Have you noticed your child’s new adult teeth coming in behind their baby teeth? You may see what looks like two rows of teeth, especially along the bottom front of your child’s mouth. While this can look concerning, it is actually a fairly common part of childhood dental development!
At Inspire Kids Dental in Ooltewah, TN, we help parents understand what is normal as their children lose their baby teeth and welcome their permanent smiles. Here is what you need to know if your child’s permanent teeth are coming in before their baby teeth fall out.
Why Are Permanent Teeth Growing Behind Baby Teeth?
When permanent teeth begin to erupt before baby teeth have fallen out, children can temporarily develop what parents often call “shark teeth.” This nickname comes from the appearance of two rows of teeth, similar to a shark’s mouth.
This most commonly happens with the lower front teeth, although it can occur in other areas of the mouth.
Normally, as a permanent tooth develops beneath a baby tooth, it helps trigger the gradual breakdown of the baby tooth’s root. As the root dissolves, the baby tooth becomes loose and eventually falls out, allowing the permanent tooth to take its place.
Sometimes, however, the permanent tooth erupts behind the baby tooth instead of directly beneath it. The baby tooth may not have loosened enough to fall out yet, leaving both teeth visible at the same time.
The good news is that this often resolves naturally as the baby tooth becomes loose and falls out.
Is It Normal for Adult Teeth to Come in Behind Baby Teeth?
Yes! It is relatively common, particularly when the lower permanent front teeth begin to erupt.
Children typically start losing their baby teeth around age 6, although the timing varies from child to child. The lower permanent front teeth are often among the first adult teeth to appear.
If your child has a permanent tooth coming in behind a baby tooth, it does not automatically mean something is wrong. In many cases, the baby tooth will loosen and fall out on its own, and the tongue will gradually help move the permanent tooth forward into a more natural position.
However, every child’s mouth develops differently. If the baby tooth remains firmly in place or the permanent tooth appears significantly out of position, a pediatric dentist can evaluate whether any intervention is needed.
What Should I Do If My Child Has Shark Teeth?
If you notice two rows of teeth, there is usually no need to panic. Here are a few steps you can take at home.
1. Check Whether the Baby Tooth Is Loose
Gently check whether the baby tooth moves when your child wiggles it with their tongue or a clean finger. If it is loose, it may be close to falling out naturally.
Encourage your child to gently wiggle the tooth if it is comfortable, but do not force it.
2. Avoid Pulling the Tooth Too Early
It can be tempting to pull the baby tooth when you see a permanent tooth growing behind it. However, avoid forcing a tooth out before it is ready. Pulling too aggressively can cause unnecessary pain, bleeding, or injury to the surrounding gum tissue.
If the baby tooth is not loosening or you are unsure whether it needs to be removed, let your pediatric dentist evaluate it.
3. Keep Brushing and Flossing
When two teeth sit close together, food and plaque can collect in the space between them. Help your child brush carefully around both teeth and continue flossing wherever the teeth touch.
Keeping the area clean helps protect the gums and reduces the risk of cavities while the teeth are transitioning.
4. Schedule a Dental Evaluation if Needed
If the baby tooth remains firmly in place, your child experiences discomfort, or the permanent tooth appears crowded or significantly out of position, contact your pediatric dentist.
A dental examination can help determine whether the tooth simply needs more time or whether treatment should be considered.
When Should I Worry About Permanent Teeth Growing Behind Baby Teeth?
Although this situation often resolves on its own, there are times when a dental visit is especially important.
Consider scheduling an appointment if:
-
The baby tooth is not becoming loose even though the permanent tooth has erupted substantially.
-
The permanent tooth appears severely crowded or out of position.
-
Your child has persistent pain, swollen gums, or bleeding that does not resolve.
-
The baby tooth is interfering with eating or brushing.
-
You notice other concerns about how your child’s teeth fit together.
A pediatric dentist can assess the position of the teeth, the condition of the baby tooth, and your child’s overall dental development. Depending on the situation, the dentist may recommend monitoring the teeth, removing a retained baby tooth, or evaluating whether additional orthodontic assessment is appropriate.
Seek prompt dental care for significant swelling, severe pain, or signs of infection.
Will My Child’s Permanent Teeth Move Into the Correct Position?
In many cases, yes. Once the baby tooth falls out, the permanent tooth may gradually move forward into a more typical position. The tongue and the natural growth of the mouth can help guide this process.
However, not every tooth will move into the ideal position on its own. Crowding, limited space in the dental arch, and other developmental factors can affect how permanent teeth align.
Your pediatric dentist can monitor your child’s progress and determine whether the teeth are settling into place as expected.
How Can I Help My Child Maintain a Healthy Smile During This Stage?
Losing baby teeth is a normal milestone, but it is still important to maintain good oral hygiene throughout the transition.
Help your child:
-
Brush twice daily with fluoride toothpaste.
-
Floss daily between teeth that touch.
-
Drink water regularly and limit frequent sugary snacks and drinks.
-
Avoid forcing loose teeth out before they are ready.
-
Attend regular dental checkups so changes in tooth development can be monitored.
These simple habits help protect both baby teeth and newly erupting permanent teeth.
