For many kids, it can be difficult to distinguish the difference between the two shapes: a tooth’s head and body.

For that reason, many parents buy shark tooth necklace or bracelet and attach them to their child’s teeth.

But these products don’t work for everyone.

A new Australian research paper looks at how to tell which teeth are shark and which aren’t.

It found the answer is not obvious at first glance.

“The reason for the difficulty is that the teeth that look like teeth are actually tooth fragments that have fallen out of a shark’s mouth,” Dr Helen Tung said.

“These are the ones that actually form the dentition and are actually hard and can be hard to distinguish from the tooth.”

Dr Tung’s research is part of a larger project looking at the science behind how teeth form and function.

“We wanted to look at the mechanisms behind this tooth forming process, and what happens to it when it’s lost,” she said.

Dr Tun said she wanted to find out how sharks actually form their teeth and why it is different from the way people create and retain them.

“When you take a bite of a live shark, you see a lot of different shapes and sizes of tooth fragments.”

So we decided to use this data to investigate the mechanisms involved in the tooth forming of a tooth,” Dr Tung explained.”

It turns out that a shark teeth structure is actually a tooth fragment that has fallen out from a shark and is very similar to a tooth we have on our finger.

“Tooth fragments are the teeth’ main ingredient.”

There’s actually a lot more of them in a shark than in an average fish,” Dr Sreenan Jain, a professor of marine biology at James Cook University, said.

These pieces of tooth are usually about 2 millimetres in length and about a centimetre thick, but they can have a range of sizes.”

They are not necessarily that hard, but if they break, the fracture can be really deep and it can create a dentition that is very hard to remove,” Dr Jain said.

In some species, the fragments are formed during an initial stage of tooth formation called dentogenesis.”

This is when the shark’s jaws are able to hold the tooth in place,” Dr Laxmi Vaidyanathan, a research scientist at the University of Melbourne, said.”

When the shark is in the water, the tooth is already quite large and it doesn’t need to hold it in place.

“What happens when the tooth breaks is that it starts to deform and deform in an attempt to break it off.”

This process is known as dentosis and is caused by the shark taking in water and feeding on the fragments.

In humans, dentosis is usually due to damage to the tooth’s surface caused by an injury to the teeth or other causes.

“Our study showed that tooth fragments are not the only things that occur in sharks,” Dr Vaidyaanathan said.

This is why Dr Tun’s research looked at the way teeth form.

“If a shark has lost all of its teeth, it is a lot easier to remove the tooth fragments from a child’s jaw than it is to replace them,” she explained.

She said the teeth could have formed during this stage and then had to be lost to prevent the fragment from being too hard to break off.

“Tooth fragment fracture is not caused by anything specific in the jaw.

It’s caused by water movement and food that has moved in,” Dr Breen said.

“And it can happen very quickly, and we think that it’s not as important to prevent it as it is simply to ensure that the dentin can regenerate.”

The researchers found that a tooth fragments had a much harder time forming the dentent of a child compared to teeth from other species.

“In the case of a baby shark, they break quite easily and can go a long way and that’s where the tooth can be lost,” Dr Goh said.
