Why are baby teeth yellow?

Many babies will start to grow teeth when they reach a certain age. Under normal circumstances, the teeth that grow out are relatively white. Some babies will have the problem of yellowing teeth, which makes many parents very worried. If your baby's teeth turn yellow, you must pay attention to it. Many reasons may cause this phenomenon, and it is likely that there is a problem with the child's health. So what is going on with your baby's teeth turning yellow?

1. Health factors:

If the baby's teeth are not properly nourished or have been ill during their development, their calcification may be affected, and the teeth may become yellow and brittle.

2. Water quality factors:

In some areas, especially in some mountainous areas, due to the high fluoride content in the water, drinking too much fluoride will cause the teeth to turn yellow. And it is not just 1-2 teeth, but a whole mouth of yellow teeth. Fluoride has an anti-caries effect, so these people are less likely to develop caries.

3. Drug factors:

Now most people know that tetracycline drugs can cause yellow teeth, especially when taken by children (before 5 years old).

4. Hygiene habits:

Food residues left in the mouth will mix with bacteria to form a thin film that adheres to the teeth, forming dental plaque. After staying in the mouth for a long time, it will decalcify the teeth and slowly cause tooth decay. Newborns do not have this bacteria in their mouths and it is usually passed to babies through the saliva of their mothers or caregivers. In addition, breast milk or formula milk contains lactose. If children often sleep with a bottle in their mouths or have the habit of drinking milk at night, it may cause tooth decay.
