How Long Does it Take for Permanent Teeth to Come In? | Junior Smiles of Stafford

It’s common for parents to be excited about their baby’s first set of permanent teeth, especially if there’s one missing tooth–making a gap in teeth. These kids might look cute with a gappy grin, but as a parent, you still can’t help but worry about it. 

Around the age of six, most children lose their first primary tooth, and the Tooth Fairy continues to visit them until they are between the ages of 12 and 13 years old. It takes about six months for an adult tooth to erupt in its place once the baby tooth has fallen out. However, if your child is taking longer than expected, you may begin to wonder whether something is wrong.

The question remains, “how long does it take for permanent teeth to come in?” This blog will ease your worries away! Keep reading to learn more about your child’s teeth!

What could be the reasons?

Why does an adult tooth appear late, sometimes? The delay could also be because of the speed of tooth growth, but that is not always the case. A dentist will be able to figure out why it’s taking so long for the teeth to come in.

Wrong Direction or Directional Problems

There have been times in the past when teeth have had their own minds and have tried to break through the gums instead of going along with the primary tooth’s route. Even if they had all the space in the world, this can still happen. As a result, parents may notice that their child’s permanent teeth aren’t coming in as straight as they should be.

As a result, the permanent tooth may become wedged between two baby teeth that haven’t yet fallen out of the gum line. In this case, either orthodontics or tooth extraction is recommended as a solution. To figure out the issue, the dentist may use x-rays.

Congenitally Missing A Tooth

This is a genetic condition, one of the family members has the same condition. This is a common issue; however, some people may not be able to realize it sooner. When a person has congenitally missing teeth, their permanent teeth never come in. As long as there’s nothing to push them out, the baby’s primary teeth are likely to remain in place.

If they are lost because of tooth decay, gum disease, or trauma, no permanent tooth exists to take its place. A bridge or partial denture can be used to replace the missing tooth. You could talk to your child’s pediatric dentist to know which orthodontic treatment would suit them best.

Eruption Failure

Primary Failure of Eruption (PFE) is genetic, and it rarely happens. This occurs when the permanent teeth are present but do not erupt, or only partially erupt, and then stop. When numerous teeth are involved, treatment can take several years and involve several distinct steps. The most typical method is to coax the teeth out through oral surgery and orthodontic treatment.

On the other hand, there is also a condition called a mechanical failure of eruption, which may involve ankylosis. This occurs when the tooth or teeth are fused to the bone and cannot be extracted.

Supernumerary Primary Teeth

These are extra teeth. They can happen in conjunction with other diseases such as cleft palate, Gardner’s syndrome, or cleidocranial dysostosis, or they can occur on their own. These extra teeth may appear anywhere in the dental arch and have the potential to obstruct the permanent teeth.


The development of your child’s teeth is strongly influenced by their diet. Calcium is the primary nutrient teeth need to be strong enough to break through the gum line. Because of this, calcium- and nutrient-rich foods are essential for your child’s well-being. Avoiding sugary food and drinks is another way to promote healthy tooth development.
