Shark teeth are more akin to cartilage than any bony or other hard structure. Consequently, they frequently break off during attacks / feeding. Luckily, the shark has multiple rows of teeth so that fresh ones move forward to replace lost ones.
Which makes me wonder if any given tooth stays in place long enough to be ravaged by cavities.
Or are there sharks that have other kinds of teeth and/or lack the replacement mechanism?
Breaking you neck can mean a whole bunch of different things. You can have burst fractures of C1, odontoid fractures of C2 (which is what a hangman’s noose breaks, causing heart and respiration centers to stop functioning), spinous fractures ,which are non life threatening, and compression fractures which are usually just painful and alter normal spinal dynamics. Anything that traumatizes the cord can cause paralysis. A tearing of the ligamentous structures can be far worse than a break; the swelling can compromise the spinal cord.
Buster Keaton performed all of his own stunts. He broke his neck doing one such stunt—by releasing a torrent of water from a water tower spout directly above him—while filming “Sherlock Jr.” (1924). The water smashed him to the ground, and he was knocked unconscious when his neck hit the rail of a railroad track. He suffered from headaches for some time after that. About a decade later, it is said, a doctor discovered the broken neck. In the interim, Buster continued to make great silent film comedies in which he continued to do all of his own stunts.
Maybe sharks don’t get cavities, but they are constantly losing teeth. That is why they have multiple rows of them, (similar, but not as many as a catfish) with new ones always growing in.
How the Blue Blazes could you break your neck and not know it? When I was 8 or 9 I suffered a partial fracture in my arm, and it hurt like all-get-out. I didn’t know the bone had been broken, though, until a few months later when I got an X-ray to determine my physical age. The doctor showed where I had a healed greenstick fracture. Right then I realized why it had hurt so damned much!

Where are the sharks getting the fluoride from?

Why would sharks worry about cavities? When they can regrow as many teeth as they lose?

I didn’t know Naismith looked like Teddy Roosevelt. Then again, I imagine a lot of men did back then.

Sharks also don’t eat sugar, so their cavity concern is minimal

Mr. Keaton was an awesome actor…check out “The General”, based on true events from the Civil War

I broke my neck in a motorcycle accident and didn’t find out until 25 years later when I had an MRI for an unrelated neck problem.
