🌟 Baby teeth

A child has 20 temporary baby teeth that start coming in during the first year. Then they fall out one by one from about age six, and bigger permanent teeth grow in their place.

💡 What's inside a tooth?

A tooth is covered on the outside by enamel, the hardest material in the body; under it is a layer called dentine, and in the middle is the pulp, with nerves and blood vessels.
