Shark teeth, in the context of "shark teeth" in children (when a permanent tooth erupts behind a still-present baby tooth), move into their proper position primarily thanks to pressure from the tongue.
Here's a more detailed explanation:
-
The "Shark Teeth" Phenomenon: "Shark teeth" occur when permanent teeth erupt behind the baby teeth because the baby teeth haven't fallen out yet. This is more common in the lower front teeth.
-
Natural Resolution: In most cases, the permanent teeth will move forward on their own.
-
The Role of the Tongue: The tongue exerts constant pressure on the teeth. This pressure helps push the permanent tooth forward into the correct position once the baby tooth is loose enough or extracted.
-
Baby Tooth Extraction: Sometimes, the baby tooth needs to be extracted to allow the permanent tooth to move into place. If the baby tooth remains firmly in place, the permanent tooth may not be able to shift properly.
-
Orthodontic Intervention: In rare cases where the permanent tooth is severely misaligned or there isn't enough space, orthodontic treatment might be necessary.
In summary, while the emergence of permanent teeth exerts some force, the tongue plays a key role in guiding shark teeth into the correct position after the baby teeth are gone.
