Our teeth present in our mouth are not only responsible for chewing our food, but they also help us to maintain the shape and structure of our jaw. So, the answer to the question “why do we have two sets of teeth” is because the permanent set of 32 adult teeth are too big for a baby’s jaw. The baby teeth are there to ensure the proper structure of our jaw, speech development, and easy chewing of food during childhood. Once the jaw is fully set and the skull is not growing anymore, the primary teeth start to fall out.

Another reason for having two sets of teeth is that the teeth can’t grow. Once they are fully grown, they will stay in the same size and that is why a human needs two sets of teeth to adjust the change in our jaw sizes over time.

Infraocclusion: Baby teeth will remain in a permanent position while the teeth right next to them will continue to erupt
