When Do Permanent Teeth Start To Come In Growing Children?

We are very much familiar with the whole tooth eruption process, babies grow their first set of teeth. It is not the time a parent can easily forget; nagging, crying episodes, fever, and overall disruption. However, that is not the case when permanent teeth come in.

The question is, when do the permanent teeth start making their way into the mouth? Well, each tooth that erupts has its own timeline of growth and pattern. Let’s discuss it further for better comprehension of the topic.

When Do Permanent Teeth Come In?

The permanent teeth start coming in at the age of five or six. The pattern this set follows is the same as baby teeth. Firstly, the bottom ones pop out, then the upper two, followed by canines, and finally the molars.

Naturally, the first baby tooth to erupt is the first one to loosen up and fall off. However, in case of any injury, trauma, or another medical factor, any tooth may knock up and fall off. Usually, the maximum amount of permanent teeth come in when a child reaches twelve or thirteen max.

This set of teeth include incisors, canines, and molars. Two of the molars amongst the permanent teeth come in without replacing baby teeth. These teeth are called first molars; they are the reason to increase the number of teeth from twenty to twenty four.

It is after the arrival of these first molars the baby teeth start falling off, making way for others to come in the pattern mentioned above.

What Are the Reasons of a Child’s Permanent Set Not Erupting?

There are certain circumstances when the permanent teeth fail to come in at the right time. There are a few scenarios linked to it, which are.

  • Most commonly, the reason why next set of teeth do not erupt on time is due to inadequate space. In such cases, the dentist may recommend getting the neighboring tooth extraction to provide better space for growth.
  • The permanent tooth may have an inclined position which makes its eruption a problem. so, the dentists perform surgery according to the root cause of the issue.
  • Hypodontia is a condition where the tooth does not fully grow and matures to pop out. This issue may or may not need surgical intervention. Usual treatment includes dental implants or bridges.
  • Another phenomenon that is not fully known is the primary failure of eruption. There is enough space in such cases, and the tooth has developed properly, yet the eruption fails to occur.
