Tooth eruption is the process of teeth breaking through the skin and emerging into view. Most individuals experience the process of having two sets of teeth come in their mouth at different times during the course of their lifetime. The first set, “primary” teeth – or baby teeth. And then our “permanent” teeth. These typically start to emerge at age 6 and stay with us throughout our adult lives.

Note that heredity and several other factors have an impact on the age in which children grow their permanent teeth. There are some guidelines, but each child is different.

The very first of the permanent teeth start to come out in the mouth between the ages of 6 and 7. These are the molars. Professionals call these teeth the “six-year molars”. These are new teeth and do not replace any of the baby teeth located within the mouth.

These require special care to ensure that they not only serve their purpose but that they last throughout adulthood. They aid in shaping the bottom of the facial region and also impact the position and general health of the other teeth that will erupt in the mouth.

By the age of 13, nearly all other permanent teeth will erupt in the mouth. This makes a total of 28 teeth that will come in between the age of 6 and the age of 13. These teeth include 4 lateral incisors, 4 central incisors, 4 canines, 8 premolars, and 8 molars.

The very last of the permanent teeth that will erupt in the mouth are called “3rd molars”. These are the wisdom teeth.

The eruption of wisdom teeth commonly occurs between the age of 17 and the age of 21.

In some instances, these may come in only halfway or may be impacted. Since they are not critical to chewing and are very difficult to care for, many dentists will recommend the removal of the wisdom teeth.

In most instances, girls will start to lose their baby teeth and growing permanent teeth earlier than boys.

When the baby teeth start to fall out, the first to go is typically the one located on the front region of the lower section of the jaw. Just like when the primary teeth erupt, children will experience some degree of discomfort when the teeth start to fall out and when the permanent teeth start to erupt within the mouth.

If you find that this happens with your child, you may use a variety of cold compresses, pain medications, and those that combat inflammation in order to help them cope. You may also contact a pediatric dentist for ideas on how to help your child cope with pain.

The permanent teeth develop inside of the jaws when a child is born. This process continues until the primary teeth are lost and the adult teeth start to push through.

By the time that your child reaches the age of 21, they will usually have right around 32 of the permanent teeth. This is a total of 16 in both the upper and the lower regions of the jaw.

In some cases, the wisdom teeth will never erupt in the mouth or only a couple will erupt. Due to this fact, it is normal to have a total of 28 to 32 teeth by the age of 21. You may use the following tooth eruption chart as a guideline to determine when your child’s permanent teeth may be erupting.

When your child’s very first tooth erupts as a baby, it is imperative that you set up an appointment with a pediatric dentist.

This professional will help you learn how to care for your baby’s teeth and will monitor the eruption of their teeth to ensure that they are meeting the standard guidelines for tooth eruption.

Furthermore, they can prescribe fluoride and even put sealants on all of the teeth to ensure that they remain as healthy as possible as your child grows. If you would like to learn more about tooth eruption or would like to set up an appointment with a pediatric dentist, contact us today!
