You brush your child’s teeth before bed and notice something unusual. A new tooth is coming in, but it’s not where you expected. Instead of replacing a baby tooth, the permanent tooth is growing right behind it. Your child now has two rows of teeth in one spot.
This is called “shark teeth,” and it can be startling for parents. The good news is that this is a common occurrence in children’s dental development. While it may look concerning, it’s usually a normal part of childhood development that resolves on its own. Understanding what’s happening in your child’s mouth and when to seek professional guidance can help you feel confident about the next step.
What Are Shark Teeth?
Shark teeth refer to a double row of teeth that appears when permanent teeth erupt behind baby teeth that haven’t fallen out yet. The name comes from the way sharks have multiple rows of teeth in their mouths. In children, this happens when an adult tooth comes in before the baby tooth has loosened and fallen out naturally.
This common phase typically occurs during tooth eruption in the lower front teeth, though it can also happen with upper front teeth. The lower incisors are usually the first permanent teeth to come in, around age six or seven. This is often when parents first notice the double row.
Why Does This Happen?
Baby teeth are designed to fall out when the roots of baby teeth dissolve naturally. As a permanent tooth develops beneath the gumline, it pushes upward and breaks down the baby tooth’s root. This process loosens the baby tooth until it eventually falls out. The new tooth then moves into the correct position where the baby tooth once was.
Sometimes, though, the permanent tooth doesn’t line up perfectly with the baby tooth above it. The adult tooth may erupt at an unusual angle or in a spot where there isn’t enough room. When this happens, the permanent tooth comes in behind or in front of the baby tooth instead of directly underneath it. Because the permanent tooth isn’t pushing against the roots of the baby teeth, those roots don’t dissolve. The baby tooth stays firmly in place while the permanent tooth erupts anyway.
This stage of dental development is more common than many parents realize. It doesn’t mean something is wrong with your child’s oral health. It simply means the tooth eruption patterns didn’t follow the typical path.
Is It a Serious Problem?
In most cases, shark teeth are not a serious problem. Many children experience this as part of their dental journey, and the situation often corrects itself without professional intervention. The baby tooth may loosen and fall out on its own within a few weeks, allowing the permanent tooth to shift into a better position naturally.
Your child’s tongue and lips apply gentle pressure to teeth throughout the day. This pressure helps guide child’s permanent teeth into the right spots as they grow. Even if a permanent tooth starts out behind a baby tooth, it often moves forward once the baby tooth is gone.
However, there are times when the baby tooth doesn’t loosen on its own. If the baby tooth remains firmly in place for several weeks after the permanent tooth has fully erupted, the permanent tooth may not have enough space to move into the correct position. This is when a dental visit becomes important.
When Should You See a Pediatric Dentist?
You should schedule a dental visit if the baby tooth hasn’t become loose after a few weeks of the permanent tooth being visible. A pediatric dentist can evaluate your child’s mouth and determine whether the baby tooth needs to be removed. Waiting too long can lead to dental problems such as crowding or misalignment.
You should also contact your dentist if your child is experiencing discomfort or pain. While shark teeth are usually painless, some children may feel pressure or irritation in the area. A dentist can assess the situation and provide compassionate care to keep your child comfortable.
At Dentistry of West Bend, Dr. Harding gently examines your child’s teeth and takes digital X-rays to check on the development of permanent teeth below the gumline. He will evaluate whether the baby tooth is likely to fall out on its own or if an extraction is needed. Our pediatric dentistry team takes the time to explain what’s happening in your child’s mouth and what options are available.
What Happens During a Pediatric Dental Exam?
When you bring your child in for an exam, Dr. Harding will carefully examine the child’s jaw and assess the position of both the baby tooth and the permanent tooth. He will check to see if the baby tooth is loose and whether there is enough room for the permanent tooth to move into place.
Digital X-rays help Dr. Harding see what’s happening beneath the gumline. He can evaluate the development of other permanent teeth and identify any potential issues with spacing or alignment. This is also a good idea if your child is approaching the age when other adult teeth will start coming in.
If the baby tooth needs to be removed, the procedure is straightforward and gentle. Extractions are performed with care to ensure your child’s comfort. Removing the baby tooth creates space for the permanent tooth to shift into the correct position over time.
Can Shark Teeth Be Prevented?
Shark teeth are a natural part of child’s tooth development for some children, and there’s no way to prevent them entirely. However, maintaining good dental care habits can support healthy tooth development and reduce the risk of complications.
Encourage your child to wiggle loose baby teeth gently with their tongue or clean fingers. This can help speed up the natural process of the tooth falling out. Avoid forcing a tooth out before it’s ready, as this can cause discomfort or injury.
Regular dental checkups are essential for monitoring your child’s dental development. Dr. Harding recommends that children visit the dentist twice a year for exams and cleanings. These visits allow our team to track tooth eruption and catch any issues early.
Eating a balanced diet that includes crunchy fruits and vegetables can also support oral health. Chewing firm foods helps stimulate the gums and may encourage loose baby teeth to fall out naturally.
Will My Child Need an Orthodontic Evaluation?
In some cases, shark teeth may be an early sign that your child will need orthodontic treatment in the future. If there isn’t enough space in your child’s jaw for all the permanent teeth to come in properly, crowding or misalignment may develop.
Dr. Harding performs orthodontic evaluations as part of routine pediatric exams. If he identifies concerns about spacing or alignment, he may recommend an early orthodontic evaluation with a specialist. Early intervention can sometimes prevent more complex issues later.
However, not every child with shark teeth will need braces or other orthodontic treatment. Many children’s teeth align naturally as they grow. Careful monitoring during regular dental visits ensures that any issues are addressed at the right time.
How to Support Your Child’s Healthy Smile
As a parent, you play an important role in your child’s oral health. Establishing good habits early sets the foundation for a lifetime of healthy teeth and gums.
Make sure your child brushes twice a day with fluoride toothpaste and flosses daily. Supervise brushing until your child has the coordination to do it effectively on their own, usually around age seven or eight.
Limit sugary snacks and drinks, as these contribute to tooth decay. Choose nutritious options like cheese, yogurt, and fresh fruits to support strong teeth.
Talk to your child about what to expect during dental visits. Reading books about the dentist or bringing your child to the office before their appointment can help them feel more comfortable. At Dentistry of West Bend, we create a welcoming environment where children feel safe and cared for.
