The big teeth growing behind baby teeth are actually permanent teeth that are erupting. This phenomenon is sometimes called "shark teeth."
Understanding "Shark Teeth"
When a child's permanent teeth start to come in while their baby teeth haven't yet fallen out, the permanent teeth may emerge behind the baby teeth. This creates a double row of teeth, similar to a sharkâs multiple rows of teeth, hence the name. This often occurs when the permanent teeth begin to erupt, typically around the ages of 5-7 years old.
Why Does This Happen?
- Natural Tooth Development: Permanent teeth develop in the gums below baby teeth.
- Timing Differences: Sometimes the permanent tooth begins to erupt before the baby tooth is ready to fall out.
- Root Resorption: Normally, the roots of baby teeth dissolve as the permanent teeth prepare to erupt, allowing the baby teeth to loosen and fall out. If this doesn't happen in time, the permanent tooth will erupt behind the baby tooth.
Common Locations
"Shark teeth" most commonly occur in the:
- Lower front teeth (mandibular incisors)
- Upper front teeth (maxillary incisors)
What To Do If You See Shark Teeth
- Monitor the Situation: Often the baby tooth will fall out on its own, and the permanent tooth will move into the correct position.
- Consult a Dentist: If the baby tooth does not fall out after a few weeks or if the permanent tooth is causing any pain or discomfort, schedule an appointment with a dentist.
- Possible Extraction: A dentist may recommend extracting the baby tooth to allow the permanent tooth to move into its proper place.
Key Takeaways
- "Shark teeth" is a term for permanent teeth erupting behind baby teeth.
- It's a common occurrence during the transition from baby teeth to permanent teeth.
- A dentist can help ensure proper alignment if the issue does not resolve itself.
