Hey there! Have you ever wondered why we have baby teeth first before getting our adult teeth? Let’s dive into the world of teeth and find out!
Most mammals, including us humans, have two sets of teeth in our lifetime. This is called being “diphyodont.” We start with a set of 20 baby teeth, also known as deciduous teeth. These teeth are already developed inside our jaws when we’re born. Sometimes, babies are even born with teeth showing, which are called natal teeth. But usually, baby teeth start to come out when we’re about 6 months to 2 years old.
Baby teeth are super important! They help us chew our food, learn to speak, and strengthen the muscles in our mouths. They also make space in our gums for our adult teeth to grow in later. As we grow, our mouths get bigger, and eventually, the 20 baby teeth become too small. If we kept them, they wouldn’t fit well in our adult mouths, making it hard to chew.
When we reach around age 6, our baby teeth start to fall out, and our permanent teeth begin to come in. Unlike us, some animals, like alligators, can replace their teeth many times throughout their lives. But humans only get one set of adult teeth, so it’s really important to take good care of them!
Taking care of your teeth means brushing them every day and visiting the dentist regularly. If you don’t, you might run into problems like cavities or gum disease. So, make sure to keep those teeth clean and healthy!
Do you have any fun stories about losing your teeth? Maybe you still have some baby teeth left? We’d love to hear about it! Remember to keep learning and exploring more about the amazing world of science and health!
Tooth Timeline: Create a timeline of your own teeth journey! Ask your parents when you got your first baby tooth and when you lost your first one. Draw pictures of your teeth at different stages and label them. Share your timeline with your classmates and see how everyone’s tooth journey is unique!
Tooth Detective: Become a tooth detective! Observe the teeth of different animals (you can look at pictures or videos). How are they different from human teeth? Why do you think some animals have sharp teeth while others have flat ones? Discuss with your friends or family what you discover about how teeth help animals eat their food.
Healthy Teeth Challenge: Start a “Healthy Teeth Challenge” with your family. Make a chart to track your brushing habits for a week. Try to brush twice a day and floss once a day. At the end of the week, see who in your family did the best job of taking care of their teeth. Talk about why keeping your teeth clean is important and how it helps your adult teeth stay healthy.

Hello everyone, Trace here with another DNews short! Teeth are incredibly important for us. They help us chew our food and break it down for digestion. So, why aren’t we born with the adult teeth we have later in life? What is the purpose of having baby teeth first?
Most mammals, including humans, are diphyodonts, which means we grow two sets of teeth in our lifetime. This is because baby mouths can’t accommodate a full set of 32 adult teeth. Instead, we start with a set of 20 baby teeth, also known as deciduous teeth. Interestingly, we are born with these teeth already developed inside our jaws! In rare cases, some babies can even be born with teeth already visible, known as natal teeth. For most, these baby teeth begin to emerge at around 6 months to 2 years old.
Children need these deciduous teeth to chew food, develop their speech, and strengthen the muscles in their mouths. Perhaps most importantly, baby teeth create space in our gums for adult teeth to grow in later. They act as placeholders while larger teeth develop underneath. As we grow, our mouths expand and eventually become too large for the 20 baby teeth. If we retained our initial set of teeth, they would be too small for our adult mouths, leading to significant gaps and making chewing very difficult.
When baby teeth start to fall out around age 6, a set of permanent teeth emerges! Many animals do not follow this two-set system. For example, an alligator can replace its teeth roughly 50 times in its lifetime. Unfortunately, humans do not have that same ability. After childhood, we only get one set of teeth, which is why it’s crucial to take care of them.
But what happens if you neglect dental hygiene? You can find out more about that in this video. What about you? Do you have any interesting stories about losing your teeth? Do you still have some baby teeth? Let us know! Don’t forget to subscribe and keep coming back for more DNews every day.
