5. Tooth Records
• The hardest teeth
The Mohs scale is used to measure the hardness level of objects. Talc, for example, is number 1 on the scale because you can scrape it with your fingernails. Diamond is at 10 on the hardness scale and is the hardest natural mineral. It can only be cut with another diamond. Mouse teeth are 9.6!
• The most teeth
The biggest and heaviest teeth
The elephant has the biggest and heaviest teeth. In 1897, an elephant was shot whose tusks weighed 465 lb (211 kg). Around 1900, a tusk from an unknown elephant was found to weigh 257 lb (117 kg). The longest tusks belonged to the extinct straight-tusked elephant. They were an impressive 16.4 ft (5 m) long! You can actually only see 2/3 of an elephant’s tusks; the rest is firmly anchored to its skull.
4. Third Set of Teeth? Elephants Have a Fifth Set of Teeth!
Most mammals only have two sets of teeth. The first set grow in childhood, and the second set follow in adulthood. Elephants actually have a fifth set of molars in their mouths. If this fifth set breaks in the elephant’s old age, the animal will starve.
3. Rat Teeth Carry on Growing
That’s why they have to keep nibbling and gnawing away to keep them short. If one tooth is lost, it’s possible that the tooth above or below it might grow through the gap as there’s nothing to stop it. Rabbit teeth also never stop growing.
2. Even Mosquitoes Have Teeth
47 of them to be precise. Snails also have teeth. They have around 25,000 tooth-like growths on their tongues.
