Ever wonder why sharks have so many differently shaped teeth or why they keep regrowing throughout their lives? Dr. David ...

"We applied engineering techniques to digitally simulate how different tooth shapes handled bite forces and loads resulting from lateral head movements,” said Antonio Ballell, doctoral student at the ...

Meat eating animals have teeth like this, for slicing and ripping. You should try giving him a steak. Carnivores and herbivores have different types of teeth, to suit the type of food they eat.

As well as targeting different species, the variation in shape may have reflected different killing styles, with slender teeth suited to ripping into the softer but harder-to-reach parts of prey.

They compared these measurements with the participants’ genetic information and identified 18 genome regions that influence the size and shape of different groups of teeth. One of the genes is ...

If we only had canine teeth, we would be well adapted for eating meat. Fortunately, we have a combination of different kinds of teeth, that enables us to eat a wide range of foods. Let's take a ...
