I once broke my tooth on some toffee my mom made. Every time I see a beaver, I think of that day and wonder how they can gnaw on trees all day without chipping an incisor when I couldn鈥檛 even conquer candy.
Since beavers are it鈥檚 not too surprising that their teeth constantly grow. This allows them to chew away on their sticks while keeping their teeth, but my guinea pigs are also rodents and I wouldn鈥檛 put them up against a log.
Beavers have another trick up their pelts though: their enamel. If you鈥檝e ever seen a beaver鈥檚 teeth you鈥檒l know that they appear pretty orange. This is because, whereas other rodents have magnesium in their tooth enamel, . So beavers have orange teeth for the same reason we have red blood.
The iron causes the orange colouring in beavers鈥� teeth, makes the teeth stronger against mechanical stress, and makes them . Researchers are using these new findings to look at ways of strengthening human teeth, which gives my dreams of candy-conquering new hope.
