How common is our Moon's orbit which causes it to always show us the same face to Earth?

As stated in the title, is it common for other planetary moons to show the same face to the body they orbit? If not, are there any theories as to how our moon's orbit evolved as such. If so, what causes this to happen?

It's quite common, essentially all the large moons in the solar system are tidally locked to their planet. It's not a random occurrence, it happens because the gravitational gradient from the planet exerts a drag on the rotation of the moon that gradually slows it down until its rotation and its orbit are in synch.
