“Shark Teeth” in Kids: Why Adult Teeth Grow Behind Baby Teeth and What to Do

Seeing a second row of teeth appear behind your child’s baby teeth can be surprising. Many parents immediately worry that something is wrong. Fortunately, this common dental condition is often referred to as “shark teeth” because it resembles the multiple rows of teeth seen in sharks. In most cases, it is a normal part of dental development and can be managed with the right care.

At Sturz & Abby Pediatric Dentistry and Orthodontics, we help families understand every stage of their child’s oral development. If you notice adult teeth growing behind baby teeth, knowing why it happens and when to seek professional advice can help protect your child’s healthy smile.

What Are “Shark Teeth” in Kids?

“Shark teeth” occur when a permanent tooth begins to erupt before the corresponding baby tooth has fallen out. Instead of replacing the baby tooth immediately, the adult tooth emerges behind it, creating the appearance of two rows of teeth.

This situation is especially common in children between the ages of 5 and 7, particularly with the lower front teeth. While it may look unusual, it is often a temporary phase during the transition from primary to permanent teeth.

Why Do Adult Teeth Grow Behind Baby Teeth?

Several factors can contribute to shark teeth:

Baby Tooth Roots Haven’t Fully Dissolved

Normally, the roots of baby teeth dissolve as permanent teeth push upward. If the roots dissolve slowly, the baby tooth remains in place while the adult tooth starts emerging behind it.

Permanent Teeth Follow a Different Path

Sometimes the permanent tooth develops at a slightly different angle, causing it to erupt behind rather than directly beneath the baby tooth.

Genetics

Family history can influence how children’s teeth develop. If parents experienced delayed baby tooth loss or crowded teeth, their children may have a similar pattern.

Crowded Teeth

Limited space in the jaw may encourage permanent teeth to erupt out of their usual position until more room becomes available.

Are Shark Teeth a Dental Emergency?

In most cases, shark teeth are not considered a dental emergency. Many baby teeth become loose and naturally fall out within a few weeks after the permanent tooth appears.

Parents can encourage the process by having children:

• Wiggle the loose baby tooth with clean fingers.
• Eat crunchy fruits and vegetables when appropriate.
• Maintain excellent brushing and flossing habits.

However, monitoring the situation is important to ensure proper tooth alignment.

When Should Parents Schedule a Dental Visit?

Professional evaluation is recommended if:

• The baby tooth remains firm after several weeks.
• The permanent tooth continues growing without movement of the baby tooth.
• Your child experiences pain, swelling, or discomfort.
• Several teeth appear crowded.
• You notice unusual tooth positioning.

A pediatric dentist can determine whether the baby tooth simply needs more time or requires gentle removal to allow proper eruption.

How Are Shark Teeth Treated?

Treatment depends on your child’s individual situation.

Observation

Many children only need regular monitoring because the baby tooth loosens naturally as the permanent tooth continues to erupt.

Baby Tooth Extraction

If the baby tooth refuses to loosen, the dentist may recommend removing it. This creates space for the permanent tooth to gradually move into its proper position.

Monitoring Tooth Alignment

After the baby tooth falls out or is removed, the permanent tooth often shifts forward naturally with normal tongue movement and jaw growth.

Orthodontic Evaluation

If crowding or bite issues are present, your dentist may recommend an orthodontic assessment to determine whether future treatment will be beneficial.

Can Shark Teeth Correct Themselves?

Yes. In many children, the permanent tooth gradually moves into the correct position after the baby tooth falls out. Every child develops differently, so regular dental checkups help ensure everything progresses normally.

The earlier any alignment concerns are identified, the easier they may be to manage during growth.

How Parents Can Help at Home

While waiting for the baby tooth to loosen, parents should:

• Encourage brushing twice daily.
• Help children floss around crowded teeth.
• Watch for changes in tooth movement.
• Avoid trying to pull out firmly attached baby teeth.
• Continue regular dental visits for monitoring.

Good oral hygiene prevents plaque buildup around overlapping teeth and supports healthy gums during this transitional stage.

Helping Your Child Maintain a Healthy Smile

Although shark teeth may look alarming, they are usually a normal part of childhood dental development. Most cases resolve naturally, while others simply require a minor dental procedure to guide proper eruption. Prompt evaluation can prevent unnecessary complications and provide peace of mind for parents.

Frequently Asked Questions

1. What causes shark teeth in children?

Shark teeth develop when a permanent tooth erupts before the baby tooth falls out. Slow root resorption, tooth positioning, crowding, or normal developmental differences may contribute.

2. Are shark teeth normal?

Yes. Shark teeth are fairly common during the transition from baby teeth to permanent teeth, especially in children around six years old, and many cases resolve without major treatment.

3. Should I pull out my child’s baby tooth?

Avoid removing a baby tooth if it is firmly attached. Pulling it too early may cause discomfort or injury. Allow natural loosening or seek professional guidance if it remains stable.

4. How long should I wait before seeing a dentist?

If the baby tooth does not become loose after a few weeks, or if discomfort, swelling, or crowding develops, a dental examination can determine the best next step.

5. Will the permanent tooth move into place on its own?

Often it does. Once the baby tooth falls out or is removed, the permanent tooth may gradually shift into a better position as the jaw continues to grow.

6. Can shark teeth lead to crooked teeth?

They can contribute to alignment concerns in some children, especially when there is limited jaw space. Each case varies depending on growth and tooth positioning.

7. At what age do shark teeth usually appear?

Shark teeth most commonly appear between ages 5 and 7 when the lower front permanent teeth begin replacing baby teeth, although they may occur with other teeth as well.
