Chances are you like dinosaurs. At the very least, you find them interesting. Maybe you saw the new Jurassic Park movie or maybe the first one, so long ago, is one of your favorite movies and you can quote it at the drop of a hat. Or maybe, just maybe, you’re absolutely terrified of them and have reoccurring nightmares that you’re being chased through a dense jungle by a couple of angry (and hungry) Tyrannosaurus rexes.

Do you have a son or daughter? Do you read them storybooks about dinosaurs? Look, all we’re saying is that dinosaurs are trending right now (perhaps they’ve always been!) and it behooves us to educate you on a new problem regarding those reptilian skyscrapers – dental envy. Yes, dental envy. Let us elaborate, with the help of The Christian Science Monitor.

Sarah Caspari writes, “New research found that unique serrations make Tyrannosaurus teeth highly resistant to damage, thus helping the dinosaur and its relatives secure their place at the top of the prehistoric food chain.” What Caspari means is that there was one and only one reason as to why the Tyrannosaurus was on top of that dinosaur food chain: its teeth. Each T-rex had almost godlike teeth – looking like a collection of woodshed saws that allowed them to tear apart the flesh and bone of their prey, without so much as a dent or an ouch in their mouths.

Pretty convenient if you ask us. The article also compares T-rex teeth as being a whirling dervish of impossible steak knives that could damage rocks if the T-rex wanted to. What’s important though is that serrations when so deep that it prevented damage. What’s really interesting is that if by some unlucky chance the T-rex actually lost a tooth, it would grow back just like that. Humans can’t do that.

The long and short of it is that T-rexes had suit of armor teeth, nearly impermeable to damage, magic teeth that would grow back – all of this contributed to the T-rex climbing up that dino ladder and not letting go – being a super predator with impossible teeth and impeccable eating habits. Let’s just say the T-rex never had to go to the orthodontist or get dental surgery – and for that, we’re a little jealous; human teeth have a long way to go, which makes it important that you take special care of them!
