When Do Kids Teeth Finally Stop Growing In?

Posted on 6/15/2026 by NC Pediatric Dentistry

Ever wonder when your child's mouth will be finished getting all its teeth? It seems like they're always losing one or another when they're younger. Let's explore when those first teeth pop up and when the last ones finally make their appearance.

# The First Teeth: Baby Teeth

The very first set of teeth are called baby teeth, also known as primary teeth. These usually start showing up around six months old, and most kids have a full set of 20 baby teeth by the time they are three years old. These teeth are super important! They help kids chew food properly, speak clearly, and save space in the jaws for the adult teeth that will come later.

# Losing Baby Teeth: Making Way for Adult Teeth

Around the age of six, the fun really starts – the losing of baby teeth begins! As the adult teeth develop beneath the gums, they start to dissolve the roots of the baby teeth. This makes the baby teeth loose and eventually fall out. This process usually continues until around age 12. It’s a gradual process, so don't be surprised if you find a tooth under the pillow for many years!

# The Arrival of Adult Teeth

As baby teeth are lost, adult teeth erupt, taking their place. Most children will have all 28 of their adult teeth (excluding wisdom teeth) by the time they reach their early teens. These adult teeth are larger and stronger than baby teeth, designed to last a lifetime with proper care. Remember, taking good care of these permanent teeth with brushing, flossing, and regular dental visits is essential for a healthy smile.

# The Wisdom Teeth Question

Now, let's talk about wisdom teeth, also known as third molars. These are the last teeth to erupt, and they usually make their appearance between the ages of 17 and 25. However, not everyone gets wisdom teeth, and for some, they may never erupt fully.

Sometimes, there isn't enough room in the mouth for wisdom teeth to come in properly. This can lead to impacted wisdom teeth, which can cause pain, infection, and other dental problems. In these cases, a dentist might recommend removing the wisdom teeth. The decision to remove wisdom teeth is based on individual needs and a careful evaluation by a dental professional.

# Taking Care of Teeth at Every Stage

Whether it’s baby teeth or adult teeth, taking good care of your child’s smile is essential. Proper oral hygiene habits, like brushing twice a day with fluoride toothpaste and flossing daily, are important. Regular dental check-ups are also crucial to ensure that teeth are developing properly and to catch any potential problems early on. A healthy diet that limits sugary snacks and drinks also plays a big role in keeping teeth strong and healthy.
