Why new born baby not have teeth?

Newborn babies don't have teeth because:

* Development: Teeth develop in the womb, but they don't erupt until later. The process of tooth development starts around the sixth week of pregnancy, but the enamel and dentin (the hard parts of the tooth) only fully form after birth.

* Nutrition: A newborn's primary source of nutrition is breast milk or formula, which is soft and doesn't require chewing. Teeth would be more of a hindrance than a help during this stage.

* Jaw Development: The jaw bones and muscles need time to develop and grow strong enough to support teeth.

* Safety: Having teeth could be dangerous for a newborn, as they might accidentally bite themselves or others.

When do teeth start to erupt?

Typically, the first baby teeth (primary teeth) start erupting around 6 months of age, although some babies might start a bit earlier or later. The process of getting teeth can be uncomfortable for babies, causing them to drool, fuss, and chew on things.
