What is the reason for the 2-year-old baby's black teeth?

The two-year-old baby's black teeth are usually caused by poor cleaning or tooth decay. If children usually eat dark food in complementary foods, or like to eat snacks such as chocolate, but children don't like to brush their teeth, these food residues will remain on their teeth, making them look black. In this case, parents should urge their children to brush their teeth in the morning and evening, do a good job in oral hygiene and cleaning, and usually eat less food with more pigments. The 2-year-old baby's teeth are black, and another situation is caused by tooth decay. Tooth decay looks like black patches or yellowish brown patches. Children don't like brushing their teeth because there are many kinds of food. Poor oral hygiene can breed bacteria when food scraps are left on their teeth. Dental bacteria will adhere to the surface of teeth and ferment, destroying children's teeth and producing tooth decay. In this case, you should take your child to the dentist as soon as possible, fill the decayed tooth, and then apply fluoride to prevent the child from decaying tooth. Children's deciduous teeth are also more important. Parents must pay attention to it. It cannot be said that deciduous teeth will be replaced sooner or later. Only when the baby's deciduous teeth are in good condition can the permanent teeth grow better!
