A second row of teeth appearing behind your child’s smile can stop any parent mid-sentence, especially when the baby tooth in front refuses to budge. These double rows earn the nickname shark teeth, and they are a common stage of growing up that often resolves on its own with time. If the baby tooth stays firmly in place, though, a dental visit may be a good idea.
At Guadalupe Kids Dental in Seguin, we see this surprise often, and we are here to help you sort out what is normal and what needs attention. Our board-certified pediatric dentist, along with our team, provides compassionate, family-centered care, including pediatric dental extractions when a stubborn baby tooth needs help making room for the permanent tooth.
What Are Shark Teeth in Kids?
Shark teeth happen when a permanent tooth comes in behind a baby tooth that has not fallen out yet. For a while, your child may have a double row, much like the layered teeth in a shark’s mouth. Parents often notice it along the lower front teeth, because the adult teeth on the bottom usually arrive first, around the time baby teeth start loosening at about age six.
In most cases, a double row does not cause pain or infection, so it often looks more worrisome than it is. The good news is that the new tooth may move into a better position once the baby tooth is out of the way, thanks to the natural push of the tongue.
What Causes Shark Teeth in Children?
Baby teeth are built to make way for adult teeth. As a permanent tooth grows, it usually presses against the root of the baby tooth above it, and that pressure gradually dissolves the root until the baby tooth loosens and falls out. Shark teeth may appear when the permanent tooth takes a slightly different path and erupts behind the baby tooth instead of beneath it.
When that happens, nothing presses against the root of the baby tooth, so it may stay firmly in place while the permanent tooth keeps coming in behind it. Shark teeth can appear on the top or bottom, and they may show up again as more adult teeth arrive during childhood.

What to Do at Home When You Spot Shark Teeth
Most families can start with simple steps at home while the baby tooth works its way loose. Guidance from Nationwide Children’s Hospital notes that baby teeth in a double row most likely fall out by themselves with time, so patience and steady habits go a long way. Here are a few ways you can support your child in the meantime:
- Keep brushing: brush twice a day and floss around the baby teeth to keep gums healthy and help prevent cavities.
- Encourage wiggling: if the baby tooth is very loose, invite your child to wiggle it out on their own.
- Avoid forcing it: if the baby tooth is still firmly attached, skip the tugging and let us take a look first.
- Stay on schedule: keep up with dental checkups every six months so we can watch how the new tooth is coming in.
Staying calm and keeping up your child’s routine are often the best first steps. Our focus on preventive care means we are always happy to walk you through what you are seeing and what to watch for next.
When to See a Pediatric Dentist for Shark Teeth
Shark teeth are usually not an emergency, but some situations deserve a closer look. Once the permanent tooth is as tall as the baby tooth and the baby tooth still has not loosened, a dentist may recommend removing the baby tooth to give the adult tooth a clear path. You should also reach out if your child has pain, swelling, or trouble chewing.
During a visit, we may take pediatric X-rays to see where the permanent tooth is positioned. From there, we can explain whether watching and waiting makes sense or whether a simple extraction may help your child feel comfortable. Our goal is always the most conservative care that fits your child’s needs.
