Why do dogs’ teeth look different?

Dogs’ teeth have a very different shape to humans and, as such, are often described as being like a ‘machete’.

It turns out they’re not, as new research shows the shape of the teeth and their function are different to those of humans.

A team of scientists from the University of Warwick and University College London, led by Dr Paul O’Connor from Warwick University’s Department of Animal Science, have developed a model of canine teeth and found the shape is almost exactly the same for humans and dogs.

“When we looked at the teeth of dogs, we found that they were essentially identical,” Dr O’ Connor said.

So what’s the difference?

A ‘machinery of life’Dr O’Donnell said the teeth were shaped like “pancakes”, which is a term used for a tool used by humans to eat small prey.

Dr O’donnel said the idea that the teeth had a ‘factory of life’, similar to a human’s digestive system, was not supported by the data.

This is because teeth are not made of bone or teeth, but are made of soft tissue called cartilage.

“Dogs are designed to chew through hard, tough, and brittle materials,” Dr Paine said.

“In the case of teeth, the soft tissue is the cartilage, which is much more easily broken down by the teeth.”

Dr O’tonnel and his colleagues say they have now identified how the teeth are made and their functions, with teeth as “pants, pads, or mitts” which help to support the animal’s jaw and jawbone.

The study, published in the Journal of the American Veterinary Medical Association (JAVMA), also found that the shape and function of teeth are quite similar to those in the human digestive system.

In contrast, dogs’ dentures are much smaller than those in humans, and there are no bones in the tooth.

But while they are the same size in size, dogs have teeth which are much more “machinary” than those of a human.

The study found that dogs had teeth with “large and complex grooves”, which could be used to support teeth during chewing.

Dogs have “largely complete and highly differentiated” cartilage structures in their dentaries, but “many teeth” do not have cartilage to support them.

However, there was “little evidence that the structures of the dental system of the dog are different from those of the human, or that the dentary structure is functionally different from that of the canine,” the researchers said.

The findings were based on the use of a model, which included a 3D model of teeth and a 3-D model with teeth.

They found that both were much the same shape and the function of the dentures was very similar to that of teeth in humans.

However, the structure of the cartilaginous material on the tooth in the 3-d model was significantly different than the structure in the 2-d.

And there was no evidence that there were any differences in the shape or function of those cartilage components.

Dr OConnor said the findings suggested the teeth may function as “tools of life”, as a tool to hold food, to help the dog feed on, and to prevent chewing problems.

“When the dog is hungry, it does not need to use its teeth to dig in and to chew and its teeth have not had to be replaced,” he said.

“But when the dog has a problem with eating, it will try to dig into a larger food source.”

The study has also found teeth that were made of cartilage in humans and the same tooth in dogs, and was similar in both cases.

Dr Paine also said the study showed dogs do not need the same type of cartilages as humans, so it was possible that the two groups of teeth were different.

It could be that the cartils in the teeth in dogs were more easily replaced in humans or the cartillae of the bones in dogs may be more durable, he said, because dogs are able to digest more quickly.

“The teeth of humans and of dogs have been around for thousands of years and we are not seeing a major change in the way teeth are being used,” Dr Catt said.
