The average human is born with two full sets of teeth. The average human then proceeds to grow and lose the primary set before the permanent adult set grow in (four wisdom teeth included). The average human has around seven fillings and 3.28 decayed or missing permanent teeth, give or take the minority of exceptions.
More recently (as of 1998, to be precise) around 1/300 adults develop a condition called Lazaradentinitus, more commonly known as Shark Jaw Syndrome. The only known symptoms of this so far are a lack of pigmentation in the adult's gums, rapid tooth loss and rapid regrowth. These regrown teeth are far more frail and loose than their original permanent set, making them far more likely to be broken or even ingrown in some cases.
These newer sets of teeth are much harder to spot on an x-ray than an original set of adult teeth in a child, in fact they don't seem to be made of enamel at all but some hybrid mixture of semi-petrified flesh with an enamel-like coating more akin to the thickness of a fingernail than solid tooth. As a result of the petrification, the gums and surrounding skin are often discoloured, usually with a distinct shade of grey which further lends the disease to the moniker of "Shark Jaws".
While everyone over the age of eighteen is advised to keep a close eye on the colour of their gums and report any signs of change, there have been 102 casualties directly linked to the condition with a potential 38 others whose cause of death can't be confirmed as solely Shark Jaws Syndrome. The most frequent ways in which the patients die are either an undetected infection that's managed to spread to the brain or close enough to cause severe nerve damage and seizures or they choke to death in their sleep as they inhale their own teeth.
