My Child Has Two Rows of Teeth. Is That Normal?
If you have noticed a second row of teeth coming in behind your child’s baby teeth, it can look surprising or even concerning. Many parents refer to this as “shark teeth,” and while it may not look typical, it is actually a common part of dental development for some kids.
Here is what is happening and when you may want to have it checked.
What Causes Two Rows of Teeth?
As children grow, their permanent teeth begin to develop and push on the roots of their baby teeth. This process usually causes the baby teeth to loosen and fall out, making space for the new teeth to come in.
In some cases, the permanent teeth begin to erupt before the baby teeth have fully loosened. When this happens, the new teeth may come in behind the baby teeth, creating the appearance of two rows.
Where It Happens Most Often
This situation most commonly occurs with the lower front teeth around ages 5 to 7. It can also happen with the upper front teeth, though less frequently.
Because these are often the first permanent teeth to come in, the timing between baby tooth loss and new tooth eruption does not always line up perfectly.
Is It Normal?
In many cases, yes, this is a normal part of development. Once the baby tooth becomes loose and falls out, the permanent tooth often moves forward into a more natural position over time.
Children’s jaws are still growing, and this growth helps create space for teeth to shift into place.
What Parents Can Do
If you notice two rows of teeth, you can encourage your child to gently wiggle the baby tooth if it is loose. This can help it fall out naturally and make room for the permanent tooth.
Continue with regular brushing and flossing to keep the area clean, especially since food can get trapped more easily during this stage.
When to Call the Dentist
While this situation is often harmless, there are times when a dental visit is a good idea. You should have it evaluated if:
The baby tooth is not becoming loose
The permanent tooth continues to come in further behind the baby tooth
Your child is experiencing pain or discomfort
You are unsure if things are progressing normally
In some cases, the dentist may recommend removing the baby tooth to allow the permanent tooth to move into the correct position.
Will the Teeth Straighten Out?
Many times, the permanent teeth will shift forward on their own once the baby tooth is gone. However, every child is different, and some may need monitoring as their teeth and jaw continue to develop.
Regular dental visits help ensure everything is moving in the right direction.
Conclusion
Seeing two rows of teeth can be surprising, but it is often a normal part of your child’s dental development. With time, growth, and proper care, teeth usually move into place on their own.
