Can human teeth be sharp?
Also known as Cuspids, canines are the sharp, pointed teeth on either side of our incisors. These teeth are used to tear and rip food apart. You have four cuspids in your mouth.

These teeth act something like a hunting knife — they cut easily through tough flesh and bone. Many sharks have combinations of long pointed teeth and wider serrated teeth, so they can hold their prey in place while they cut into it.
Can shark teeth break?
Sharks typically break off and lose at least 1 tooth a week. When a shark’s tooth falls out, another spins forward like a conveyor belt from their rows of backup teeth. The dull, broken or worn teeth are quickly replaced by a sharp new tooth. A shark may grow and use over 50,000 teeth in it’s lifetime!
Are human jaws as strong as sharks?
Great white sharks are also among the largest fish in the world, and can bite with a power of up to 4,000 pounds per square inch (PSI). That is twenty times stronger than the average human bite force, ten times stronger than the average wolf bite force, and seventeen times stronger than the average pit bull bite force.
What do sharks confuse humans with?
Among surfers, there’s a commonly held belief that shark attacks are mostly a case of mistaken identity. The apex predators take a bite out of swimmers because they resemble seals and sea lions—especially when they’re on a surfboard.
Do sharks view humans as prey?
But despite being potentially such an easy meal, sharks are really not that interested in hunting humans. “They generally just ignore people.
How strong are human teeth?

Are shark teeth weak?
Shark teeth are weak due to a lack of good roots. As a result, they readily fall out. In fact, a shark’s teeth fall out and grow back in a continual cycle throughout its life. However, it is a fallacy to have the perception that having weak teeth means you may easily break a shark’s teeth.
