If we hit them with enough force, they will obviously shatter. But what about from every day use? Does every little bump slowly crack them with micro-fractures that will build up over time, or do they have some form of elasticity or other kind of self repair?

Generally speaking, there is a minimum amount of stress that is needed to get a material to break. Normal use stays within those limits. One of your guesses is correct as well: even seemingly rigid materials accommodate some degree of elastic deformation.
