In brief: Yes

You can break porcelain in the same way that you can break a tooth.
While we have very strong ceramics today, excess force must be dissipated in some way. Teeth can be loosened, or become sensitive. So, the real question is how do I reduce the force in my mouth so none of these things occur. It is correcting a bad bite that is key, not stronger materials.

In brief: Yes,unless cast gold

A crown which has either a metal (gold alloy or non-precious) or ceramic substrate with porcelain added to complete the natural appearance and function is no stronger than a natural tooth.
Ice chewing, hard candy, opening pop bottles, etc... Still need to be avoided. A back tooth crown made of a cast gold alloy can get re-decay, but won't break as it is a solid, single cast unit.

In brief: Yes

Occlusal forces can be very strong and often times are too much for the porcelain on crowns to withstand.
Even though strong crown materials are getting more esthetic (eg zirconia), gold and all metal crowns usually stand up to strong chewing forces best.

In brief: Yes

Because the chewing or grinding forces on it exceed the capacity of the crown materials.

All dental crowns have the potential to fracture except a solid gold crown.

Yes. recurrent decay, gum disease, trauma can weaken or allow breakage of the tooth under the crown.

In brief: YES

If you can break a tooth, you can break a crown.
Under normal chewing conditions a crown should not break. Bite down on something hard, like a pit or metal, and it could fracture.

In brief: Yes and No

Yes all porcelain, and porcelain covered metal crowns.
Not cast gold or silver colored. Mosy dds/dmd prefer to use only gold on second molars(last tooth in back for most). It rarely shows when you smile.

In brief: It depends!

Porcelain or tooth colored crowns can break for a variety of reasons.
All metal crowns can not break but they too can fail due to recurrent decay or occlusal wear. The tooth under the crown can break causing the entire crown to come loose and may as a result be rendered useless.
