2-year-old baby's teeth are yellow

At about six months, the baby's teeth have already grown. The newly grown teeth are deciduous teeth and are not very mature yet, but the baby can also eat some slightly harder food. After the age of 2, the deciduous teeth are basically fully grown. Newly grown teeth are generally very white, but why do some 2-year-old babies have yellow teeth? Parents should pay attention to whether it is caused by night feeding, and on the other hand, they should also pay attention to oral hygiene.

One is the baby's night feeding

Many babies develop the bad habit of drinking milk at night due to psychological dependence. They will cry and refuse to sleep if they don’t drink milk at night. Many mothers are afraid that their babies will be hungry, and in order to make their babies sleep well, they have to compromise. However, for babies over one year old, drinking milk at night is mostly because they seek psychological comfort. Saliva secretion decreases during sleep, and the food that babies eat is mostly liquid, which easily adheres to the soft tissue mucosa around the mouth. If you don't pay attention to cleaning, it will become a breeding ground for bacteria. Milk stains, food residues and bacteria work together to ferment and produce acid, which accumulates over time and leads to the risk of tooth decay.

Second, neglecting the baby's oral hygiene

Some mothers do not pay attention to their babies' oral hygiene when taking care of them. On the one hand, they think that babies do not have teeth and do not need cleaning; on the other hand, some parents think that babies will change their teeth in the future and it should not affect the growth of permanent teeth. However, if you do not pay attention to cleanliness and hygiene during the period when your baby is growing deciduous teeth, it will also affect the growth of your baby's permanent teeth.

Third, the baby is calcium deficient

If the mother does not take calcium supplements during pregnancy, the baby's tooth enamel may not develop well. Calcium intake affects the structure of tooth enamel, and calcium deficiency can easily lead to incomplete enamel development. When teeth lack the protection of enamel, some common bacteria will take advantage of the situation and firmly adhere to the tooth surface and pits and fissures to form dental plaque, causing children's teeth to turn yellow and black. Not only that, these plaques are also prone to produce a large amount of acidic substances, causing the enamel surface under the plaque to decalcify and dissolve, destroying the dentin.

When you discover that your baby has yellow teeth, timely calcium supplementation can not only strengthen the physique, but also make the permanent teeth that will grow out whiter. If the baby's teeth have already decalcified, timely treatment is needed. In the early stage of decalcification, the ion components in the baby's saliva can be used, or fluoride can be applied to the surface of the baby's teeth to help recalcification. If it is in the later stage, professional treatment by a doctor is required.
