All pigs are born with "tusks"

Of course when they are young, they are just the size of teeth, but grow quite long.

When raising hogs, the tusk teeth are removed or clipped and stunted.

As was stated, in a feral state these domestic pigs revert back quite quickly to dangerous animals.

I found a skull of a young wild pig recently, and the tusks seem to lie along the inside of the jawbone. these were about three inches long or so and were curved so that when they grew out they naturally turned outward.
It was pretty cool seeing how they work.
