorus ions in the saliva will continue to be deposited on the tooth surface, that is, remineralization. As long as these two processes are balanced, tooth enamel will not have the problem of demineration.
But when eating sour, sweet food, the bacteria in the mouth will use the sugar in the food to ferment acid, resulting in the oral environment is acidic, when these bacteria produce acid to a certain extent, it will break the normal "demineration - remineralization" balance of the teeth, the hardness of the tooth enamel will gradually decrease, and then demineration will occur, without intervention, it is easy to develop into caries.
That is, tooth enamel demineration is the smallest carious state visible to the naked eye and is a precursor to caries.
In addition to caries, the following 3 conditions can also cause white spots on your baby's teeth.
1. Tooth enamel hypoplasia
Enamel hypoplasia is a common disease of tooth structure abnormalities. It generally refers to the abnormality of the enamel structure of the tooth due to severe trophic disorders, endocrine disorders, severe apical periodontitis of deciduous teeth and other infections during development.
Because the enamel development is not all defects left during development, so the inflammation of the deciduous teeth must be treated in time, do not think that the deciduous teeth will be replaced by permanent teeth sooner or later, and do not pay attention to the disease of the deciduous teeth, which is very wrong.
2. Dental fluorosis
Dental fluorosis, also known as spot glaze, is often associated with excessive levels of fluoride in the water or soil of the area.
If your baby ingests too much fluoride during tooth development, chalky plaques will appear on the surface of the teeth, and then gradually turn brown, and in severe cases, the teeth will also be defective, and the tolerance to friction is poor.
Some mothers ask: The baby is 2 years old, if you use fluoride children's toothpaste, does it have an impact on swallowing? Is it impossible to choose fluoride toothpaste?
The fluoride content standard of children's toothpaste in mainland China is: 0.05% to 0.11%. In the case of a 6-year-old child of about 20 kg, more than 200 g of toothpaste is swallowed to reach a toxic dose.
Therefore, mothers should not postpone the baby's brushing date because the baby will not spit out toothpaste and mouthwash; and do not worry about the baby's fluorosis and dare not choose fluoride toothpaste.
According to guidelines from the American Dental Association ADA and the American Pediatric Association AAP: After your baby has grown their first teeth, you should brush your teeth with fluoride toothpaste.
It is recommended that children under 3 years of age use no more than the size of a grain of rice per use (lightly apply a thin layer to a toothbrush), and children over 3 years of age should use no more than the size of a pea per use.
3. Dental calculus
When the milky white dirt remains on the teeth for a long time, it will gradually calcifie and harden over time, forming early dental calculus, but it can be scraped off with force.
Some people ask: How to judge which situation is specific?
Found abnormal, generally not recommended self-diagnosis autonomous, it is best to let the dentist to see.
In order to better protect the teeth, it is recommended that from the age of 1, parents should regularly take the baby to the dentist. The Chinese Society of Stomatology recommends that children should have an oral examination every 3 months to six months. Generally, the development of the jaw bone and the number, size, arrangement, appearance, etc. of tooth growth are normal.
Caring for teeth is a lifelong project, even if it is deciduous teeth, we must do a good job of cleaning and protection, we must take it seriously
