Double Row Teeth | Shark Teeth Alert! for Lafayette Parents

November 24, 2025

Finding a second row of teeth erupting behind your child’s baby teeth can be startling for any parent in the Lafayette, LA area, but rest assured, this phenomenon is often called "shark teeth," and it is usually easy to handle. This dental phase is quite common, affecting up to 30% of kids during their transition period. Your local pediatric dental team is ready to help guide your family through this awkward stage, ensuring your child develops a healthy smile. This situation typically occurs between the ages of six and seven, most frequently involving the lower front teeth.

Why Does Ectopic Eruption Cause the Double Row?

Normally, the process of losing a tooth is straightforward. The permanent tooth develops beneath the gum line, dissolving (resorbing) the root of the baby tooth, causing it to loosen and fall out.

The Shark Teeth Mechanism: Ectopic Eruption

"Shark teeth" occur when the roots of the baby tooth do not dissolve and remain solid, acting as an anchor. Since the root does not loosen, the permanent tooth must find an alternate path, erupting through the gums behind the baby tooth. This deviation is called Ectopic Eruption. Contributing factors for this variation include genetics, alternative eruption paths, and sometimes space constraints, where there is simply not enough room for the larger adult teeth.

Is My Child’s Double Row a Sign of Hyperdontia?

The sources acknowledge that "double row teeth" can be linked to the concept of Hyperdontia. Hyperdontia is the medical term for having extra teeth, meaning more than 20 primary or 32 permanent teeth.

However, the vast majority of common double rows observed in children aged six to seven are actually a timing issue or positional error. It is an ectopic eruption of a normal adult tooth, not the formation of a supernumerary tooth bud, which defines true Hyperdontia.

What Should Lafayette Parents Do First?

The good news is that parents often play the most important role in the initial management of "shark teeth."

Step 1: Monitor and Encourage the Wiggle Test

If the baby tooth is even a little loose, encourage your child to gently wiggle it several times a day. If the baby tooth is lost, the tongue’s natural pressure will often guide the new permanent tooth forward into the correct position. Simple actions like encouraging crunchy foods may also help loosen the tooth. It is a Crucial Warning to never try to forcibly pull a tooth that is not ready, as this can cause damage or pain.

Step 2: The Two-Month Rule for Your Local Dentist

If the adult tooth has already erupted, but the baby tooth is not loose and feels solid, or if the two rows are now at the same height, an appointment with your Lafayette pediatric dentist is necessary. If you are unsure, a practical timeline is to wait about two months after the adult tooth appears, or if the baby tooth remains firmly attached after 4–6 weeks. If it remains solid at that point, evaluation is required.

When Should We Visit a Local Pediatric Dentist?

When the baby tooth refuses to vacate its spot, professional help is key to preventing long-term damage.

The Pediatric Dentist’s Role in Treatment

During the appointment, a dentist will perform an examination and likely take an X-ray to determine if the baby tooth’s root will loosen naturally or if assistance is needed. If extraction is necessary, the procedure is described as a relatively easy appointment. The removal is simpler than removing an adult tooth because baby tooth roots are smaller and often partially resorbed. Local anesthesia is used to ensure the child’s comfort. Once the baby tooth is removed, the constant pressure from the tongue naturally pushes the permanent tooth into position.

The Risk of Delay: Gingival Recession

If the baby tooth is not lost in a timely manner, there is a risk that the gums will attach too low to the permanent tooth. This delay can cause a gingival recession. This condition may require a gum graft when the child is older, making timely intervention crucial.

Will My Child Need Braces in the Future?

While extraction solves the immediate issue of the double row, this ectopic eruption can be an indication of future crowding in the mouth.

The existence of "shark teeth" suggests the child's mouth may not have sufficient room to accommodate the full set of permanent teeth. While removing the baby tooth allows the permanent tooth to move forward, regular dental monitoring ensures optimal outcomes. In some cases, there is a higher chance of needing braces or orthodontic treatment later on to manage the long-term crowding.

Frequently Asked Questions (FAQ) for Lafayette Families

1. Is this rare?

No, this is quite common, affecting approximately 30% of kids during dental transition.

2. Is it only the bottom front teeth?

While it is most frequent with the lower front teeth, it can also happen with the upper front teeth or back molars.

3. Will the adult tooth move forward?

Yes, once the baby tooth is removed (either naturally or by extraction), the tongue’s pressure typically guides the permanent tooth forward into the proper space.

4. Is the extraction painful?

No. The procedure is relatively easy because the roots are often partially dissolved, and local anesthesia is used to ensure the child is comfortable.

5. Can I prevent "Shark Teeth"?

No, this variation cannot be prevented, often due to genetics or jaw size. Early detection through regular dental visits helps reduce long-term complications.

6. What if my child feels pain?

Mild discomfort is expected when teeth are loose, but if your child experiences significant pain or difficulty eating, scheduling an appointment immediately is advised.

Analogy to Clarify Ectopic Eruption:

Think of your child's baby tooth as a parking spot anchor. When the new adult car (the permanent tooth) is ready to park, it normally dissolves the anchor and slides into the spot. With "Shark Teeth," the anchor does not dissolve, so the new adult car has to park right behind the baby car. Once the baby car (the baby tooth) is removed by the dentist, the tongue acts like a gentle push, guiding the adult car into its intended spot.
