Baby Teeth to Adult Teeth

Dentist in Easton Describes how Your Smile Grows over the Years

Have you ever wondered about the difference between baby teeth and adult teeth? Each has a different purpose and use but both are equally important. Here’s what you should know about the transition from baby teeth to adult teeth with the help of your dentist in Easton.

Primary Teeth

Primary teeth, also known as baby teeth, are not permanent and will not remain in the mouth. During childhood, the jaw will grow and create more space for permanent teeth to come in.

Between the ages of six and 12, children will begin losing their primary teeth. As these leave, the room is made for the permanent teeth to emerge. There is a period that is referred to as “Mixed Dentition,” which means that children have both primary teeth and adult teeth. The permanent teeth will form under the gum line before they erupt.

As the crown of the tooth is formed, it will begin to bud and push the primary tooth out. During this time, it doesn’t yet have a root, but the roots will form later.

Permanent Teeth

Over time, these 20 primary teeth will fall out completely and make room for a total of 32 permanent teeth. The primary molars are replaced by permanent premolars or otherwise known as bicuspids. The permanent molars will emerge behind the primary teeth.

Normally, the first teeth to emerge will be the lower front teeth. These are called incisors. Next, will come the upper and lower first molars. This is the set closest to the front of the mouth. Then, the upper two front teeth will emerge. Keep in mind that this order can vary depending on the child.

Above all, parents should pay attention to symmetry. That means the same teeth should come in on each side around the same time. This is a sign that everything is running the way it should.


Dental health is important during this transition in your child’s mouth. Ensure that they are brushing twice a day and flossing once. Parents should also be making sure to take them to their bi-annual dental visit for professional cleanings and exams.
