Megalodon, the world’s largest known shark species, swam the oceans long before humans existed. Its teeth are all that’s left, and they tell a story of an apex predator that vanished.
A national dental care program is welcome news, but raises several ‘billion-dollar’ questions about how the program will work and what will be covered. Here are seven principles to guide decisions.
Canada’s health system does not include dental coverage, leaving a large gap in care that’s existed since its beginning. It’s time to ensure access to oral care.

Teens across millennia have yearned to explore, try new things and participate in risky behaviours. The key difference, however, seems to be the experience of a rebellion or restlessness.
We studied 8,000 primate teeth and finally confirmed that humans are not the only living primate to suffer from cavities. But there are interesting differences.
The researchers found tooth shape varied, depending on the types of food a carnivore regularly bites into – in much the same way we choose a kitchen knife depending on what we’re cutting up.
Many small animals make their teeth and claws from a smooth blend of proteins and heavy elements. These materials can form very sharp tools that make it possible to cut tough substances using tiny muscles.
Tassie devils are notorious scavengers, eating everything from echidnas to stranded whales. Understanding how their teeth wear down can help us feed and protect captive populations.
Are the descriptions of war passed down by ancient historians accurate? A site in Sicily provided a rare chance to fact-check stories told about two battles from more than 2,400 years ago.
