Shark Teeth in Kids: A Cause for Concern?

If you’ve noticed two rows of teeth in your child’s mouth—like a mini shark—you’re probably wondering if this is something to worry about. Shark teeth, or ectopic eruption, are quite common in children and often resolve on their own. But when they don’t, they can create issues that require treatment.

In this blog, we’ll walk through what shark teeth are, what causes them, potential problems they can cause, and the treatment options available.

Key Takeaway

Shark teeth are common and often fix themselves, but if your child’s baby tooth doesn’t fall out or causes crowding, it’s best to see your family dentist.

What Are Shark Teeth?

Shark teeth refer to a condition where your child’s permanent tooth grows in behind the baby tooth, creating a double row of teeth, much like a shark’s. 

Normally, baby teeth fall out to make room for adult teeth, but with shark teeth, the primary tooth doesn’t budge, and the permanent tooth comes in behind it. This often happens with the lower front teeth but can also occur with the upper back molars.

Here are some common reasons why this happens:

  1. Delayed baby tooth loss: Sometimes, a baby tooth is slow to loosen or fall out, giving the adult tooth no choice but to erupt behind it.
  2. Stubborn baby teeth roots: The roots of the baby teeth may not dissolve properly, making it harder for them to fall out on time.
  3. Oral development issues: Occasionally, the child’s overall oral development is out of sync, causing the permanent teeth to come in too soon or too late.

What Do Shark Teeth Look Like?

If your child has shark teeth, you’ll likely notice:

  • Two distinct rows of teeth—one behind the other.
  • The baby tooth may still be in place, but it’s often loose.
  • Crowding or overlapping, especially as the new adult tooth tries to push through.

Potential Problems Caused by Shark Teeth

While these teeth often fix themselves, they can lead to complications in some cases:

  • Crowded teeth: The extra set of teeth can cause the mouth to become crowded, pushing teeth out of alignment.
  • Misaligned teeth: If the permanent teeth don’t erupt in their proper position, it can affect your child’s bite and oral health.
  • Orthodontic issues: This condition may lead to the need for orthodontic care down the line if the new teeth grow-in crooked or crowded.
  • Tooth decay: Extra teeth can make it harder to clean all surfaces properly, which could lead to tooth decay and gum problems.

Treatment Options for Shark Teeth

Watch and Wait

In many cases, the best approach is to wait and let nature take its course. These teeth usually fall out on their own within a few weeks or months. If your child is comfortable and there’s no crowding or misalignment, waiting might be all you need to do. However, always get a check-up if you have any questions–i.e. if the bite doesn’t feel right, definitely get it checked out.

Tooth Extraction

If the baby tooth is particularly stubborn or if there’s significant crowding, your dentist may suggest a tooth extraction to help the permanent tooth come into its correct position.

Orthodontic Care

In cases where shark teeth have caused misaligned teeth or severe crowding, orthodontic treatment might be necessary to straighten the teeth and ensure they’re in their proper place. This can help prevent further oral health problems as your child grows.

When to See a Dentist

It’s always a good idea to keep up with regular dental check-ups to monitor your child’s oral health. However, if you notice extra teeth, it’s important to visit your dentist if:

  • the baby tooth hasn’t fallen out after two months
  • there is pain or discomfort
  • you see signs of crowding or misaligned teeth
  • your child has difficulty chewing or speaking due to the extra teeth

Your dentist will assess the situation through a visual exam and may recommend a treatment plan, whether that’s monitoring the situation or proceeding with a tooth extraction.

Preventing Shark Teeth

Shark teeth are out of your control, but you can promote healthy oral development.

  • Encourage good oral hygiene practices, including brushing with fluoride toothpaste.
  • Limit sugary foods that can cause tooth decay.
  • Bring your child for routine check-ups to track their dental development and catch any potential issues early.
