Shark Teeth

It seems like sharks are everywhere these days—on land, sea, and air(waves). A halftime show meme gone viral. A week of summer TV devoted to our favorite apex predators. And who doesn’t have “Baby Shark” playing in their heads all day once they’ve heard it? But are we jumping the shark to discuss this topic in an orthodontic blog?

Not at all! Because today, we’re going to talk about shark teeth—just not the ones you might be expecting.

One of the expected sights when a shark opens its mouth are those rows and rows of shiny shark teeth. Sharks can grow from two to 15 rows of teeth at any one time (and some sharks have even more). This means sharp new teeth are always ready to replace any shark tooth which is lost, broken, or worn out.

An unexpected sight? When children point to their new adult tooth or teeth coming in—right behind their still-firmly rooted baby teeth! This double set of teeth is called “shark teeth,” and, while it certainly might come as a surprise, it’s not all that uncommon. But why do children develop shark teeth at all?

After all, baby, or primary, teeth have small roots, and are designed to come out easily when the adult teeth start arriving. When a permanent tooth starts to erupt, it pushes against the root of the baby tooth above it. This pressure gradually dissolves the root of the primary tooth, and with nothing to anchor it, it’s now loose, wiggly, and ready to fall out. That’s why baby teeth often look like they have no roots at all when they eventually wiggle free.

Sometimes, though, the roots of a primary tooth don’t break down, which means baby teeth stay right where they are. It also means that the permanent teeth have to erupt somewhere else—usually behind those stubborn little baby teeth.

Shark teeth can first appear around the ages of five to seven when the permanent front teeth start arriving, or several years later, when the adult molars begin to come in. Any extra teeth in one small jaw naturally raise concerns about tooth misalignment, especially when those extra teeth are molars. If double molars are causing crowding, it’s a good time for your child to have an orthodontic examination at our Yuba City office to make sure the permanent teeth are properly positioned.

Unlike sharks, we don’t have an endless supply of replacement teeth, so it’s understandable to worry when you see anything unexpected. If you want to know more about shark teeth, or if you have any concerns, don’t hesitate to call Dr. Adam Hoybjerg for expert advice.
