Tetracyclines.

Tetracyclines can cause teeth to turn yellow and black. Usually, pregnant and lactating women and babies under eight years old may have tetracycline teeth after using tetracycline drugs, especially before the baby is 5 years old.

Water with excessive fluorine content.

The development and mineralization of permanent teeth are completed before 6-7 years old. It is most appropriate to keep the fluorine content in drinking water within 0.5- 1ppm, which can prevent caries and chronic fluorosis. If you drink water with high fluorine content for a long time during tooth development and mineralization, it will cause macular teeth (medically called dental fluorosis or dental fluorosis) and even lead to chronic fluorosis.

Sweets, carbonated drinks.

Candy and sticky sweets are easy to adhere to the surface of teeth and between teeth, which can ferment and produce acid and form dental caries. Carbonated drinks are also easy to cause tooth decay and affect appetite, so avoid eating snacks or sweets before eating, especially before going to bed.

Baby teething to eat:

2-tooth period

Generally, when the baby is 4-8 months old, the front teeth in a pair of breasts in the lower jaw quietly erupt, and the baby has since left the ranks of toothless. Babies in this period like to chew up everything they can get into their mouths, which makes people laugh and cry. Sometimes they even imitate the actions of adults chewing chopsticks and spoons.

In the meantime, the mother can try to give her baby some semi-solid food, such as mashed potatoes, egg yolk, porridge, etc., so that the baby can experience the transition from a watery diet to a pasty diet. A slightly thicker complementary food can make the baby realize that his food has begun to change, laying the foundation for adding solid food for the baby to exercise and chew with his teeth in the future.

Four-tooth period

About 8~ 12 months, the baby's upper jaw will grow more than two teeth. At this time, the baby's nutritional needs are getting higher and higher. In the meantime, mothers should give their babies more choices, such as minced meat, minced meat, tomatoes, tofu and so on.

However, if the baby's chewing ability is not good, the baby's digestive function is weak, and the block food does not enter the digestive system after being crushed by teeth, and the nutrients are not easy to decompose and utilize. Therefore, parents should consciously guide their babies to practice chewing with solid food during this period.

6~8 tooth period

Maxillary lateral incisors will erupt in 9~ 13 months, and mandibular lateral incisors will erupt in 10~ 16 months. During this period, the baby began to slowly adapt to solid food, and the digestive function of the stomach gradually matured.

In the meantime, mothers can give their babies solid food, such as steamed eggs and vegetables.

8~ 12 teeth

About 13~ 19 months, the baby will sprout the first deciduous molar (big tooth).

With deciduous teeth, the baby's chewing ability is greatly improved. During this period, the baby will enthusiastically send food to his mouth with a spoon, even if he eats all over the table, it is worthy of his mother's encouragement, which will also have an impact on his future personality.

This period can reduce the intake of liquid food and increase solid food, such as soft rice, bread, vegetables and sliced meat.

12~20 tooth period

During the period of 16 to 20 months, the baby's 20 deciduous teeth gradually grew together, completing the whole eruption process of deciduous teeth series. During this period, the baby can not only swallow food by himself, but also improve his feeding skills. The mother can give ordinary soft food, such as rice, noodles and soybeans.
